Scali breaks 300 MByte/s barrier for MPI in Itanium clustersOslo 27 August 2001 Scali has enhanced the performance of Scali's MPI, ScaMPI, hosted on Intel Itanium servers and broke the 300 MBytes/s barrier. The new release of ScaMPI, to be included in the upcoming SSP 3.0, improves performance on certain transfers in excess of 40%, compared to previous releases.
"To our knowledge, this the first time Intel Itanium servers can be
clustered into balanced systems. Previous clustering efforts of
Itanium servers suffered from an imbalance between the tremendous
computation power of the EPIC architecture, compared with the
bandwidth of the interconnect. Today, with our MPI implementation,
ScaMPI, on top of Dolphin's SCI interconnect,
application-to-application performance in excess of 300 MBytes/s is
achieved, yielding a balanced cluster", says Håkon O. Bugge, CTO of
Scali AS.
A pre-release of Scali's SSP 3.0 is available for download from

The development of Scali Universe for Itanium has been supported
by Fujitsu-Siemens Computers and
Intel. Fujitsu-Siemens incorporates Scali
technology in their own branded products on an OEM basis.
