Hi All,
I am trying setup ET on a new cluster (hosted by the Minnesota
Supercomputing Institute at U of Minnesota, Twin Cities). I have been
using the mdb file bluewaters.ini as a template, replacing bluewaters
specs with my specs where necessary. I've attached my mdb file for
reference. I am able to build simfactory using the --machine=mesabi
flag. I am able to run the testsuite with no failed tests (although
several "unrunnable" tests, which I am assuming is ok?). I can submit
jobs, and they seem to run to completion just fine.
However, every time I log in, I am on a different login node, which
triggers an "unknown machine name" error, unless I have previously built
simfactory on that particular node. I have tried to mimick bluewaters'
aliaspattern line in hopes that it would do the trick. But I must be
doing something wrong. What do I need to include in my mdb file to force
the system to recognize that all of the login nodes are on the same machine?
For a bit more background: MSI uses a two step login process. First you
ssh into a login machine. Then you ssh from there into one of the
clusters. The machine I eventually reach is named mesabi, and the login
hosts are named ln000[1-6].
Any help is greatly appreciated.
Thanks,
Eric
