[Vagnekman-users] Software News for Ekman

[Michael Schliephake]

Dear Users,

I would like to inform you about several news with respect to available 
software on Ekman:

   1. Intel-MPI on Ekman
   2. AMD Core Math Library on Ekman

1. Intel-MPI on Ekman
=====================

Last week has been installed the latest release of Intel-MPI Version 4.0 
Update 3. The module name is: intelmpi/4.0.3

This release contains also the more recent Hydra process manager with 
extended possibilities to define the process mapping compared to the 
traditional application start with the mpd daemons. Don't hesitate to 
contact me in the case that your are interested in it and need support for 
it.

With respect to the performance: The performance of Intel-MPI is over wide 
ranges of message lengths similar to MVAPICH2 1.7 that is also available 
on Ekman.

MVAPICH makes use of an improved implementation for communication between 
MPI processes within a single node. I had informed you about this library 
in the previous news mail. The overall performance of MVAPICH2 1.7 is 
therefore higher than for Intel-MPI. To see a simple benchmark you could 
look at

2. AMD Math Core Library (ACML) on Ekman
========================================

ACML is an implementation of BLAS and LAPACK especially for AMD 
processors. The PDC webpage provides usage information

Again, don't hesitate to contact me in the case interest or need for 
support.

The performance of the BLAS routines is very good. For a benchmark of 
DGEMM please look here
