To TGCM lightning users: I have made several changes to the TGCM Makefile to accomodate the recent OS upgrade to lightning. The models are now building and running on lightning, and you do not have to doctor the Makefile as I suggested in a previous message (5/27). However, you probably still need the following 2 lines in your .cshrc file on lightning: setenv PGI /usr/local/pgi setenv LM_LICENSE_FILE /usr/local/pgi/license.dat Please let me know if you have any problems building or running the models. --Ben
