[Paraview] Crash using openmpi with more than 4 processes

[Berk Geveci]

Hi Bart,

Any chance you can attach with a debugger to one of the nodes that crash? It
is hard to tell what is wrong from the errors you posted. We have definitely
run ParaView with OpenMPI with 4 core and more. Also, what do you mean by
"simple VTK file"? Small file? Big file?
