e algorithm. i.e. the problem may not lie with the inefficiency of your com=
munication between threads but just that your algorithm is not keeping the =
processor busy enough for a large number of threads. The only way that you =
will know for sure whether this is a comms issue or an algorithmic one is t=
o use a profiling tool, such as Vampir or Paraver.

With the profiling result you will be able to determine whether you need to=
 make algorithmic changes in your bulk processing and enhance comms as per =
Huiwei's notes.

I would be interested to know what your profiling shows.

Hi All,

We have a parallel program running on a cluster.  We recently found a case,=
 which decreases the CPU usage and increase the run-time when increases Nod=
es.   Below is the results table.

The particular run requires a lot of data communication between nodes.

Any thoughts about this phenomena?  Or is there any way we can improve the =
CPU usage when using higher number of nodes?
