MKL - scalapack - GMRES

Hi everybody,
I am exploring the possibility to use the Intel MKL library for my application, which is a parallel implementation of the GMRES method to solve a linear system of equations (variable coefficient Poisson solver on a structured 3D grid, finite difference method).
I was going to install scalapack but my computer administrator told me we already have MKL installed and *quote* this library has all of the same functionality and also provides wrapper interfaces identical to BLAS,LAPACK SCALAPACK *end quote*.

I am trying to find documentation regarding it, but for the moment I just found the list of the computational routines here:
http://software.intel.com/sites/products/documentation/hpc/mkl/mklman/index.htm

Has anybody used MKL for a Gmres method, or does anybody know about it and can point me to the right direction?

Also, the future plan is to do a multigrid method based on this, but I guess I need to implement the multigrid part myself..

Thanks for your help!

Hello,

If you search for FGMRES Interface Description in the mklmanual (http://software.intel.com/sites/products/documentation/hpc/mkl/mklman/index.htm), you'll find detailed description on how to use it with the parameters to be used.

but if you are looking for a particular routine implementation details, let me know.


Thanks,
Sridevi

Hi,
If you solve Poisson equation with variable solver on structured what do you think about idea to any iterative solver + poisson solver from MKL as preconditioner?
With best regards,
