Hi
    Does anyone know a procedure/macro to generate random strings ?
    Do you want to write it ?
      :t


    EDIT: i wrote something about it.       

Something like this?

include \masm32\MasmBasic\MasmBasic.inc      ; download (http://masm32.com/board/index.php?topic=94.0)
  Init
  LenMin=5
  LenMax=50
  xor esi, esi
  Dim My$()
  Let edi=New$(LenMax+1)
  .Repeat
      push edi
      add Rand(LenMax-LenMin), LenMin
      push eax
      xor ecx, ecx
      .Repeat
            add Rand(26), "a"
            stosb
            inc ecx
      .Until ecx>=stack
      pop eax
      xor eax, eax
      stosb
      pop edi
      Let My$(esi)=edi
      inc esi
  .Until esi>=1000
  Store "Random.txt", My$()
  Inkey Str$("%i strings generated", eax)
  Exit
end start

It is more fun if you get a spelling dictionary, and randomly select words and concatenate them to the desired random string length then terminate the line.

Dave.

my concern is more toward the test you devise   :t

if you generate a set of random strings for a test
it's only fair if you use the same set on each routine tested
rather than generating a different set for each test run

Dave,

Agreed! Write the file with the random data, then test with different programs.

Dave.

 :biggrin:
Thanks all,
                  i started to think about this yesterday but now i have some new ideas.

Back on topic, do you mean random letters or words?

With most pseudo-random number generators including Rand() (http://www.webalice.it/jj2006/MasmBasicQuickReference.htm#Mb1030), you get the same set anyway - unless you explicitly set a new seed. So that shouldn't be a problem.

you can see how one set of random strings might yield very different results from another
especially seeing as you have been working on sort routines, lately   :P

sinsi,

I am glad you approve of the method of encouraging our spamming friends to post else where.  :P

             may be sets of random letters/numbers

Hi Dave,
              Yes it must be  :t

Hi
        2 procedures to compare 2 "strings
        with spaces":       
                              CompareStringXYS    <- compare DWORDS
                              CompareStringXYBS   <- compare BYTES

note that: "abcdef"  is EQUAL to "a b c d e      F"
                  For example, many times, we have product names which name
                  is nearly EQUAL. And they have spaces between words.

        Could you post your results ?
        Thanks

Jochen,
              add some other procedures that you know
              and test it.
              Thanks  :t

for students and it is just "real life" also ! :biggrin:
                 but not only Jochen ! If the input procedure clean spaces ...
                 For instance, the date field. We need to test if it is correct
                 and we remove spaces in that time: "2088- 02- 30" just

Dave,
      9 downloads and only your answer
      which seems to mean that they
      dont want to help but the code(?)
      Ok thank you.  :t

Last results:

      CompareStringXYS  -> remove spaces, convert to uppercase
                           and copy to stack;
                           load dwords, compare.
      CompareStringXYBS -> remove spaces, convert to uppercase
                           and copy to stack;
                           load bytes, compare.
      CompareStringXYT  -> load byte, remove space,
                           convert to uppercase
                           compare.

      Have you anyone to compare ?

Gunther,
          Thanks  :t
          Could you run this new to copy strings,
          please ?

          EDIT: my results seems to mean that working with
                    strings with length is better than null terminated.
                    (far better!). My strings have length and null terminator also.
                    So when i copy they have the null terminator.

Gunther,
              thank you !  :t
              i added yours results in my reply 37.
              We have 3 different set of results.
              szCopy from MASM is only better in i7
              to copy null terminated strings but not
              for all cases.

              We have 3 different set of results.

Don't forget: We've different processors, too.

Gunther

 Yes see reply #37 we see i7 ...

Gunther,
          Thank you for your work !
          Now i am testing this new procedures
          Could you run this new to copy strings,
          please ?

          NOTE: when i copy the length, the string is null terminated also.
                     All lengths are in the strings.

results from Gunther (thanks  :t ):

Hi Gunther,             
                     thank you !  :t                
                     i added yours results in my reply #42 (see it).
                     impressive!
                    Your i7 is 4 times more powerful (+/-)!

