PVM test suite and GUI driver are now available. The GUI requires Tcl 7.x and Tk v3.6 to run. The engine performs various API and messaging function tests as well as provides some simple timing and bandwidth measurement routines. The source for the suite and driver are available through this page or by ftp to netlib2.cs.utk.edu in pvm3/pvm_test.tar.gz That's GNUzip for those of you who are compression impared... It should be noted that this software is "very" beta and is in the process of a rewrite by our staff. Please send all comments/questions/bugs/money to mucci@cs.utk.edu. Sincerely, -Phil Mucci
