I was recently asked about how one would go about doing a quick cluster
demo with the following configuration:
a laptop running a TBD version of Linux
a bunch (4-16) of diskless nodes (implying that they need to netboot with
PXE, etc.)
all connected with ethernet..
Seems like something like
There are a few cluster specific sites/blogs. Cluster Monkey
(www.clustermonkey.net), Scalability.org (www.scalability.org), and
probably a few others.

Title: RE: [Beowulf] MPI mysql
It's not going to be as easy as that. You have to use whatever mechanisms for scaling are available within mysql, i.e. Master/slave replication or the more advanced ndb stuff. In either case you probably will need to find somebody experienced to assist you.

That doesn't matter very much, because the harddisk of each Typhoon node
is mounted at a place blocking all PCI-whatever slots. Even, if you

Could some make mysql run over mpich on a Beowulf cluster?

Hello beowulf,
Does anyone know of a website on clustering that has a message forum?
I feel more at home in a message forum than in a mailing list.

If you are going to look into a different MPI implementation,
consider HP-MPI. The choice of interconnect (GigE, Myrinet, IB, and
Quadrics) are all written into it, so you can create a single
(common) operating environment for your programmers. I had a look at
the benchmarks a few months

Thanks.
No I have not tried a different version of MPI to test but will do so.
As for a later version of OpenIB, there is incentive to do so but I
don't know how quickly that can be accomplished.

More memory in your nodes? Not sure what size of queues and such
openmpi allocates, but you could simply be running out of memory if
openmpi allocates large queue depths.
Have you tried an alternate MPI to see if you have the same problem?
