[daip] AIPSmark(93) results

[Daniel C. Homan]

Hi,

We recently installed AIPS 31DEC2000 on a DELL Precision Workstation
620.  I'd like to report our AIPSmark(93) from running the Dirty Dozen
tests.  The test completed in a little over a minute and a half for an
AIPSmark of 42.2.  This is with the speed parameter set to 40, although
we got virtually identical results without setting the speed parameter
(I used SETPAR to set it, but I was not sure if there were any
additional steps).

This machine is a dual Pentium III 933 MHz/Xeon system, although only
one processor seemed to be used by the test (I assume this is because
the AIPS tasks were run sequentially and are single
threaded -- but if there is a way to utilize both processors for the
test, please let me know).  The machine came pre-installed with RedHat
7.0, and after upgrading the recommended packages, I installed
gcc-2.95.3 as the default compiler on the system before building AIPS. 
We have 512 MB of PC800 RDRAM installed and four scsi disks (1x18 GB and
3x36 GB).  The 3 x 36 GB disks are configured in a raid 5 configuration
yielding 72 GB of space for user areas and AIPS data disks.

P.S. It is interesting to note that this machine replaces an old Dec
ALPHA 3000 model 600 with 128 Megabytes of RAM.  This old machine scored
an AIPSmark of 3.9 back in March of 1994, and I believe was the record
holder at the time.  I find it amazing that for less than a third of the
cost, our new box can now support two simulatenous AIPS sessions at ten
times this speed.