Hi
    Now, i am testing this new 2 procedures
    (versions A...E)
    Could you post your results, please ?
    Thanks

These are my results.

Hi Rui,

the attached archive contains the results.

Hi
    Thank you ninud
    and
    thank you also Gunther  :t

When we read each procedure, we have no doubts,
the best are: XZE, XZZE or XZZF
(they are perfect solutions -for all cases).

But when we read the results,
the best seems to be XZZA, XZZB or XZZC!

one conclusion: XZZ seems to be better than XZ
but i need to study this results with more time
(but not from my results).

XZ  uses:    mov  eax, [esi+edx*4]
XZZ uses:   mov  eax, [esi+edx]

Hi,

   Do you want results from older processors?

HTH,

Steve N.

Thanks you Steve,  :t

The same conclusion as before:
XZZA, XZZB, XZZC are better !!!

Rui

here are mine results

Olá guga!
                   obrigado ! :t

The same conclusion:
XZZA, XZZB, XZZC are better as before !
XZZC seems to be better.

But when we read each procedure, we have no doubts,
the best are: XZE, XZZE or XZZF
(note: all these procedures were written by me)

Hi Jochen,
           Thank you for your work !
            :icon14:
-----------------------------------
contradictions are SOLVED ?
-----------------------------------
As i said:
When we read each procedure, we have no doubts,
the best are: XZE, XZZE or XZZF
(they are perfect solutions- for all cases).

note I: XZ  uses:   mov  eax, [esi+edx*4]
           XZZ uses:   mov  eax, [esi+edx]
           ZE   uses:   shr, shl
           ZF   uses:   and

note II: these procedures doesn't use cmp or test instructions
             but only operations and negative counters.

Rui, your  algo demands that the string have fixed lenght, right ?

I mean, you need to predefine the lenght. Ex:

[MyString: D$ 4
                 B$ "Guga", 0]

Can you do it without the predefinition, and making it works according oinly to the null termination "0" ?

Or it was designed only to work with predefined strings lens ?

guga, see my reply #42 where we used null terminated and we compare szCopy with _WZ. You are right my strings have a predefined length and they are far better than null terminated. See the results. I predefine the length in this way
---------------------------------------------------
.data
           dd 4              <--- here the length
sguga db "guga",0  -----> it is also null terminated because the system needs it.
---------------------------------------------------
In the next set of tests we may see the results when we want to add one to another. Se quiseres o _WZ eu envio-te.  :t

I´ll read it.

But...if it uses a fixed len, there is no need to also search for the null termination ;) It would be a bit faster if you avoided the check for the zero ending. If it needs only 4 bytes ("Guga") checking the ending 0 (5th byte) is unnecessary since the len (4) is already defined.

Eu gostaria de ver o _WZ sim. Parece interessante para determinados tipos de dados (e não apenas strings). Digo, se vc tirar a checagem pela terminação em zero (ele ficará um pouco mais rápido e tb vai estar em conformidade com a funcionalidade do algoritmo em si), vc pode usar o algoritmo para copiar toda uma gama de dados e não apenas "strings". Principalmente, pq é um meio alternativo (e mais rapido) de se copiar a memória, por exemplo, como um substituto para funções como memcpy.

guga, claro que eu não testo o zero, só serve para o OS se  e quando for preciso.
Eu já te envio.
note: these procedures doesn't use cmp or test or
         similar instructions but only operations and negative counters.
         (predefined length)

    . all follow the same procedures as to copy strings.
    . In these procedures, it is not possible to add
      201 bytes if the maximum is defined for 200.
    . If the string contains 199 bytes and we try to
      add 1000 we add only 1 byte and exit.
    . ADDAtoB_X stringA, stringB    <<<- add A to B

    . In these examples, we add 0,1,2,3,4,15,55,103,203,503,1027
      to one that contains 11 bytes and the maximum is 1100.
   
    Could you post your results, please ?
    Thank you  :t

Hi,

   Three older processors, P-III, Pentium M, and P-MMX.  The
last seems to vary a bit from run to run.  66597 milliseconds
was larger in the first run.

