The PZGESV subroutine
Posted: Mon Jun 02, 2014 9:36 amHello everybody,
Please I need your help to understand the scalapck subroutine PZGESV.
I am trying to use this subroutine to solve a linear equation system A*X = B where A is a (N by N) matrix distributed as follow : each process has a local matrix Al of size (Ml by N) and Ml isn't the same for the different processes but of course the sum of the different Ml is equal to N.
I don't know if this kind of distribution is allowed with the PZGESV subroutine and if not how can I do it with an other scalapack subroutine ?
Thank you.
