  You might start by reviewing IScheduler.GetJobList() (http://msdn.microsoft.com/en-us/library/microsoft.hpc.scheduler.ischeduler.getjoblist(VS.85).aspx).

  Filtering by nodegroup membership might take some work but with GetJobList() you should be able to get the information you seek.

  Since nodegroups cannot be used as a filter criteria, this must be implemented on the client side.

  Assuming "active" means "running" we get:

  using System;
  using System.Collections;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;

  
  using Microsoft.Hpc.Scheduler;
  using Microsoft.Hpc.Scheduler.Properties;   

  namespace Sample
  {
      class Program
      {
          static void Main(string[] args)
          {
              IScheduler scheduler = new Scheduler();

              scheduler.Connect("localhost");

              IFilterCollection filter = scheduler.CreateFilterCollection();
              FilterProperty filStateRunning = new FilterProperty(FilterOperator.Equal, JobPropertyIds.State, JobState.Running);

              filter.Add(filStateRunning);

              // now fetch the list of all jobs that satisfy the filter
              ISchedulerCollection jobs = scheduler.GetJobList(filter, null /* no sort order specified */);

              // build this list of jobs in desired nodegroup.
              List<ISchedulerJob> jobsInNodegroup = new List<ISchedulerJob>;

              // walk the filtered collection, look for jobs in desired nodegroup
              foreach (object obj in jobs)
              {
                  if (obj is ISchedulerJob)
                  {
                      ISchedulerJob job = obj as ISchedulerJob;

                      if (job.NodeGroups.Contains("ComputeNodes")) //<<-- put desired nodegroup here
                      {
                          jobsInNodegroup.Add(job);
                      }
                  }
              }

              // use "jobsInnodegroup" here
          }
      }
  }
