Mixed installation? RRS feed

  • Question

  • Is it OK to use a mix of different machines when building a cluster?  (Such as, some machines using Intel CPUs while others using AMD.)  While it could sometimes be confusing with some nodes running faster than others, it might be nice to have some options for testing different configurations.

  • It's definitley OK to do this; in fact we've included a number of features in v2 to help you target jobs to specific types of nodes should you need to schedule based on these hardware differences.

     

    As you say though, it can cause some performance problems (especially with MPI jobs).