Regards,

Steve N.

Rui,

the result is attached.

Gunther

Thank you, Steve  :t

psst - FORTRANS is Steve   :biggrin:

i haven't been running these, because we have essentially the same processor
my results will always look like yours

Dave, i did a correction in 2 posts  :t

Thank you Gunther,  :t

XZZF seems to be better here with 137 milliseconds to ADD 1027 bytes
and we got the same 137 to MOV 1027 bytes with XZZC (see my reply #48)!

IS THIS GOOD ? What do you think ?

Hi
--------------------------------
Insert a string to another
--------------------------------

    . INSAtoB_X is the reference procedure:
      move and add only BYTES;
    . all other move/add DWORDS+BYTES;
    . INSAtoB_X stringA, stringB, Position    <<<- insert A into B

    . In these examples, we insert 0,1,2,3,4,15,55,103,203,503,1027
      to one that contains 100 bytes.

    Gunther, could you post your results, please ?
    Thank you  :t

Hi Rui,

    Gunther, could you post your results, please ?
    Thank you  :t

No problem. Do you need the results of all 3 attachments? I can do it this evening.

Gunther

Hi Gunther,
                   yes for all 3, if you dont mind
                   Thanks.

In the following example, each procedure
moves 100 bytes (string length) to the right
to insert strings at position 0.

Strange result (i need to see why: nothing wrong!):

Quote
289 milliseconds, INSAtoB_XZZE-1027 bytes
492 milliseconds, INSAtoB_XZZE- 503 bytes   

INSAtoB_X   ->>> moves only BYTES

INSAtoB_BA and INSAtoB_BB use an auxiliary buffer

INSAtoB_BA   ->>> moves only BYTES
INSAtoB_BB   ->>> moves DWORDS+BYTES

It seems that "auxiliary buffer" is not a good idea.

Thank you so much, Gunther  :t

XZZE or XZZF are good options

18 milliseconds to insert 55 bytes at the middle
seems to be good.

Yes, indeed. Not so bad.

Gunther

Hi Gunther  :t
              In my reply #71 we see that we need 137 milliseconds to MOV or ADD 1027 bytes. Now, to insert at position 50, moving bytes (50 bytes), we need 155 milliseconds to insert 1027 bytes. Seems to be good. Of course, in your powerful i7 !
note: "moving bytes" means DWORDS+BYTES. If we need to move 15 bytes, we move 3 DWORDS + 3 BYTES.

Hi Rui
here is a function i made that you could adapt to your needs or even improve it. It copies from 128 to 128 bits.

It works for strings or any other data set. Didn´t fully tested, but so far t is very very fast.


; A replacement for memcpy inside msvcrt.dll. Fast memory copy of large buffers. It copies from 128 to 128 bits at once. (4 Dwords)
Proc memcpy:
    Arguments @pDest, @pSource, @Length
    Uses esi, edi, ecx, edx, eax

    mov edi D@pDest
    mov esi D@pSource

    ; we are copying a memory from 128 to 128 bytes at once
    mov ecx D@Length
    mov eax ecx | shr ecx 4 ; integer count. Divide by 16 (4 dwords)
    mov edx ecx | shl edx 4 | sub eax edx ; remainder

    xor edx edx ; here it is used as an index
    While ecx <> 0
        movupd XMM1 X$esi+edx*8 ; copy the 1st 4 dwords from esi to register XMM
        movupd X$edi+edx*8 XMM1 ; copy the 1st 4 dwords from register XMM to edi
        add edx 2 ; we are copying the 128 bits. So instead simply inc by 1, we made it by 2, because each index holds only 8 bytes (limitation of the operand multiplication edx*8 / esi*8 etc)
                  ; So, when edx = 0. edx*8 = 0. X$esi will point to esi+0 bytes
                  ; when edx = 2. edx*8*2 = edx*16. X$esi will point to esi+16 bytes
                  ; when edx = 4. edx*8*4 =edx*32. X$esi will point to esi+32  bytes.
                  ; So. The important is that after each loop esiand edi must points 16 bytes ahead.
        dec ecx   ; ecx is our counter. It simply computes the lenght/16. Why 16 ? because we are jumping from 4 to 4 dwords. Which means that the loop is 16 x faster then using a regular byte by byte operation.
    End_While
    emms ; clear the regsters back to use on FPU
    shl edx 3 ; mul edx by 8 to get the pos
    add edi edx
    add esi edx

