Thank you Junchao, Yes, I am using gpu-aware MPI. Is "-use_gpu_aware_mpi 0" a runtime option or a compile option? Best, Sophie From: Junchao Zhang <junchao. zhang@ gmail. com> Sent: Thursday, February 29, 2024 10: 50 To: Blondel,

<div dir="ltr">Hi Sophie,<br>
PetscSFBcastEnd() was calling MPI_Waitall() to finish the communication in DMGlobalToLocal.
<div> I guess you used gpu-aware MPI. The error you saw might be due to it. You can try without it with a petsc option -use_gpu_aware_mpi 0</div>
<div> But we generally recommend gpu-aware mpi. You can try on other GPU machines to see if it is just an IBM Spectrum MPI problem. <br>
