Subject: Problems on Alpha: Too slow

Dear Amberers,

we are compiling Amber 5.0 on the AlphaServer GS140 EV6/525 running
OSF1 V4.0. The compiler identifies itself as follows:

$ f77 -what
         DIGITAL Fortran 77 Driver V5.1-8
         DIGITAL Fortran 77 V5.1-156-3882K

The problem is that the code runs very slowly, approx. 6 times
slower than the R10k computers. Has anyone experienced this behavior?
Is this problem known? Are there ways to fix it?

Thanks in advance.
