  • Authentication Failure error on Windows HPC caused by port conflict

    I recently ran into an issue where all attempts to run any cluster command from the command line resulted in an authentication failure. We were able to connect to the cluster from the GUI and powershell however all attempts to connect to the cluster from...
  • How to Capture a “Master” Compute Node Image Using Node Templates

    Whenever I discuss image management capabilities of the HPC Cluster Manager, one question which invariably arises is, “How do I capture an image of a compute node which has been customized so that I can use it as the ‘master’ for deploying to the rest...
  • Accessing an NFS Server from Windows HPC compute nodes

    Because most HPC environments already have enterprise data stored on an NFS server, we often get asked how to enable the Windows HPC compute nodes to access the NFS server. In Windows Server 2008, the NFS Client is included as part of the Services for...
  • DNS Suffix vs. Active Directory Domain for HPC cluster (Part 2)

    In an earlier post , I described an approach for resolving names when the connection specific DNS suffix did not match the Active Directory domain name. Recently, I realized that there is a much simpler solution. The Default ComputeNode Template which...
  • Windows HPC WCF/SOA tracing

    I was recently looking into a failure in a WCF client application that runs just fine with the debugger attached but fails to run stand alone. The error message was as follows: Microsoft.Hpc.ServiceBroker Warning: 0 : Service net.tcp://private.TestHeadNode...
  • How to set environment variables on computes nodes

    For ISV application you have to set some environments variables on the compute node. You can set this variable by hand, but if you have many nodes it can be long. So, the idea of this post is how can set them attaumaticaly ? Use the HPCS tools : ...
  • Troubleshooting Windows HPC WCF/SOA Issues

    HPC uses HPC sessions to support the service-oriented architecture (SOA) programming model based on Windows Communication Foundation (WCF). Sometimes troubleshooting errors from this SOA based applications could be challenging. However this tip I'm about...
  • Helpful tip for dealing with HPC Pack setup failures

    I once ran into an issue while installing the HPC Pack on a machine and I was wondering where to go to find more information about the setup failure preferably a log of some sort to see the reason for the failure. Here is a tip that helped. The HPC...
