Regarding proper using multicores

Asked by shibasipu on 2017-08-09

Hi Olivier,
                    I am using Madgraph in a machine with 24 cores. During job running, it is showing "Running 24". But while completion,
one is completed at a time. I am just pasting a part of the screen output.

=======================================================
is it ok ? I have not changed anything in the mg5_configuration.txt file. Since job idle is completed one by one , it is taking a long
time for entire job completion.

Hi,

Actually this is not true. You can see that sometimes you have two completed in a single line:
> INFO: Idle: 71, Running: 24, Completed: 462 [ 15h 42m ]
> INFO: Idle: 69, Running: 24, Completed: 464 [ 15h 43m ]

The point is that such line is printed as soon as a single job finishes but to avoid that such line is printed too often,
We forbid the line to be printed twice in less than 30s.
The fact that the line is updated by small/large number has nothing to do with the number of instance of the code running on your machine.

Cheers,

Olivier
