Consider the following example
I have 4 block diagonal matrices for 8 processors and I would like to factorize them at the same time.
So I am trying to create 4 contexts, each one with 2 processors.
But it doesn't work
I am calling
I do not know what to setup for CONTXT
If I setup CONTXT=0 on processor 0,1
CONTXT=2 on processor 2,3
CONTXT=4 on processor 4,5
CONTXT=6 on processors 6,7
If I setup all CONTXT=0 on all processors it creates only one context on processors 0,1 but returns CONTXT=-1 and nprow=npcol=myrow=mycol=-1 on other processors
Any help would be appreciated, since I really would like to use several SCALAPCK solvers at the same time for many block diagonal matrices
