Description:   Linux/Unix of release 2 of BYTE Magazine's BYTEmark benchmark



hi guys
as promises i am opening this thread in order to report benchmarks of different cpus; tests have been performed with app-benchmarks/nbench under a ramrootfs linux (it's possible only for a reduced set of machines, especially for SGI/MIPS machines), and collected in this thread



e.g.
AR7161 @ 680Mhz -> BogoMIPS 479.23 (Router)

What's up with that miserable LU decomposition performance? :shock:

For the mathmatically inclined, the linear algebra pack is available on IRIX:

it may be a kernel issue that causes performances lost, i am not surprised about that for IP30 (octane2), as … i am dealing with a very old kernel that has a lot of things that simply do not work in the right way and we forced them to do the minimal for survival

sooner or later i will try nbench under Irix instead of under linux :mrgreen:
