      <description><![CDATA[ The natural question is if VTamplXE can help with analyzing performance of MPI applications with tasks running on separate nodes as in:

1) use the command line VTampl to launch the MPI code across nodes, such as,

  mpirun -np 4 amplxe-cl -collect hotspots -result-dir "./$(hostname)" ./myMPI ag1 arg2  ....

 which will save collected data in a separate directory according to the node the command ran.

2) Can now VTampl  "combine" performance data collected on these separate directories and consider them as a single application ? 

As a matter of fact the above could work on any distributed application (processes talking to each other by message passing on sockets, etc.)

Any suggestions ??

thanks
Michael
