Benchmark comparison of various systems. ----------------------------------------- This test runs the GSIM code, a GEANT based Monte Carlo code for 600 events, which takes about 10 minutes on a PIII. The calculation involved is very CPU intensive, BUT most of this is INTERGER arithmetic. The code is small and easily fits into the systems memory, and I/O requirements are low. Systems tested were a dual PII @ 450Mhz, 2 dual PIII @ 850 Mhz, and a dual Athlon MP at 1 Ghz. One of the dual PIII (improv) is an interactive workstation, all other systems are dedicated computers. Raw results are listed below. A "1job" score is when only a single job was started. A "2job" score is when 2 jobs were running concurrently, the first score is the first job started. =========================================================================== Table I: GSIM Version September 11 2001 600 Events, processing times.

One relatively remarkable thing to note was that the "2jobs" score are not lower than the "1job" scores. Especially Intel systems are known to suffer a performance hit when a second job on the second processor competes with the first for memory bandwidth. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Section II CLOOPS The CLOOPS is the C version of the Livermore Loops benchmark. This benchmark is supposed to test heavily for FLOATING POINT operations. It needs very little memory, and was compiled to run optimized (-O2 -malign-double -ffast-math -funroll-loops) for DOUBLE size variables. The performance of this code depends quite strongly on the compiler and the compiler options. Compiler used was the EGCS compiler version egcs-2.91.66 for RH7.1 systems. "Beans" is RH6.2, which used the same compiler but an earlier version of the GLIB libraries. Results are not quite reproducable from run to run, probably because this code is not optimized for Intel platforms and the relatively poor standard CPU time clock. Several runs are quoted. ======================================================================== Tables2: CLOOPS compiled with EGCS: Slave30: Dual Celeron 300A at 300Mhz, dedicated system, RH 6.2 kernel: 2.2.16-3 1 MFLOPS RANGE: REPORT ALL RANGE STATISTICS: Mean DO Span = 167 Code Samples = 72 Maximum Rate = 181.4268 Mega-Flops/Sec.
