Stuck on ATS-P GPUs

I found that when the compilation optimization level is O0 (using the compilation script below), the following code will stuck. I think it is related to sycl::stream (line 22-23).

Code

#include <CL/sycl.hpp> using namespace sycl; #define WRAP_SIZE 32 int main(){ sycl::gpu_selector selector; queue exec_queue(selector); int num_blocks=128; int num_threads=256; int size=num_blocks*num_threads; int casBeg=0; int casEnd=2; double * _buff = (double*)sycl::malloc_device(sizeof(double)*size, exec_queue); exec_queue.submit([&](sycl::handler& cgh) { sycl::stream out{ 4096, 128, cgh }; auto sharedmem = sycl::accessor<int, 1, sycl::access_mode::read_write, sycl::access::target::local>(11, cgh); cgh.parallel_for( sycl::nd_range<1>(num_blocks * num_threads, num_threads), [=](sycl::nd_item<1> item_ct1) [[intel::reqd_sub_group_size(WRAP_SIZE)]] { int blkId = item_ct1.get_group(0); int tid = item_ct1.get_local_id(0); if(blkId==0 && tid==0) out<<"inter\n"; _buff[num_threads*blkId+tid]=tid; item_ct1.barrier(sycl::access::fence_space::local_space); }); }).wait(); std::cout<<"finish program!"<<std::endl; return 0; }

Compile and run scripts

# file run.sh echo "compile program" dpcpp -std=c++17 -o project_op1 main.cpp dpcpp -std=c++17 -O0 -o project_op0 main.cpp echo "run project op level-one" ./project_op1 echo "run project op level-zero" ./project_op0

I've reported this to our development team.

Thanks,

Hi,

Since this occurs only at -O0 and on ATS-P, developer is not planning to fix this issue. Hence, I will close this issue as "Wont Fix".

If it happens on other platforms, please create a new thread.

Thanks,