    ; If the memory of not 4 dword aligned we may have some remainder here So, just clean them.
    mov ecx eax
    While ecx <> 0
        movsb
        dec ecx
    End_While

EndP


Hi Gustavo,

The emms must be a leftover from previous MMX versions ;-)

BTW memcpy has been beaten to death here (http://www.masmforum.com/board/index.php?topic=11454.msg87609#msg87609).

Hi JJ, tks

I searched the link, but the file was deleted from the old forum. Do you have the source for the memcpy so i can test ?

Btw..the memcpy is from lingo ? He usually code well for speed.

I found one from my old copy of the 2012 masm form


regcopy proc src:DWORD,dst:DWORD,ln:DWORD

    push ebx
    push esi
    push edi
    push ebp

    mov esi, [esp+4+16]     ; src
    mov edi, [esp+8+16]     ; dst
    mov ecx, [esp+12+16]    ; ln

    shr ecx, 4              ; div by 16
    jz tail

  @@:
    mov eax, [esi]
    mov ebx, [esi+4]
    mov edx, [esi+8]
    mov ebp, [esi+12]
    mov [edi], eax
    mov [edi+4], ebx
    mov [edi+8], edx
    mov [edi+12], ebp
    add esi, 16
    add edi, 16
    sub ecx, 1
    jns @B

  tail:
    mov ecx, [esp+12+16]    ; ln
    and ecx, 4
    jz quit

  @@:
    movzx eax, BYTE PTR [esi]
    mov [edi], al

    add edi, 1
    sub ecx, 1
    jnz @B

  quit:
    pop ebp
    pop edi
    pop esi
    pop ebx

    ret 12

regcopy endp


But...If is this one....on my tests, the function i made is twice as faster ? Or im analyzing the wrong function to test ?

Tks JJ. I forgot I was already tested it :)

I´ll take a look and test on the new BenchMark Template app

Hi
In the following example, each procedure
moves 100 bytes (string length) to the right
to insert strings at position 0.

This is my first version with SSE instructions

INSAtoB_SSEE uses «movups  xmm0,[...]»

    Gunther, could you run it, please ?
    Thanks

Hi
        What is «movupd» ?

        Where can i see this instructions (a good reference)

        I am not able to assemble this:
        movups      xmm1, [esi+edx*8]

        I GET: instruction or register not accepted in current CPU mode

MOVUPD is an SSE2 instruction, which are supported since MASM v6.15  (6.14 does only support SSE). Also I would recommend you to use MOVDQU instead, because you are not dealing with FP data.

qWord,
             «Did you never heard of Intel's and AMD's developer manuals?»
              No, noone knows it ! :P
              I want to use movupd because guga used it.
              Thanks.
Dave,
              Thanks  :t

Great idea Qword. Tks for reminding  :t.

It is always worth to keep compatibility for olders CPUs...but....I don´t recall of a unaligned instruction for SSE - except movups that is for  FPU data. Does SSE1 have similar instruction movdqu (SSE2) ?

Rui, you may use movdqu insetad. It won´t change anything the performance (If i recall well on Agner´s Fog recommendations )

Quote from: Agner´s Fog Optimization Manual
"Using unaligned read instructions
The instructions MOVDQU, MOVUPS, MOVUPD and LDDQU are all able to read unaligned vectors.
LDDQU is faster than the alternatives on P4E and PM processors, but not on any later processors. The unaligned read instructions are relatively slow on older Intel processors
and on Intel Atom, but fast on Nehalem and later Intel processors as well as on AMD and VIA processors.
; Example 13.10. Unaligned vector read
; esi contains pointer to unaligned array
movdqu xmm0, [esi] ; Read vector unaligned
On contemporary processors, there is no penalty for using the unaligned instruction MOVDQU rather than the aligned MOVDQA if the data are in fact aligned. Therefore, it is convenient to
use MOVDQU if you are not sure whether the data are aligned or not."

