The MIT myrinet cluster consists of a gateway node cg01, and sets of cluster nodes, myrinet-3-NN, myrinet-4-NN. Log on to gateway machine cg01.lcs.mit.edu, and unpack the First Code Improvement tar file into a scratch (e.g. /s01/USERID) directory. In the top-level of the unpacked directory execute the command ./runtest.sh. This will submit a job to compile and run the JMC Code L using ESMF.
