Re: [OMPI users] Java MPI Bindings in 1.6.x
FWIW: Greenplum is about to release exactly that solution based on OMPI, though it will require the OMPI trunk. Not back portable to v1.6 I'm afraid, but allows you to run Hadoop on any cluster as opposed to requiring dedicated hardware. I can get an early-adopter release for you, if it helps.

Re: [OMPI users] Java MPI Bindings in 1.6.x
Our case is a single user expressing interest, and maybe long term mixing as we explore hadoop options, and would mix MPI+hadoop. I would not go into the effort if it is non-trivial to add it to 1.6.

I don't remember exactly where we got them; the repository might not have been public. I know we (i.e., Ralph) scoured around for quite a while before settling on this particular set. IIRC, we might have gotten this set from our contacts at HLRS, and therefore it might not be on the open web anywhere else. > Is it possible to take the bindings from the dev tree and build them against > the 1.6 stable? If not what mpiJava bindings do you recommend? Officially, we will not be porting the Java bindings to the v1.6 tree (because it's the stable tree -- no new features will be added). That doesn't mean it can't be done, however. I think the hard part was figuring out the build system mojo for it, but that's now been done. If you have users with a genuine interest in using the Java bindings but want to use them with v1.6, I might be able to put up a bitbucket based off the v1.6 branch that includes the Java bindings. It would be great to get some feedback on these (admittedly incomplete) Java bindings. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
[OMPI users] Java MPI Bindings in 1.6.x
I know java MPI bindings are in the development tree, and the FAQ states they are derived from the HLRS bindings (which I can't appear to find online). Is it possible to take the bindings from the dev tree and build them against the 1.6 stable? If not what mpiJava bindings do you recommend?
