The bh program hangs

[zjin-lcf]

Running the SYCL program, after migrating the Cuda example (https://github.com/zjin-lcf/HeCBench/tree/master/bh-cuda) with SYCLomatic, hangs on an NVIDIA V100 GPU. Thank you for your investigation.

Output of running the Cuda example:

./main 100000 100 ECL-BH v4.5 Copyright (c) 2010-2020 Texas State University configuration: 100000 bodies, 100 time steps Total kernel execution time: 4.7116 s

@zjin-lcf have you tried it on cpu device with small configuration, like "./main 10 10"? on my machine, on cpu device "./main 10 10" run passed.

The program passes on a GPU for small configuration. Thanks.

@zjin-lcf I have reported this issue to SYCL compiler team to locate the root cause and wait for their feedback.

Thank you for reporting the issue for me. I find that another SYCL program also hangs after migrating the Cuda program. https://github.com/zjin-lcf/HeCBench/tree/master/columnarSolver-cuda

@zjin-lcf these it no further action needed in SYCLomatic side, so I close this issue.
