CodeXL CPU profiling
« on: October 17, 2017, 02:49:58 AM »
Hey,

Has anyone tried / or had any success using CodeXL for CPU profiling ?

I've just bought a Ryzen threadripper 1950x, and have installed the latest CodeXL x64 version 2.5.67.

The first thing that strikes me as odd is that it seems to be missing Instruction Based Sampling.
Event Based sampling appears to work, but every single column has exactly the same value in and it makes no sense at all..
Power profiling says it's unsupported (not that it's something I need).

I had great success in the past on intel kit using vtune, but for the life of me I can't make this thing produce any sense... and I'm not prepared to pay again for the crazy price Intel want for vtune etc..

<Raistlin cries a river - whahaaaaaa ! I also want one ! [tantrum]>

PPS: any good open/free/shareware profilers you can recommend ? vtune = $$$

I am noticing that UASM is developing faster now  :biggrin:

You can roll your own  :idea: taking as a starting point this code that is patronized by Intel. ;)

Nice find :)

Pity it doesn't support AMD.. I will try again with CodeXL before giving up entirely on it :)
