Timer for PLASMA

Postby jgpallero » Fri Jan 04, 2013 7:54 am


Can I use safety functions as gettimeofday() (POSIX) in order to conpute the execution time of PLASMA functions? I ask about because for example in OpenMP the omp_get_wtime() should be used in order to manage the possible various threads that can mislead other standard time functions.

You can use safely gettimeofday() to time PLASMA functions.
If you are using the standard (LAPACK) interface, simply put the calls before and after.
If you are using the async interface, remember to put wait after the call (and before the second gettimeofday).
