Question Improvement of time of calculation and display 

Forum: Event and Track Management
Date: 03 Jul, 2013
From: Lafont Fabien <Lafont Fabien>

Hi all,

I would like to know if it is possible to store only some of trajectories (those I am interested in).

My problem is principally the time of calculation. During the experiment, I simulate a process which have a global efficiency of 10^-5. As a consequence, I have to (I would like to) simulate many events (more than 1/10/100 million) in order to get an exploitable result.

But this implies a huge time of calculation since there are many induced optical photons produced by alpha particles (1 alpha = 1 event) There is also a problem of memory for tracks display in dawnfile mode (60000 events)and OGL mode (10000 events).

Is there any way to reduce time of calculation and/or to solve the display/memory problem? - by considering only the energy deposit of alpha particles (I am not really interested by tracking them. - by storing only the photons tracks which come to the detector

Many Thanks in advance.

Fabien
