Hi,
I'd like to learn if there is multi-threaded and/or parallel (mpi) support for ILUT/FGMRES in intel MKL and/or intel MKL cluster edition. I have read in a few posts that this solver might not be available in parallel for some previous versions, I want to know whether it is available in the latest versions of MKL, and what versions if any support this solver in parallel.
Thank you

Hi,
Currently fgmres/ilut supported in MKL only in sequential mode.
With best regards,

Hello,
is it still true that FGMRES is only supported in sequntial mode? Which to my understanding means that all risks of its application with MPI is up to the user? Hence, there is no iterative solver library in MKL which is intended for usage with MPI?
Thanks in advance

yes, this is still relevant the latest version( MKL 2019) too. FGRMRES supports the sequential mode only and both of mkl iterative solvers are intended for smp mode only.

In the case you really need MPI versions of these solvers, then please submit the Feature Request to the Intel online service center.
