Hi, all I use SLEPc as part of my program, which means I compile it as .so library.
I want my program work like this: execute serially, reach Point A, parallel solving, then serially again. I know I could use mpirun -np 4 in terminal to call the whole program, but this will let the serial part be executed 4 times. What I want is only call mpi at the eigensolving part. Is there any function that could achieve something like that? Thanks a lot.
