What paradigm of parallel processing is FGMRES designed for? SPMD or MPMD ?
Is it possible to run FGMRES in parallel in the Single Program Multiple Data paradigm?
I intend to partition my matrix into n parts and then invoke FGMRES sequentially in each of the n processors (as using the parallel flag took more time than the sequential run for the example routine). Does it make sense to do this? Are there other smarter ways of dealing with this?
