Can any application profit from clustering? RRS feed

  • Question

  • Hi.

    We have a number-crunching app that takes weeks to finish its calculus on a standard corei7 processor.

    Would that app be compatible to HPC? What requirements are there?

    Our developers here dream of simply installing a cluster of two or more computers with the HPC pack and hope the app would utilize the processors of all machines simultaneously. Is that anywhere next to realistic?

  • Hi Ronald,

      You need give more information on how your number-crunching apps work. A few ways to parallel your app:

    1. Multiple runs for your application on mulitple machines. Think of a movie transcoding work, usually you do with below on one node:

               TranscodeApp.exe <targetMovieFile> <OutputFile>

    Now with HPC Cluster, you need start multiple instance of transcode but each targets part of the MovieFile

              On Node1: TranscodeApp.exe <targetMovieFile>.<Part1> <OutputFile><Part1>

              On Node2: TranscodeApp.exe <targetMovieFile>.<Part2> <OutputFile><Part2>

              On NodeN: TranscodeApp.exe <targetMovieFile>.<PartN> <OutputFile><PartN>

    And the last task is to merge the outputFile together.

    2. If your application can run on mulitple nodes, just start the application in the cluster

    If you can provide more details of your workload and how your application works, I may provide more appropriate suggestions.

  • Thank you.

    The developer is absent but I guess we can reply tomorrow.
