We are not happy with the Cyber 205's performance. After spending about 20 hours on the code for this one program, I managed to reduce the execu- tion time by 25%. The Cyber 205 was still 5 times slower than the unop- timized code for the Cray 1 out on Lawrence Livermore. This is so slow, that we cannot use the Cyber for anything useful. We do have some time on the Cyber left this month, which I will burn up running an infinite loop, or something like that. I don't know if this has anything to do with the Cyber having virtual memory. -- Samuel A.
