[Users] setting up an unsupported cluster

[Eric West]

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
