Running decomposePar / reconstructPar as parallel apps?
 
Hi,

Perhaps this is a stupid question, but I excel at those :)

Are decomposePar and reconstructPar parallel capable? What I mean is, can these programs successfully be run using OpenMPI or similar across multiple processors to speed the decomposition / reconstruction times for parallel cases?

Again, sorry if this is a silly question or if it could be answered by looking at the source of those programs--not a developer, just a tool-user in this case.

Hi!
They are not parallel, but you could consider using redistributeMeshPar, that does work in parallel.

psuedo-parallel usage of reconstructPar
 
I wrote a basic bash script for running reconstructPar in pseudo-parallel mode as describe in this post. This is only useful if you need to reconstruct a large number of time directories from a transient run.
