Can't run ospMPIDistribTutorial on Windows with Intel oneAPI Tools #496

Closed smallling closed 3 years ago

smallling commented 3 years ago

I compile ospMPIDistribTutorial.cpp and ospMPIDistribTutorial.c with Intel oneAPI Tools and run them with command mpiexec -n 2 ospMPIDistribTutorial.exe but failed:

Exception thrown at 0x00007FFC812F14E9 (ospray_module_mpi.dll) in ospMPIDistribTutorial.exe: 0xC0000005: Access violation writing location 0x0000009D854963C0.

How can I fix this?

johguenther commented 3 years ago

Hmm. Do other MPI tutorials work, like the ospMPIDistribTutorialSpheres?

smallling commented 3 years ago

OspMPIDistribTutorialSpheres and ospMPIDistribTutorialVolume failed too. Only ospMPIDistribTutorialReplicated succeeded.

I think these are probably due to the same issue as #495, but I haven't tested out my fix on Windows yet. I'll take a look there to see if that fixed it, or what else might be going on.
