Unable to run example AOMP program on V520

Hello

I am trying to run a openMP program on a instance with AMD EPYC 7R32 CPU/ V520 GPU. This is on a AWS shared instance.

I installed AOMP 11.12.0 and the ROCm dependencies.

However, when I try to compile and run the veccopy example under AOMP install folder,

[ec2-user@ip-172-31-42-182 veccopy]$ sudo make run
Makefile:28: AOMP not found at /root/rocm/aomp
/usr/lib/aomp/bin/clang -O3 -target x86_64-pc-linux-gnu -fopenmp -fopenmp-targets=amdgcn-amd-amdhsa -Xopenmp-target=amdgcn-amd-amdhsa -march=gfx900 veccopy.c -o veccopy
./veccopy
[/root/git/aomp11/amd-llvm-project/openmp/libomptarget/plugins/amdgpu/impl/system.cpp:515] Initializing the hsa runtime failed: HSA_STATUS_ERROR_OUT_OF_RESOURCES
make: *** [run] Error 1

I am unable to figure out the meaning of the above error and how to fix it.

Then I modified the Makefile to specify the GPU as gfx1011 (device type for V520) (line in bold),

[ec2-user@ip-172-31-42-182 veccopy]$ grep AOMP_GPU Makefile
# export AOMP_GPU=sm_30
INSTALLED_GPU = $(shell $(AOMP)/bin/mygpu -d gfx900)# Default AOMP_GPU is gfx900 which is vega
AOMP_GPU ?= $(INSTALLED_GPU)
AOMP_GPU = gfx1011 # for the V520 device

The bitcode file for gfx1011 is not available in the rocm install folder.

The same list above shows under /opt/rocm-4.0.0/llvm/lib/ as well.

Here's my rocm install list:

[ec2-user@ip-172-31-42-182 veccopy]$ rpm -qa | grep rocm

rocm-smi-3.8.0-1.el7.noarch

Please suggest how to get the openMP examples to run successfully on the V520 GPU.

Thanks in advance.
