Hi,
I'm getting an error related to memory for test_fwd_lrn
I increased the memory size from 4GB to 512GB I got memory size issue : "out of
memory".
build/GCN3_X86/gpu-compute/gpu_compute_driver.cc:599: warn: unimplemented
ioctl: AMDKFD_IOC_SET_SCRATCH_BACKING_VA
build/GCN3_X86/gpu-compute/gpu_compute_driver.cc:609: warn: unimplemented
ioctl: AMDKFD_IOC_SET_TRAP_HANDLER
build/GCN3_X86/sim/mem_pool.cc:120: fatal: fatal condition freePages() <= 0
occurred: Out of memory, please increase size of physical memory.
But once I increased mem size to 1024GB, 1536GB,2048GB I'm getting this DRAM
device capacity issue.

Smaller number of CUs like 4 also have same type of error.
Is there a regression script or regression log for DNNMark to show mem-size or
configurations that are known working for DNNMark tests so
I can use same setup to run a few DNNMark tests?
Only test_fwd_softmax, test_bwd_softmax are working for CUs from
{4,8,16,32,64,128,256}
Thanks,
David
