Yes, it is possible, I have compiled it on AIX previously. Unfortunately I don't have ready arch.make, but I can give you some hints. In general just follow the normal procedure of compilation, and pay attention to the following. If you have parallel environment installed (poe) you should use mpfort as the compiler (FC). It automatically generates parallel code and links the required libraries for parallel use. Don't forget about --enable-mpi. Use the -lessl library for blas, it gives significant improvement over netlib blas. ESSL is a standard library must be installed on IBM system. Good luck, Bartek
