KEEP-RAW-EVENTS

Syntax
KEEP-RAW-EVENTS [on|off]
Variable
VT_KEEP_RAW_EVENTS
Default
off
in Intel Trace Collector
Description
The Intel Trace Collector can merge the final trace from the collected data at the MPI finalization stage. Sometimes it may take much time, especially for large amount of MPI processes and for applications rich of MPI events. This option forces the Intel Trace Collector to store the raw data obtained in each process into the disk without the merge. Then, you can use the merge function offline.
