Up: Dual Processor Nodes for
In order to test the efficiency of dual nodes we can employ tests
from the Beowulf Performance Suite (BPS) (http://www.plogic.com/bps).
We used two motherboards:
Both the Intel V6 (icc and ifc) compilers and the GNU V2.96 (gcc and
g77) were used to compile the programs. Information about the test
programs and the compile arguments can be found in the NAS suite in
the BPS package.
- Tyan 2762 with dual Athlon MP 1600+ (1.4Ghz) processors, 2 GByte,
RAM, running kernel 2.4.20
- Supermicro P3TDL3 with dual Tualatin 1.26 Ghz processors, 2 GByte
of RAM, running kernel 2.4.18
A simple script has been written to run the tests and calculate the
speedup for the NAS test suite. The NAS test suite is compiled for
one node using test size A. The script was run three times for and
the results were averaged. The compiler can be changed by editing
the ``run_suite'' line in the script.
