Learning Parallel Programming --- from shared-memory multi-threading to distributed-memory multi-processing

Academia.NET — Tue, 19 Aug 2008 04:05:42 GMT

We're working with Microsoft to develop several tutorials introducing developers to high-performance

re: Exploiting Data Parallelism with OpenMP, MPI and Microsoft HPC Server 2008

Joe Hummel — Tue, 08 Jul 2008 03:15:48 GMT

Someone asked "what do I need to install for the tutorial?" To work with OpenMP, nothing is required other than Visual Studio 2005 or 2008.

To work with MPI, you need to install either "SDK for Compute Cluster Server Pack" or "SDK for HPC Server". The tutorial assumes the SDK for HPC Server, the latest version of which can be downloaded from http://connect.microsoft.com --- you have to signup for the HPC Server beta program. Alternatively, the SDK for CCS Pack is freely available on the internet, just search. This will also you to build and run the MPI applications; you'll need to configure Visual Studio differently, but the differences are obvious (C:\Program Files\Compute Cluster Server\...).

To interact with a cluster as discussed in the tutorial, you should join the beta program for HPC Server, download HPC Server Pack, and install.

Cheers!

Thanks so much for the response, I will try your recommendation and see how it goes :)

Hi Christian. You are correcxt, support for MPE is currently not available in HPC Server 2008, and it appears it has been dropped from the product --- it is being replaced by Event Tracing for Windows(ETW), which is a better technology in the long run given it's deep integration with windows (and not just MPI).

But in the short run, the problem with ETW is that there's no GUI visualizer for the trace, i.e. no equivalent to Jumpshot for visualizing the trace info. Tools are coming, but as of today, nothing is available. Right now, you can capture an ETW trace via "mpiexec -tf tracefile ...", then covert that trace to OTF (open trace format). But then there's no way to view the OTF file, at least not on Windows (all the tools are UNIX-based).

So if you want to do tracing today, what I recommend is that you download the updated 64-bit MPE library, drop it into the same directory as msmpi.lib, link against it (instead of the msmpi.lib), and run the .exe on your cluster. Then grab the .clog file, download back to your dev machine, and use Jumpshot to convert to .slog and view.

In other words, MPE still works, it just doesn't ship with HPC Server 2008. Cheers!

Hmmmm....actually it seems like this is not supported in the current build. I ran the app and got no clog2 file at the end nor the message that is mentioned in the lab. I think you mentioned something about the possibility of this being dropped.

Thanks for the post Joe. I am running the Tracing lab and ran into this problem (I was in your class in the Redmond Airlift a while back) I googled msmpe.lib and your post came up first.

On a later internal build I am using, the library is not being included anymore. With your library, I was able to build the binary.

Very Cool

Very cool. One note. I had to add "default" to it as in Properties.Settings.Default.mysetting

Awesome though, thanks for the post.

Oops, thanks Mike, getting my units wrong. How about I update the original post? Thanks!

I'm glad you enjoyed the talk. The only correction I'd make in your summary is that optimized, compute-intensive code needs 16-24GB/sec bandwidth to memory (not GHz).

Hi Joe,

What is the status on part2?

Paul,

I know this is a long time after your issue was raised... the way to prevent the validation triggering when exiting the app is to set the "CausesValidation" of the form to false.

The document is well written Joe. It is a great overview of LINQ. You should write a more indepth book on LINQ in the same style.
