Hello beowulf,
I might be jumping to a conclusion but this new kernel and the sudden
network problems here are fishy. Ubuntu had network issues with every
kernel.
My gateway has flipped itself to 192.168.0.255. It insists on staying that
way too. I have had other issues tonight though.
It is just a

Thanks Benson, these are very useful links. I browsed the Mellanox
guide and it seems the target audience is experts in networking. I
wish there was some quick start guide or Infiniband for dummies book :-)

Thanks John. I believe we purchased the enclosure from HPe with only
hardware support. I am not aware of any support contract with
Mellanox. We are running RHEL 7.5 ( I may have accidentally said it
was Cent OS, but that was a typo )..
I am more the application guy. We have a hardware/netwo

But no-one wants to pay for Bright Cluster Manager, for example.
So the end user gets at best a freeware solution like Rocks, or at worst
some Kickstarted setup which installs an OS,
the CentOS supplied IB drivers and MPI, and Gridengine slapped on top of
that.
Hi Faraz,
Mellanox manuals can be found at:

exact details on your hardware):

Warming to my subject now. I really dont want to be specific about any
vendor, or cluster management package.
As I say I have had experience ranging from national contracts, currently
at a company with tens of thousands of cpus worldwide,
down to installing half rack HPC clusters for customers, and
Chris, I have to say this. I have worked for smaller companies, and have
worked for cluster integrators.
For big University sized and national labs the procurement exercise will
end up with a well defined support arrangement.

Hi John,
I think there is a bit of an inaccuracy given you mention HP. What I have
learned as I am working with a local HP and HPE distributor that for servers
and everything you want to deal with HPE (HP enterprise) where as standard
consumer hardware is bought from HP as they have two distinc
Pleas tell us the history of the overall system.
Was it bought as hardware only from a supplier? Or was it delivered as an
already set up system with operating system, applications, Infiniband
drivers etc?

I suspect that would be set out in the contract for the HP system.
The clusters I've been involved in purchasing in the past have a
You ask some damned good questions there.
I will try to answer them from the point of view of someone who has worked
as an HPC systems integrator and supported HPC systems,
both for systems integrators and within companies.
We will start with HP. Did you buy those systems direct from HP as servers
Thanks. Before I go down the path of installing things willy-nilly, is
there some guide I should be following instead? I obviously have a
problem with my mellanox drivers combined with "user error"..
