Updated crunch_mpiGraph
At first, somewhere the standard of naming node is nXpY, so regex has been changed. At second, there is no package with name hostlist_lite on metacpan. Seems deprecated.
Thanks, @abrekhov . I'll take a look.
On your second comment, the hostlist_lite.pm is included in the repo.
https://github.com/LLNL/mpiGraph/blob/master/hostlist_lite.pm
The crunch_mpiGraph script should find and load this hostlist module so long as the crunch script is executed from within the same working directory as the hostlist_list.pm file. If you'd like to run the crunch script from a different directory, I think one can add a use lib entry to point to the directory containing that file.
Do either of those work for you?
