I don't really use FORTRAN, however, I have to read/write FORTRAN code sometimes.

g77 compiles slow when libs are on NFS
When I was compiling a very short FORTRAN code, it took 5 min. I found this link described the similar problem with PISA at PHENIX: http://www.phenix.bnl.gov/phenix/WWW/simulation/pisa99.html
The reason is possibly that the NFS write fixes for the Linux kernel versions are not installed. The solution is to copy your code to a local disk and put a symbolic link to your libs at your local disk.

Standard input is logical unit 5 (also Fortran 95 unit 100) Standard output is logical unit 6 (also Fortran 95 unit 101) Standard error is logical unit 0 (also Fortran 95 unit 102)
