mpi & domain decomp w multiblock

(Burlen Loring) #1

HI, I have a multiblock dataset that has 9 blocks, When I use N mpi ranks, ParaView is (this is in 5.6) splitting each of the 9 blocks N ways so that each rank is given 1/N the original block. I’d like to disable this feature if possible. Can you tell me how to do so?

Thank you
Burlen

this totally depends on the data producer / reader. ParaView doesn’t care which way or if the blocks are actually split among ranks.

Sounds like it’s a feature of the vtk XML multiblock reader then, and apparently it can’t be disabled with out doing some coding.
