Digital - AlphaServers smash 'Datamation' benchmarks
{Livewire, Worldwide News, 25-May-95}
"If your applications are starving for performance and your uniprocessor
RISC server isn't cutting the mustard," "Datamation" magazine reported in its
May 15 issue, "Digital just might have a the answer to your performance woes."
Citing "...performance that scales from the workgroup to the data center,"
the trade publication reported that the new AlphaServer 8400 5/300 and 2100
5/250 systems recently established new records in Datamation's CPU Benchmark
version 2.0 (CPU2) running under Digital UNIX.
The AlphaServer 8400 systems scored a PPI (Processor Performance Index) of
838, the highest PPI ever recorded. The AlphaServer 2100 system scored a
lower, but still impressive 705, which is also higher than any system
previously tested.
CPU2 is made up of 34 kernels that perform CPU-intensive floating point and
integer operations. A kernel's execution time is divided by the execution
time it took a 60MHz Pentium system to run the kernel, and a geometric mean is
calculated from all the normalized kernel results. The final result is the
PPI, where a 60MHz Pentium has a PPI of 100.
In a second test, to determine the SMP efficiency of the servers,
"Datamation" ran multiple copies of CPU2, up to 64 copies on each server. The
SMP efficiency of the AlphaServer 8400 gave "very good" results. The
AlphaServer 2100 system also performed well, but, as expected, was somewhat
less efficient than the 8400 throughout the range.
"The 8400 is meant for the data center, and if you're looking to replace
mainframe iron, this machine is a suitable candidate," "Datamation" concluded.
"The AlphaServer 2100 5/250 is meant for workgroup applications."
