Intel Advisor GPU profiling failed.

Hi Guys,

I installed Intel Advior Beta through OneAPI base ToolKit successfully. Our system is Ubuntu with Linux version 4.15.0. Our GPU is Intel(R) Gen9 HD Graphics NEO. I am using lastest sycl compiler with opencl backend. I want to collect GPU Roofline but it fails.

Here is my command:

advixe-cl --collect=roofline --profile-gpu --project-dir=./advixe --search-dir src:r=. -- ./myexe

Roofline would run analysis twice, survey analaysis and tripcount analysis respectively.

In first analysis, it reports GTPIN warnings as below. What is this?

advixe: Starting command line: advixe-cl --collect survey --profile-gpu --project-dir ./advixe --search-dir src:r=. -- ./myexe Intel(R) Advisor Command Line Tool Copyright (C) 2009-2020 Intel Corporation. All rights reserved. advixe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: advixe-cl -r advixe/e000/hs000 -command stop. OCLC: Attempting to find device type gpu OCLC: Successfully found OpenCL device Device Name = Intel(R) Gen9 HD Graphics NEO Build Options = -D data_t=float -cl-single-precision-constant Build Options = -D data_t=double Verification PASSED: 0 errors advixe: Warning: [Instrumentation Engine]: GTPin: GTPin didn't find any kernels... Exiting without doing anything. advixe: Collection stopped.

In second analysis, it reports device not found as below but obviously it successfully found the GPU device in survey analysis. How could this happen?

advixe: Starting command line: advixe-cl --collect tripcounts --profile-gpu --project-dir ./advixe --search-dir src:r=. --flop --no-trip-counts -- ./myexe Intel(R) Advisor Command Line Tool Copyright (C) 2009-2020 Intel Corporation.

Can anyone give me some help?

Hi Lin,

Could you please run:

advixe-cl --version
dpcpp --version
apt search ^intel-opencl$

and copy the output here?

Also it would be helpful if you shared the OpenCL initialization part of your source code. You can contact me via corporate e-mail (Anton Timofeev) for it.

BR, Anton

Hi Anton,

I've sent you an email for detailed code. Here is the command output.

$ advixe-cl --version Intel(R) Advisor 2021.1 beta07 (build 606302) Command Line Tool Copyright (C) 2009-2020 Intel Corporation. All rights reserved. $ dpcpp --version Intel(R) oneAPI DPC++ Compiler 2021.1 (2020.x.0.0728) Target: x86_64-unknown-linux-gnu Thread model: posix InstalledDir: /nfs/shm/proj/icl/cmplrarch/deploy_xmain/xmainefi2linux/20200728_000000/build/linux_prod/bin $ apt search ^intel-opencl$ Sorting... Done Full Text Search... Done

Actually I found that the second issue is because I cannot collect tripcounts analysis on GPU. I trigger the tripcounts individually, it still reports GPU device not found error. That's so weird.

Thanks,

Lin

I suggest you to install the compute-runtime packages from https://github.com/intel/compute-runtime/releases
