| AMD Athlon, AMD
Opteron, ... (64 bits) |
Linux SuSE 9.0 and
above |
WIPL-D Pro kernel
(GUI not supported) |
Cluster version of WIPL-D Pro is also
available. The performance was measured on a cluster consisting of
Intel Pentium D CPUs, running Red Hat Enterprise Linux, where it
achieved around 0.75 parallel efficiency. This means that on a
8-node cluster, the software ran 6 times faster than it would on a
single node.
Memory Requirements
On 64 bit systems, it is possible to
use more than 2 GB of RAM for calculations, thus it is possible to
solve problems with more than 15000 unknowns in-core.
RAM
requirements consist of a fixed amount which is about 400 MB, and an
additional amount which, for various numbers of unknowns, is
given in the table below. Recommended minimum for the professional edition of
WIPL-D Pro is 1 GB
RAM and 200 MB hard disk space.

*RAM [Mb] = 8*N*N (in thousands)
for single precision. For double precision the requirements are
doubled.
