They replace the Impact series machines, so this will figure prominently in your machine recommendations for CAVE developers. Also, below is some info on the SGI Origin 2000 I recently received from Los Alamos. Its a seminar there (which I am clearly going to miss... they are a bit far away) about initial benchmarking studies on the O2k. It indicates that the memory subsystem on the O2k's are *much* faster than on the power-challenge racks. This is something that we have been finding as well. -john --- Forwarded mail from Harvey Wasserman Date: Tue, 28 Jan 1997 08:39:49 -0700 To: firstname.lastname@example.org From: Harvey Wasserman Subject: Seminar This Friday Cc: email@example.com "Preliminary Performance Study of the SGI Origin 2000" Olaf Lubeck, Yong Luo, Harvey Wasserman Scientific Computing Group (CIC-19) Friday, January 31 CTI Conference Room 1:30 PM Abstract: We have tested several core- and ASCI-related benchmarks on *single processors* of the SGI Origin 2000 system and found that the Origin is faster than single processors of the Onyx systems by factors of 20% to 370%. Since both systems use the identical processor (an R10K running at 195 MHz), the sole difference in performance comes from the improved memory systems in the Origin 2000. In this seminar, we explain our results. Additionally, we found that the MIPS R10K hardware performance counters can be very useful in understanding a code's performance and we discuss this particularly useful capability. ---End of forwarded mail from Harvey Wasserman
