GAMS CPU time

GAMS
1

Dear all,

I know in gams the elapsed time can be retrive by the couple of instructions:

scalar starttime; starttime = jnow;
…
scalar elapsed; elapsed = (jnow - starttime)243600; display elapsed;

but how can i retrive the cpu time spent in gams by my code?

Thanks in advance,
Luca

Hi Luca

There is an option “profile” to have a closer look at the time used by Gams. You can find more information Profile option and here McCarl.

Hope this helps

Luca,

CPU time make little sense in today’s multi-threading world, so reporting CPU time has gone out of fashion.

usually I test code with single thread and I report this CPU time.
otherwise what you suggest to do ?

Thanks,

Take an empty/idle machine and give it all the juice/cores it got (I would not do hyperthreading) and report wall time.
