can not analysis gpu roofline

hxc — Wed, 30 Sep 2020 18:51:03 GMT

Hello,

Attached is a simple test case. My working environment is (actually a DevCloud node) :

Ubuntu 18.04

Intel(R) Xeon(R) E-2146G CPU with Gen9 graphics

oneAPI DPC++ Compiler Pro 2021.1 (2020.8.0.0827)

Advisor 2021.1 beta09 (build 607056)

I try to compile the program and generate the roofline report:

icpx -fiopenmp -fopenmp-targets=spir64 test.cpp

advixe-cl --profile-gpu -collect=roofline -project-dir=results-gpu -- ./a.out

advixe-cl --report=roofline --gpu --project-dir=./results-gpu --report-output=./results-gpu/roofline-gpu.html

However, the roofline report shows "No floating-point operations detected".

I have written a matrix multiply loop in the test file, so some floating-point operations exist.

Can you help me?

Hello,

Could you please zip your project dir folder "results-gpu" and attach it?

Thanks!

Hi,

Could you please provide GPU driver version?
(dpkg -l | grep zero or dpkg -l | grep opencl)

Could you please print and share collected data via python script:

advixe-python $ADVISOR_2021_DIR/pythonapi/examples/survey_gpu.py ./results-gpu

Hi, I used the command:

advixe-python pythonapi/examples/survey_gpu.py ~/results-gpu

However, an issue occured:

Traceback (most recent call last):
File "pythonapi/examples/survey_gpu.py", line 99, in <module>
data = project.load(advisor.SURVEY)
MemoryError

Attached is the results-gpu folder. Please check it.

Advisor Beta09 have an issue with profiling OpenMP applications with OpenCL runtime.
The issue will be fixed in coming Advisor Beta 10.
Or You can switch to Level Zero runtime.
Sorry for inconvenient.
