Hi,
Could you tell us what scenario you want to accomplish so that we can provide more accurate information?
And here are some simple answers to your questions:
1. Scheduler Service running on the headnode will query the DB, getting information about Node Resource and Job Queue. And according to scheduler policy, node resource will be assigned to queued job, after a job get node resource, the job will go to running
state. And then the tasks in the job will be dispatched to the compute node (With Job and Task information). And then the task will get executed on the compute node
2. Job/Task information are passed to the NodeManager service running on compute node from scheduler service. And then the result will return back to the scheduler from the nodeManager when the task finishes. in HPC Pack 2012 R2, the communcaition between
headnode and windows computenode is through .net remoting channel while the communication between headnode and linux computenode is through REST call
