  • Blog Post: Accelerating Excel by Parallelization

    Note that Excel 2007 is able to use multiple threads to parallelize calculations on the workstation. Previous versions were not. When you hit “recalculate”, Excel will identify independent areas in your spreadsheet and allocate computations in those to separate threads. There are as many calculation...
  • Blog Post: Upgrading to HPC Server 2008 RC1

    Well, there is no upgrade path, so the quickest way is to re-image. Download the RC build of the HPC software from connect.microsoft.com. If you have Infiniband cards, download the latest WinIB-ND drivers (1.4.0.2577) from http://www.mellanox.com.    1. Re-image the head node and install the latest HPC...

We’ll take you on a tour of this new version of Windows Compute Cluster Server, highlighting the major advancements in deployment, management...
  • Blog Post: Low Latency Links

    Low-latency links are important for message-passing (MPI) applications. Typically several instances of the same MPI process will run on different nodes and depend on data passed from other nodes to complete their computation. Latency is therefore one of the performance-limiting factors to be taken into...
  • Blog Post: Deploying Compute Cluster with WDS

    I found a good article by John McRae on deploying Compute Cluster with Windows Deployment Service here. Although we shipped WDS in Windows Server 2003 SP2 and we use in compute cluster pack SP1, we use it in legacy (RIS) mode. This article describes how to exploit full WDS for deployment. Image...
  • Blog Post: HPC Schedulers

    The scheduler is the core of a high-performance computing cluster: -           It allocates computing resources to the jobs that are submitted to the cluster. -           It maintains the status of those jobs to ensure orderly completion or termination. We provide a scheduler with the Compute Cluster...
  • Blog Post: Computing Utilities

    So, imagine this scenario: you have a rack full of servers that hum along at 20% of capacity, performing "mundane" tasks. Wouldn't it be nice to harness at least part of that remaining computing power for your batch calculations? Wouldn't it be nice to save some money by not having to expand that costly...
  • Blog Post: HPC in Action - Bioinformatics

    Ever played with the "game of life"? Well, here's an example of the real thing: HPC used to study evolution and cellular dynamics. Bioinformatics is an interesting - if unusual - field of application. Computation and visualization go hand in hand, as one is required to make sense of the other. In this...
  • Blog Post: UK HPC User Group Meeting

    The UK HPC user group is meeting in London on June 26th, for what promises to be an interesting day at the Imperial War Museum. This meeting is intended for customers, partners and developers to “meet and mingle”, compare notes and provide Microsoft with direct input into our product and offerings. ...
  • Blog Post: 4x4 and other quick tips

    I've recently been involved in a simple benchmarking exercise. Here are a few quick "rules of thumb" that have helped me: - 4x4 A PCIe 4x slot is supposed to have 4 lanes capable of 250 MB/s each, for a total of 1 GB/s. An Infiniband SDR 4x card has 4 channels clocked at 2.5Gb/s, so a simple rule of...
  • Blog Post: Which topology?

    When you set up a Microsoft compute cluster, you have a choice of five supported network topologies: 1. All nodes on public network only 2. All nodes on public and private network 3. Compute nodes isolated on private network 4. All nodes on public, private and MPI networks 5. Compute nodes isolated on...
  • Blog Post: Free Software from Microsoft? I cannot believe it!

    But it is true! We have about 20 not-for-resale copies of Windows Compute Cluster Server 2003 SP1. If you want one, please register as a community member on windowshpc.net and send a note to volker.will(at)microsoft.com. The license terms will allow you to install 1 head node and up to 10 compute nodes;...
  • Blog Post: HPC Server 2008 webcasts - again!

    Hello again, I'll be doing a series of webcasts soon, hopefully on the feature-complete beta 2 of HPC Server 2008. They will be mostly demonstrations, with a few slides for those concepts that are not evident in the software. Here is the schedule (all times are PST): - 5/9/2008 08:00 AM : Windows HPC...
  • Blog Post: Infiniband on HPC Server 2008 - again

    After I published a document about the installation of Mellanox Infiniband on Server 2008, I have received some good feedback that deserves sharing. Note that: The WinIB 1.4 beta available for download today on Mellanox's web site does not work with the HPC Server 2008 March CTP. We are working with...
  • Blog Post: A Hybrid OS Cluster Solution

    Thomas Varlet, of Microsoft France, and Dr. Patrice Calegari, of BULL SAS, have written an excellent paper on how to build hybrid clusters, i.e. clusters where 2 or more operating systems can be run at the same time. It is recommended reading, in my opinion, for those of us who use both Linux and Windows...
  • Blog Post: More Infiniband tips

    So, you've installed your infiniband cards, but got limited performance improvement for your MSMPI application. Before you look at the code again, you may want to have a look at whether the winsock direct providers were installed as well. In some cases, installing the adapter just gives you IP over Infiniband...
  • Blog Post: Updated Infiniband on Server 2008 Paper

    I have finally updated my notes on the installation of Infiniband on Windows Server 2008. They now cover the released version 2.0 of Mellanox WinOF stack. You can find the document in my skydrive public folder . Let me know if you find it useful. Powered by Qumana
  • Blog Post: HPC & Movies

    In my last post I investigated how HPC can be used to build UFOs. This time, I've learned to my surprise that HPC can be used to make movies! Digital media production follows a complex workflow, from initial sketch to wireframe model, to rendered 3D images, to movies. HPC is typically used in rendering...
