- The LINPACK performance table can be obtained by sending to netlib@ornl.org
- a message saying:
- send performance from benchmark
-
- Here is what I found:
- CDC Cyber 2000V 32 Mflops
- CDC Cyber 205(4-pipe) 17 Mflops
- CDC Cyber 205(2-pipe) 17 Mflops
- CDC Cyber 990E 12 Mflops
- CDC Cyber 4680 9.4 Mflops
- CDC Cyber 875 4.8 Mflops
- CDC Cyber 176 4.6 Mflops
- CDC Cyber 760 2.6 Mflops
- CDC Cyber 175 2.1 Mflops
- CDC Cyber 180-860 2.1 Mflops
-
- The first 486 listed is
- Compaq Deskpro 486/331-120w/487 1.4 Mflops
-
- You can get the benchmarking program and run it on your machine.
