<P><FONT SIZE=2>Thanks guys for your help. I managed to get passwordless rsh & ssh to work. I upgraded to mpich2 as I got more familiar with mpich1 and mpich2 is running fine.<BR>

Just curious questions:<BR>
<BR>
1. If one had an existing project, say a GTK or QT application with Makefile and everything. If one wanted to incorporate MPI into this project, one would just replace (in the Makefile) the 'GCC = gcc' to 'GCC = mpicc', 'GXX = g++' to 'GXX = mpicxx', and also maybe include some MPI lib paths to the INCPATHs? Is this how one can convert normal projects into projects incorporating MPI calls?<BR>
<BR>
2. If one had an existing C MPI program. What would be the side-effects of using the mpicxx to compile C code? Is it strict for one to use the MPI:: classes opposed to MPI_ C functions.. when force compiling under C++?</FONT></P>
