Re: Parallel ISCreateGeneral()



OK..so I should be using the aggregate length returned by MatGetOwnershipRange() routine?

Thanks Matt for you help.

IS are not really parallel, so all the lengths, etc. only refer to local things.

Hi all,

Just wanted to know if the "the length of the index set" for a call to
ISCreateGeneral() in a parallel code, is a global length, or the length
of the local elements on each process?

Thanks,

Tim.
