Basically, I want to conduct some tests with WCG and a few PCs I have, and I need a controlled ambient for that.
----------------------------------------So the question is, can I "force"a set number of applications to run at any given time? I have a 16 thread machine, so could I force the client to always run, say, 5 instances of OET and 11 of CEP2? I'm asking this, because on my 3 threaded machine I have at home, there are moments where it's running 3 applications from OET and 0 from CEP2.  Want to have an image of yourself like this on?

Put this in a file called app_config.xml: <app_config> <app> <name>cep2</name> <max_concurrent>11</max_concurrent> </app> <app> <name>oet1</name> <max_concurrent>5</max_concurrent> </app> </app_config> Put the file in this folder: C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org For more info see http://boinc.berkeley.edu/wiki/Cc_config.xml and/or search this forum for app_config.

I am not sure if App config will work for oet. It is low priority and AFAIK it will be downloaded only if it is selected as an exclusive project in profile

imakuni, long as you restrict CEP2 to 16 or less 'In Progress' on the host in the device profile, you will get all you need for OET1, in that profile combo. Soon as you add any other sciences, you won't get enough of OET to even keep 1 core busy. Expand the app_config to add e.g. UGM1 to for instance specify 5. What happens then is there's an overlap [11+5+5] where in incidences you could have a little less CEP2 running and several UGM+OET.
----------------------------------------Summary, app_config works best with only 2 sciences and you have to consider the supply weight, where CEP2 is -always- send first [if there's work, which is 99% of the times]. Having overlaps, sum of apps max_concurrent is greater than core count, prevents idle cores if only computing at WCG. [Edit 1 times, last edit by Former Member at Mar 13, 2015 9:15:25 AM] |

It is low priority and AFAIK it will be downloaded only if it is selected as an exclusive project in profile you select 2 project run in My profile...only those are sent (unless you also affirm the "send other science if work is not available")! and you put that app_config...and it will work! :D |

Ty everyone for the replies. I'll try it once I get home.

Well, it seems that this solution was perfect. Although it was only a 3 threaded machine, I was able to completely control the number of WUs from each project, in whatever way I wanted. Tyvm for the quick response.

As good as it is, it can't overcome some project-specific issues. Since I am not familiar with OET1 WCG sub-project, I was sceptic about its usefulness with it  Crunching@Home since January 13 2000.

Hi I have kind of the opposite question. FYI I know almost nothing about programing.
----------------------------------------What if I dont care about the max concurrent number of WU's? What if all i care about is having at least one instance of a project running at all times? all this w/o affecting the all other parameters. In other words not running dry on the other sciences. Can I do this with app_config as well? Thanks  Barranquilla procera e inmortal. Corroncho Crunching |

You don't need app_config at all... set the My Projects to sent all [Tick all sciences except CEP2]. When selection is set this way, you don't even need the 'If there is no work...' as then the servers already assign anything available in the hopper... kind of the preferred way of operation by WCG. :D
