Zero optimisation is good to start with. So, first of all get rid of the -O2 flag. I guess mpi was compiled and installed in your local directory. So, that is another point to look at. Recommended that the installation procedure be looked at carefully. Did you use intel compiler for mpich installation and are using some other compiler (gcc?) for compiling the program? Possible because of the missing _intel_fast_memcpy symbol. Using the same compiler for mpich and programs will be best. HTH Chetan -- l...@iitd - http://tinyurl.com/ycueutm
