Hi, I have read in the user-manual that parallel sparse matrices are stored in the manner that the first n1 rows are stored on the process with rank 0 and the next n2 rows on the process with rank 1 and so on. My question is now, is it possible to store for example the rows 0 to 24 and 50 to 74 on process with rank 0 and 25 to 49 and 75 to 99 on process with rank 1 for a 100x100 matrix with two processes.
Best regards, Stefan
