I know from bitter experience that the intel IBM compilers are not compatible with gcc-compiled libraries - if you are going to use the IBM compiler then you have to recompile EVERYTHING.
We ended up going with compilers from the Portland Group for that very reason.

In my case the program was CNS (crystalllography and NMR system). A colleague had compiled this and the NMR parts indeed to run much faster. However, for the crystallography programs, suddenly my space group operators no longer formed a symmetry group. I decreased the optimization levels to 0 but the problem did not go away. I've compiled this program with GCC/g77 v. 3.1 and MIPS compilers and others have used probably a half dozen fortran compilers on various unix flavors without this sort of problem. I'm not an expert, but it seems like there might be major but subtle problems with the IBM fortran compiler even if you do get it to compile your code. FWIW these are the optimization flags that were used for the initial compile: -O5 -qarch=ppcv -qtune=auto -qalign=4k -w -qfixed=132 HTH, William G.
