    Is there any programmatic way to determine the name of the head node?  I'll take answers in C# or F#, or if you could point me to the correct api I could probably work it out on my own.

     

    Thanks in advance,

    Bob

    What do you mean by name of headnode? Also, where is your code running? There could be multiple head node in a network, so to know the name of the headnode, you must specifiy a headnode...

    In case your code is running on the compute nodes which belong to the cluster, you can get head node by environment variable %ccp_scheduler%

    Would this work on a Workstation node as well?

    I'm assuming a cluster with only a single head node, and the code might be running on a workstation node, a compute node, or even the head node itself.  Thank you for asking good questions which allow me to explain my scenario more clearly.

    The environment variable %ccp_scheduler% is available on all the nodes in the cluster, including headnode, broker node, compute node and workstation node.
