LHC@home

Got home this evening to find only two apps running on my HT hex core system

then finally noticed that ATLAS was using 11 of them!!

For a process that runs in Windows,I can use something like this


<app_config>
<project_max_concurrent>2</project_max_concurrent>
<app_version>
<app_name>ATLAS</app_name>
<cmdline>nthreads 2</cmdline>
<avg_ncpus>2</avg_ncpus>
<plan_class>mt</plan_class>
</app_version>
</app_config>


To limit the number of "CPUs" used

but this gives me an error of

Entry in app_config.xml for app 'ATLAS', plan class 'mt' doesn't match any app versions


Anybody have any suggestions?


Thanks in advance for any assistance

Take what you need:

<app_config>
<project_max_concurrent>6</project_max_concurrent>
 <app>
  <name>ALICE</name>
  <max_concurrent>1</max_concurrent>
  <fraction_done_exact/>

 <app>
  <name>ATLAS</name>
  <max_concurrent>2</max_concurrent>
  <fraction_done_exact/>
 </app>
 <app>
  <name>Benchmark</name>
  <max_concurrent>4</max_concurrent>
  <fraction_done_exact/>
 </app>
 <app>
  <name>CMS</name>
  <max_concurrent>4</max_concurrent>
  <fraction_done_exact/>

  <avg_ncpus>1.000000</avg_ncpus>
  <cmdline>--memory_size_mb 630</cmdline>
 </app_version>
</app_config>

I'd recommend that you set the max # of CPU's to 3, then the ATLAS tasks get about the right amount of memory reported to BOINC to allow the total memory consumption to not over load your computer too.

I have this:
<app_config>
<app>
<name>ATLAS</name>
<max_concurrent>12</max_concurrent>
</app>
<app_version>
<app_name>ATLAS</app_name>
<plan_class>vbox64_mt_mcore_atlas</plan_class>
<avg_ncpus>2.0</avg_ncpus>
<cmdline>--memory_size_mb 4900</cmdline>
</app_version>
</app_config>

<!--Set WebSettings to 3 Cores, 5GB-->

In this case max concurrent = 64GB/5GB = 12.8 rounded down = 12

Thanks,both of you

I've updated my app_config, but am now caught in the "not highest prioority" blackhole

we'll see what happens
