|
|
Does anyone have Gentoo on Sparc's clusterd? Does openmosix work? Is there any clustering software for 2.6.x kernel?
Thx, |

hmmm openmosix-sources are only for 2.4.x, and www.openmosix.org doesn't contain anything about 2.6.x but it says openmosix is only for x86 yet

I found this Web Site
But I don't see anything "so far" that says it couldn't work on sparc hardware?? |

Well, openMosix is about a 50,000 line patch file (to the kernel),
some amount of which is in x86 assembler. So I don't think a sparc
version is in the works for anytime soon.
You might find better information someplace, though. |

Try here: http://www-unix.mcs.anl.gov/mpi/mpich/
I hope this works for you as I'm planning to use it myself when I get around to upgrading the university's student supported Debian Sparc boxes to Gentoo and the 2.6 kernel |

If you want clustering with mpi, lam-mpi works for sparc. You probably want
to use version 7.0.4 (the lam people do not support any 6.xx version
any more); it does work on sparc (see bug 43690). For testing, it will be
easier for you if you build with USE='-crypt' because there are some tricks
for getting lam-mpi to work with ssh.
If you want to use mpich, I know that 1.2.5 works on sparc linux. Configure
it with '--device=ch_p4' Note, however, that sparc linux is not really a
combination that mpich knows about, and it will not interoperate with linux
on other architectures without some rather kludgy modifications. (You can
do it, but you won't like it much.)
PVM works on sparc. I haven't tried it on sparc linux, but I see no reason it
wouldn't work.
If you want to try lam-mpi. you will probably want to poke around on
http://www.lam-mpi.org and grab all their documentation, test suites, and so
on. If you don't know anything about mpi, do want clustering, and think
mpi might be the way to go, you might want to hunt up a copy of
Using MPI-2 by Gropp, Lusk, & Thakur (ISBN: 0-262-057133-1).
Hope this helps,
Ferris |

This is what i've been able to derive from the lam/mpi website:
lam is a user-space daemon for distributing processes across a clustered network. Because of its userspacenessness it's platform-independent, and therefore supports hetrogenous clustering. This is good for me. Is this correct?
I also wondered if anyone had any expierence using lam-mpi, over a heterogenous sparc cluster (some old sparc5s and misc x86 boxes) running nfs. I've heard there's some incompatibility with lam and nfs.
Thanks. _________________ word. |

It supports heterogenous clustering as long as you don't use calls to mpirun
that look like
or similar which say to take the program you are distributing from a specific
location (in this example, from 'here') and broadcast that program file to
every node on which you are running.
I don't know of incompatibilities between lam-mpi and nfs, but that doesn't
mean there aren't any. The lam-mpi mailing lists are pretty active, and
if there are issues with nfs, there are probably discussions concerning any
problems on the mailing list archives (or lam's faqs). (But see the usage notes
in the installation guide, and the user guide generally). |
