[Gate-users] Gate ....

[Richard Maschmeyer]

Hi all,

This is my first time contributing to an email chain like this, so apologies if I’ve done something wrong. My Gate simulations use a lot of ram (can be >500GB or so of RAM). My solution is to run Gate in ZRAM, a feature available on Linux that lets you ‘compress’ the RAM a program uses. The compression ration tends to be very good, 20GB down to 55MB or so, https://i.imgur.com/6pRZBBO.png

Friendly regards,

Richard

Hi Pat,

Further suggestions:

  *   How many MHD files are you trying to generate?
  *   Is Gate the only RAM-heavy program running or are there others, like a heavily used web browser, or old Gate processes that were stopped but not terminated? The best way to check this is to check the memory *before* you run any Gate process.
  *   If there is no proprietary device information in your macro file: could you please post it here in the list, so that we can try to reproduce the problem?

The “time” in front of your Gate command (or any other command) is a simple utility to report the running time of the Gate process. The resources used by “time” itself are negligible.

HTH,
David

Dear Dania Consuegra,
Thanks for your response.
I had commented the visualization of my macro and had used "Gate mymacro.mac" command to execution.
But, my memory and swap system was filled up completely (16GB RAM).
Is there any differences between  "time Gate mymacro.mac" and " Gate mymacro.mac " commands?
I think If MHD file can be stored in separate files in predefined time, the problem can be solved.
I would greatly appreciate further suggestions.

Best Regards,
Pat

Hi Pat,

I had a similar problem when I increase the number of primary events. I solved it by commenting the visualization of my macro and using for running Gate instead of Gate --qt mymacro.mac, time Gate mymacro.mac ....

Good luck

Dania
