I am wondering how to use ISCreateGeneral(). Assuming I use 2cpus when I run my codes. I use MPI_COMM to create an object of IS using ISCreateGeneral() and an array on a single cpu. how to distribute this IS object on these 2cpus? If I use MatGetSubMatrices() to get different submatrices on different cpus. I am wondering how to create IS object, using PETSC_COMM_SELF? thanks a lot.
