Intel's MKL LaPack vs. ZTRMM: advice needed
Posted: Tue Apr 25, 2006 3:18 am
Hello,
In VASP the GUIDE there is this information:
If the LAPACK is not well optimised, the call to ZTRMM should be avoided,
and replace by ZGEMM. This done by specifying NOZTRMM in the makefile.
I want to use the MPI version of VASP on a Linux/Intel Xeon cluster
(8 CPUs) with LaPack from Intel's Math Kernel Libary (MKL), e.g. in
the Makefile I have:
Is the MKL library "well optimised", or not? Should I use ZTRMM, or not?
Thank you,
R.