Ref: http://www.agner.org/optimize/blog/read.php?i=285

So, you can try using the following code:



Proc memcpy_SSE_V3:
    Arguments @pDest, @pSource, @Length
    Uses esi, edi, ecx, edx, eax

    mov edi D@pDest
    mov esi D@pSource
    ; we are copying a memory from 128 to 128 bytes at once
    mov ecx D@Length
    mov eax ecx | shr ecx 4 ; integer count. Divide by 16 (4 dwords)
    jz L0> ; The memory size if smaller then 16 bytes long. Jmp over

        ; No we must compute he remainder, to see how many times we will loop
        mov edx ecx | shl edx 4 | sub eax edx ; remainder. It can only have be 0 to 15 remainders bytes
        mov edx 0 ; here it is used as an index
        L1:
            movdqu XMM1 X$esi+edx*8 ; copy the 1st 4 dwords from esi to register XMM
            movdqu X$edi+edx*8 XMM1 ; copy the 1st 4 dwords from register XMM to edi
            dec ecx
            lea edx D$edx+2
            jnz L1<
        test eax eax | jz L4> ; No remainders ? Exit
        jmp L9> ; jmp to the remainder computation

L0:
   ; If we are here, It means that the data is smaller then 16 bytes, and we ned to compute the remainder.
   mov edx ecx | shl edx 4 | sub eax edx ; remainder. It can only have be 0 to 15 remainders bytes

L2:

    ; If the memory is not 4 dword aligned we may have some remainder here So, just clean them.
    test eax eax | jz L4>  ; No remainders ? Exit
L9:
        lea edi D$edi+edx*8 ; mul edx by 8 to get the pos
        lea esi D$esi+edx*8 ; mul edx by 8 to get the pos

L3:  movsb | dec eax | jnz L3<

L4:

EndP


Another version that uses SSE1 here seems a bit faster. (About 3% faster), but still uses as FPU (I couldn´t find an alternative for movups yet :( )

Try this....


Proc memcpy_SSE_V4:
    Arguments @pDest, @pSource, @Length
    Uses esi, edi, ecx, edx, eax

    mov edi D@pDest
    mov esi D@pSource
    ; we are copying a memory from 128 to 128 bytes at once
    mov ecx D@Length
    mov eax ecx | shr ecx 4 ; integer count. Divide by 16 (4 dwords)
    jz L0> ; The memory size if smaller then 16 bytes long. Jmp over

        ; No we must compute he remainder, to see how many times we will loop
        mov edx ecx | shl edx 4 | sub eax edx ; remainder. It can only have be 0 to 15 remainders bytes
        mov edx 0 ; here it is used as an index
        L1:
            lddqu XMM1 X$esi+edx*8 ; copy the 1st 4 dwords from esi to register XMM
            movups X$edi+edx*8 XMM1 ; copy the 1st 4 dwords from register XMM to edi
            dec ecx
            lea edx D$edx+2
            jnz L1<
        test eax eax | jz L4> ; No remainders ? Exit
        jmp L9> ; jmp to the remainder computation

L0:
   ; If we are here, It means that the data is smaller then 16 bytes, and we ned to compute the remainder.
   mov edx ecx | shl edx 4 | sub eax edx ; remainder. It can only have be 0 to 15 remainders bytes

that's GoAsm syntax, Gustavo
Dave <--- Masm guy   :biggrin:

Hmm...i don´t remember the proper syntax for masm.

