Subject: [Beowulf] new release of GAMMA and MPI/GAMMA
Hello,
this is to inform you that a new release of the Genoa Active Message
MAchine (GAMMA) is available for download at the site
www.disi.unige.it/project/gamma/
In addition to numerous bug fixes, this release also provides support
for the Broadcom ``Tigon 3'' Gigabit Ethernet chipset. This is not yet
fully tested -- more tests at end of vacations -- but I was able to run
a ping-pong benchmark. Compared to the Intel PRO/1000, the back-to-back
latency of ``Tigon 3'' seems quite disappointingly high (~21 usec, to
be compared with the 6 usec achieved by the Intel PRO/1000). I think
the ``Tigon 3'' may have inherited a slow design from its ancestor (the
``Tigon 2'' found on the old Alteon AceNIC).
I've also put out (two weeks ago) a new release of MPI/GAMMA, available at
www.disi.unige.it/project/gamma/mpigamma/
based on MPICH 1.2.7 .
Work in progress: support for Flat Neighbourhood Networks (FNN).
This is almost done; we will test it ASAP (the code is already inside this
release, but dormant).
Any feedback will be appreciated. Thank you, and regards,
Giuseppe Ciaccio http://www.disi.unige.it/person/CiaccioG/
