Can Vtune be used in a computer cluster environment?

Hi, There,

I have a professor from one university asking the following question:

"Getting VTune installed and running on the cluster will apparently require significant modifications including installing drivers on all nodes. We are trying to weigh cost/benefit of installing these tools and were hoping that you or someone you could point us to could help us find the easiest and least invasive way to install them"

Could any Vtune expert in this forum give some info if Vtune can be used in a computer cluster environment?

Hi Tao:

There is no special support for clusters in the VTune analyzer. Generally, we recommend installing it on one node and profiling the activity there. That is, if it is an MPI app, the data is split up per node, so the work is similar on each node. I would never recommend installing the collector on every node. There is no way for the analyzer to collect data from each node and correlate it.
