Supercluster interactive single-CPU
We strongly recommend that you try your code first on a single CPU with a minimum number of processes. For instance, if your decomposition is n-way scalable, then perform your initial debugging with n = 1. This will flush out many problems without the added complication of parallelism. At this stage, small test cases are appropriate so that running time is kept short to allow for interactive debugging. The Supercluster implementation of pGenesis also supports Xodus displays, which can also be useful in ensuring that your scripts are functioning correctly.
For more information on the Supercluster, see the PSC Supercluster web page. We present here only the essentials for running pgenesis.To try an example script:
In our single slice case, there are actually 3 nodes, since 1 is used for control and 1 for display in addition to the 1 handling the single slice. Here we are running all 3 of these node processes on a single CPU, e.g., axpfea. See the web page on orient2 for additional details.
