Hi, that use_external_launcher flag has not been used since we published LumiBench. It was only used back when the simulator was first published and only supported the Intel driver. Could you run this in debug mode and show us where the simulator crashes when running GPGPU workloads?

Hi,

I source'ed environment setting with debug and run with LUD application in Rodinia (also used in lumibench paper). Here are the last a few line of output:

I think as long as the program doesn't use any of the ray tracing functions we added, you can set the use_external_launcher flag to true and it should restore the original gpgpusim behavior.

vulkan-sim/src/cuda-sim/vulkan_ray_tracing.cc

Line 120 in dc742fa

bool use_external_launcher = false;

Hi thanks for replying fast,

I also tried to change this flag. but it still doesn't work. log is attched.

Could you also attach the gdb backtrace? Thanks!

Hi, thanks for sharing all the details! There were a few changes that we made to run Rodinia workloads which weren't included with the Vulkan-Sim release. I will sort out those changes and get back to you in a couple of days :)

Hi @lucylufei ,

Thank you so much!
Have a good weekend!

Hi @Yfeng-44, I've pushed the changes to a separate cuda branch. The use_external_launcher variable has been moved into the gpgpusim.config file so please add -gpgpu_rt_external_launch 1 to the configs when running CUDA applications. You can change this back to -gpgpu_rt_external_launch 0 for Vulkan applications. You may also need to modify the -gpgpu_max_simulated_rt_kernels parameter to simulate multiple kernel launches on CUDA applications.

Please let me know if you still encounter any issues.

Hi @lucylufei ,

Thanks for the efforts! I will try the change.

Will close this issue for now, and will let you know if there's any issues.

Thanks!