But it should be something like:


ZeroMem_SSE Proc
    pMem:DWORD, Length:DWORD

    Uses esi, edi, ecx, edx, eax <---Just a RosAsm macro to push/pop those registers after and before the end of a function

    mov edi pMem
    ; we are copying a memory from 128 to 128 bytes at once
    mov ecx Length
    mov eax ecx
    shr ecx 4 ; integer count. Divide by 16 (4 dwords)
    jz L0 ; The memory size if smaller then 16 bytes long. Jmp over
        PREFETCHNTA Byte ptr [edi]
        align 16 <---- don´t recall the syntax for masm...but should be the same
        pxor XMM1 XMM1 ; clear XMM1 register
        ; No we must compute he remainder, to see how many times we will loop
        mov edx ecx | shl edx 4 | sub eax edx ; remainder. It can only have be 0 to 15 remainders bytes
        mov edx 0 ; here it is used as an index

L4:

ZeroMem_SSE endp

Although it has been some years since i last coded using masm syntax, basically both are not at all that different (except, for the macros usage). The main differences i see is due to the fact that on RosAsm we must set the size directive to make easier to "see" what is a dword a word, byte etc.
D$ = dword ptr etc
W$ = word ptr etc
B$ = byte ptr
X$ = any type size used mainly in SSE
T$ = terabyte ptr
F$ = floating ptr
R$ = real floating ptr
Q$ = quadword ptr

Those are the mainly differences.

The rest is basically from the usage or not of the macros (I like to use due to readability)

T is probably TenByte Ptr   :P

 :biggrin: my bad  :icon_mrgreen: TenByte not "Terabyte" :icon_mrgreen: :icon_mrgreen:

I've given it a try, Gustavo - version 0.01 of Ros2Masm attached here (http://masm32.com/board/index.php?topic=3375.msg35680#msg35680).below.
It expects a text file in the commandline; if there is no argument, RosAsmTest.asm is assumed. Use Console Build All in qEditor.

you have to test aligned and unaligned starting addresses, of course   :P

WOW..great work, JJ :t :t

 :icon_mrgreen: Sure, dave. The aligned version works faster :):):)

I tested it here and it works like a gem . Many tks :t

Hi guga

I couldn't do anything this weekend. I was sick (and...).
About your memcpy_SSE_V4, you should improve it

    1. If it jumps to L0, ECX=0.
        So we don't need to do this: mov edx ecx | shl edx 4
    2. L2 is not used
    3. If we do «sub eax edx» we don't need: test eax eax
       but only jz L4>

Hi,
        These are my results.
       
        MOVEAtoB_SSEG is a macro with your V4 (+/-)
        (MOVEAtoB_SSEG srcName, dstName, cpyLen)
       
        Could you post your results ?

        Gunther, could you run this CopyString47, and CopyString48, please ?
        Thanks

Hi,
        Now, i used crt_memcpy, memcpy_1, memcpy_2, memcpy_3
        procedures.
        Copying 16 bytes at a time we don't get the best results in my P4.

        The versions YZZE, YZZG and YZZH copy 16 bytes at a time using
        the 32 bit registers.
        The strings are not aligned.
       
        Gunther, could you post your results, if you dont mind ?
        Thank you.
       
        These are my results.

Hi Rui,

the results of #47 and #48 are attached. copy.zip is the archive's name.

Gunther

Thank you Gunther  :t

In your powerful i7, _SSEE is the best

Now, i would like to know the results for CopyString53
if you dont mind.

Thank you so much Gunther  :t

In this test, to copy a large amount of bytes
(.../1027/2062 bytes) the best seems to be memcpy_3

nidud,
        I will add your new procedure
        in the next post.

--------------------------
Results from Gunther
---------------------------
---------------------------------------------
    names used by nidud
---------------------------------------------
memcpy_1  -> is regcopy
memcpy_2  -> is memcpy SSE
memcpy_3  -> is memcpyxmmU SSE

Hi,
        Now, i used crt_memcpy, memcpy_1, memcpy_2, memcpy_3, memcpy_4
        procedures and some SSE procedures.
       
        Gunther, could you post the results of your i7,
        if you dont mind ?
        Thank you.
       
        These are my results.

Hi Gunther,
            It helps, thank you.  :t
            Now i want to test another procedure.         
            Could you run CopyString55, please ?
            Thanks.
       
These are my results.
