[petsc-users] MatMPIAIJSetPreallocation deadlocks

[Edoardo alinovi]

Hello Petsc friends,

Hope you are all doing well.

Today I was doing a simulation (27Mln cell on 64 cores) and I came across
an issue. Indeed, I am  deadlocking somewhere in *MatMPIAIJSetPreallocation.
D*o you have any clue about the reason for this? Any suggestions to track
this down?

Many thanks,

Edo
