benchmarks-sync

Run benchmarks on only one concurrently executing

Intel Advisor

instance to avoid concurrency issues with regard to platform limits.

Syntax

--benchmarks-sync

--no-benchmarks-sync

Default

On (benchmarks-sync)

Actions Modified

Usage

Analyze a multi-process application running more than one process on the same host system.

Example

Run a Trip Counts & FLOP analysis for the MPI application

myApplication

. Disable benchmark synchronization to get platform limits corresponding to concurrent runs of multiple processes on the same host system.

$ mpirun –n 4 –-gtool=“advisor –-collect=tripcounts –-flop -–no-benchmarks-sync --project-dir=./advi_results:0-3” ./myApplication
