Hi Ralph,
Hello - and welcome!
Thanks for your previous clarification.
At our organisation ( www.nesi.org.nz) we would like to use MTT for MPI heath check of our clusters.
I actually know some people there! Small world - almost came to work there a few years ago, and have a standing promise to come visit :-) It it okay use MTT, legally, if we sign up to the following agreement.
There should be an address on the form - it gets sent to:
Center for Research in Extreme Scale Technologies (CREST) ATTN: Andrew Lumsdaine, Open MPI 3rd Party Contribution Agreements 2719 E. 10th Street Bloomington, IN 47408 USA
Let us know once you send it and we can proceed - we trust your word that it is "in the mail".
If that is done, how can we install MTT in our clusters? Can you please explain it to me step by step? Or is there any elaborate documentation to get info on it? I have gone through the MTT wiki. It doesn’t explicitly speak about how MTT can be deployed in a stand-alone cluster like ours.
Actually, all you really have to do is clone the git repo for it - all the software is there, and it doesn't require any more installation then setting up a .ini file with the proper configuration. Several examples are included in the repo. I can also share mine with you as it does pretty much what you describe. I have a simple "runmtt.sh" script that executes the tests for me, but it is totally trivial and easily shared. The repo is here:
You can access it any time you like - we don't need the agreement for MTT itself (only for the tests).
We are using Easy-Build to install MPI and other libraries. So we may skip those steps in MTT.We just need to run the tests and collect health reports. From what I understand from the documentation, I have to fetch MPI tests from your svn server each time and run it on our machines.
You actually don't have to do that - you can clone the ompi-tests repo once, and just run the tests from there. It gets updated infrequently, but you can always just do an "svn up" to ensure you have the latest copies. Again, that is an option in your .ini file. Can we collect the results internally and use MTT Reviewer internally to assess it?
Certainly - setting up the database is a bit of a challenge, but once done you can go that route if you like. I'm not the best for those questions, but I'm sure Jeff would be happy to help. He's on travel at the moment, but expected back shortly. Or does it go to a central server outside our organisation?
We encourage people to submit the results to the central MTT repo so we can all see them - helps us to maintain the code. However, some places prefer not to do so for firewall or security purposes, and that's just fine too.
Can you please help us through these queries? Thanks in advance.
We are happy to help get you up-and-running! Please don't hesitate to ask, and I'll send my files along as soon as you are ready.
Ralph

I do it all the time myself - the ini file contains this:
#====================================================================== # MPI get phase #======================================================================
#----------------------------------------------------------------------
[MPI get: My Installation] mpi_details = Open MPI # Leave this parameter blank to # have MTT search your path for an MPI # alreadyinstalled_dir = /your/installation module = AlreadyInstalled
#----------------------------------------------------------------------
[MPI install: My Installation] mpi_get = My Installation module = Analyze::OMPI
Everything else proceeds the same
Hi,
I am just referring to the following previous query at MTT forums, because I too has a similar requirement.
----------------------- I want to skip the MPI Get and Install phases, and simply point MTT to
my pre-built/installed Open MPI. Can this be done

The reply mentioned that this functionality was in your TODO list. Have you implemented it in anyway at all?
We are running a HPC cluster and we use easy-build to make our modules (including MPI) available to our users. So we may not want to Get, Install, Build steps at MTT, but the Run section to test the stability of the systems. Is it possible to do?
Thanking you in advance, Jaison Mulerikkal p: +64 9 923 2194 (internal ext: 82194)
