out-of-core for matrix inversion

Postby gocanal » Mon Sep 07, 2015 11:39 pm

I am new to scalapack. I am looking for the out-of-core implementation for matrix inversion. My matrix can be up to 1 million x 1 million, double complex data type.

I saw http://www.netlib.org/scalapack/prototy ... .outofcore but I am not sure if functions to support matrix inversion are implemented. I understand that matrix inversion can be supported with function dgetrf and dgetri.

It seems that dgetrf/zgetrf is supported (PFDGETRF/PFZGETRF), but dgetri is not supported. is it true ? If there another way to get matrix inversion ?

thank you very much,
