Open Source Code Finds Way into Microsoft Release

linumax tells us eWeek is reporting that Microsoft, for the first time, has included open source code in the release of one of their products. The Complete Cluster Edition of Windows Server 2003 will be including the Message Passing Interface (MPI) library. From the article: "MPI is key middleware that was designed by a consortia of all the supercomputing vendors in the 1990s to allow the easy portability of code. It abstracts away things like low-latency interconnect, and our focus is making it super easy for ISVs to move their code."

    I've done quite a bit of MPI programming using the MPICH and MPICH2 implementations. MPI itself is nothing more than a specification that addresses issues with sharing memory between processors, whether they are in the same 'box' or connected through some fabric like Ethernet or some of the high-speed interconnects.

    The specification is focused mainly on the syntax of the API to make Fortran, C, C++, and Java (?Not sure if Java is actually part of the spec yet) codes compile and operate smoothly across different MPI implementations like MPICH or LAM, to name a couple (I've never run into an MPI implementation, personally, that has screwed with the standard. All my codes have always compiled and functioned cleanly across multiple implementations (after extensive debugging, of course ;-) ).

    MPICH and MPICH2 provide many different "drivers" to allow its use over 100Mb/GigE ethernet (ch_p4), Myrinet (provided by Myricom, ch_gm), Infiniband, ccNUMA or NUMA-like systems (ch_shmem, or lock-free ch_shmemlf), and drivers for globus systems.

    With interconnect fabrics like ethernet and low-latency Myrinet and IB, Message passing typically involves passing actual data between hosts across this fabric and the ch_p4, ch_gm drivers handle this transparently (this part of the setup, selecting the driver, is a function of your Administrator and not the developer). On large memory SMPs, MPI may pass addresses or references rather than the actual data, taking advantage of the fact that the hardware is designed to allow any single CPU to address any region of memory rather than flooding the memory bus with unnecessary transactions.

    Take parallel video rendering for example, where we might be simply gzipping each frame... on a cluster-style interconnect, each host must have a copy of the frame it is operating on so it must be passed along the interconnect to the host before work is done (or it can be read by each host from the original file, if that file is shared across the cluster or copied to each node. This becomes very I/O bound and suffers from the slowness of hard disks). On an SMP, a pointer to the beginning of that array may be passed to the thread or process trying to do the work, while the segment of that video is stored in RAM.

    Being able to share memory in such a way allows fine-grained calculations like very-large-matrix operations over slower interconnects AND SMPs (though your performance on the slower interconnects will suffer because of the bandwidth or latencies induced by the interconnect).

    As well, MPICH at least, provides excellent support for debugging parallel applications through the mpirun_dbg.* commands. It uses your favorite debuggers whether they be gdb, ddd, dbx, or totalview.

    MPI in a nut shell, provides for the easy creation of multiple process threads and facilitates the sharing of data between each thread to enable parallel processing regardless of how your CPUs and memory are connected. Don't know anything about TIBCO though, nor have I ever heard of it... Sorry if this was too much or too little info. I'm not really aware of the average /.er's experience with such things.

  36. MPICH2? What interests me... by jd · · Score: 3, Informative
    ...is WHY they would choose the version of MPI that is regarded as a great reference edition but not that good for serious work. MPICH2 does not support shared libraries under Microsoft's C compiler or under Windows (MPICH2's docs) or external data representations. Their version of ROMIO also hangs when using MPI threads.


    (Also, MPICH sucks when used with multiple devices - you have to compile it with the device(s) you're using, and can only configure it for one device type at a time. So if you're planning on using a mix of Infiniband, Globus and Ethernet, forget it. It won't work.)


    Probably the best MPI library out there is Open MPI, which supports the MPI2 standard, supports MPI threads and progress threads, is much more optimizable for different platforms and was developed by groups ranging from Los Alamos Laboratories (yes, the nuke place) and the LAM/MPI development team.


    Ok, you have a choice between two implementations. One is slow, has a poor release cycle and has been forked numerous times (MPICH, MPICH2, MP-MPICH, Globus MPICH, GAMMA MPICH and MVICH are all forks off the same code-base). The other is partially written in assembler, is developed by a broad consortium of MPI experts and is unlikely to fork as the maintainers are really good about integrating new code. Which would you pick?


    I am also concerned about Microsoft's history of "Embrace and Extend' - are they planning on breaking the MPI-2 specifications for their own purposes? I can't see any value in them doing so, but I don't see any value in 'Embrace and Extend' anyway.
