Hi all, I’m trying to profile the following piece of Julia code, taken from ProfileView.jl , using the external Intel VTune Profiler . Concretely, the code is # vtune.jl function profile_test(n) for i = 1:n A = randn(100,100,20) m = maximum(A) Am = mapslices(sum, A; dims=…

[image] christianl: Although I am not quite sure where this bug report would belong to. Is it the LLVMBuilder repository or the BinaryBuilder.jl repository or the julia repository? I’m not sure. I’d go with JuliaLang/julia for now.

@giordano Maybe you can point us to the right repo here?

LLVM nowadays is built in Yggdrasil

Unfortunately building with USE_BINARYBUILDER=0 in cygwin on Windows fails for me, so I can’t get it to work. I’m wondering whether compiling LLVM with LLVM_USE_INTEL_JITEVENTS would be safe as a default (does it come with a performance penalty or something similar?) I opened an issue to discuss wh…

I think this already was the intention, but fails due to a typo of using USE_INTEL_JITEVENTS instead of LLVM_USE_INTEL_JITEVENTS (which is why the pre-build-cmake log contains this warning)

Not adding anything to the discussion. Using Intel VTune with Julia is impressive! Its something I though about recently. I hope to get hands on with some bigger systems soon so could help with this. Also Yggdrasil was the original Linux distribution on floppy disks. I thought it was long dead. Is …

[image] johnh: I thought it was long dead. Is the Julia builder related in some way? No

With the latest VTune, I also need to set the following environment variable to see the JITed codes showing up in the profile: INTEL_JIT_BACKWARD_COMPATIBILITY=1

I tried to work on Intel VTune profiler with, but I did not know how to connect it to Julia (run via VS code). Any step-by-step documentation for it? or could anyone help me in this please ? Thank you very much!

Played around this morning with it. ENABLE_JITPROFILING=1 INTEL_JIT_BACKWARD_COMPATIBILITY=0 I see: [image] With ENABLE_JITPROFILING=1 INTEL_JIT_BACKWARD_COMPATIBILITY=1 I see: [image] This is on Intel VTune 2022 and Julia 1.9 So the biggest annoyance is that it doesn’t automatically find…

Julia 1.9 and above will have VTune support enabled by default.
