Hi,

I'm wondering if CGS iterative scheme can be applied in OOC version of PARDISO. When I try to use it I get
the following error

Factorization completed ...
The following ERROR was detected:   -11

I use MKL 10.3

Thanks,
Alan

Alan,

yes, it the CGS preconditioning should works with OOC mode. -11 error is returned when some problems appear in the process of working with files, e.g. in the case of no space left on device or problems with read / write operations because of algorithm issues. Do you see problem with in-Core mode? What exact update of 10.3 do you use? --Gennady

Gennady, thanks for the reply.

I use latest 10.3.11 version of MKL.

There is no problem when I use in-Core mode.

Regards,
