There are four makefiles: 
1) make.aix for IBM p655 and 690
2) make.bgl for IBM Bluegene/L
3) make.ch_gm.gnu for Linux Cluster Gnu compiler
4) make.ch_gm.intel for Linux Cluster Intel compiler
5) make.katana.pgi for Katana Cluster Portland Group compiler
   This is the system default compiler
6) make.katana.gnu for Katana Cluster GNU compiler
   Run the following command before running "make":
   katana % setenv MPI_COMPILER gnu

To compile and link:
system prompt % make -f make.X where X is one of the above suffixes

To run program interactively:
katana % mpirun -np 4 example1_2
twister % example1_2 -procs 4

cootie % must run in batch    (linux cluster)
lee % must run in batch       (bluegene)

Go to scv.bu.edu for detail instructions on compiling and running.
