"No space left on device" error when profiling a parallel application using Intel Trace Analyzer

"No space left on device" error when profiling a parallel application using Intel Trace Analyzer

We are running Intel Trace Analyzer with Intel MPI to profile an application. It gives the following error mid-way between the execution :

.....

This problem did not occur when a smaller run of the same application was profiled, with lesser number of nodes.

What could be the reason for this problem ?

Hello,

You can set VT_LOGFILE_PREFIX environment variable pointing to a directory on a shared drive where you have huge amount of free space.
Also you can remove unneeded files from node namd2.

Regards!
