It's taking 20+ hours on a single cpu core to run a single non MT workunit, can I use an app_config.xml file to run one task using multiple cpu cores. Something like this:

<app_config>

<app>
<name>camb-legacy</name>
<fraction_done_exact/>
<max_concurrent>1</max_concurrent>
</app>

<app_version>
<app_name>camb-legacy</app_name>
<cmdline>-t 4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>

<app>
<name>planck</name>
<fraction_done_exact/>
<max_concurrent>1</max_concurrent>
</app>

</app_config>

The problem is they only have 2 kinds of workunits right now that being one of them. So if I could use multiple cpu cores to run them they would run much faster.

On top of that every single one of the camb_boinc2docker workunits errors out within about 20 seconds of starting them.

That app_config.xml file I wrote is wrong as it doesn't work.

Do you have any projects successfully working with Virtual Box? You can look at Yeti's check list at the LHC at home forums. Do you have a specific computer giving you trouble? Check to make sure virtualization is enabled and check the FAQ on cosmology. Your hostid=397049 says disabled.

I have several pc's doing other Projects at the moment but I have a few I need to move to someplace else soon and when I tried to do the camb-boinc2docker units on one of them every single one of them errored out very quickly. The normal units run just fine, they just take forever, and VBox is installed with Boinc. I have 5 dual quad core Xeon cpu's that should do okay here but since their speed is as slow as a laptop they take a long time to run the non MT units. I have several pc's running the camb-boinc2docker units just fine but would like to have the 16 core pc's, thru HT, running them as well to just bang them out.

Camb_legacy has no real scientific value apparently.
However, if you are still interested in crunching it change project preferences to use more than one core and max 1 job, uncheck other projects and see if this works.

And "plank" project is finished

I tried this with my magical 8 core and there was not enough significant difference that I could detect, on the contrary each job accepted the 1.5 cpu. it appear that the usage went up maybe a decimal point. good luck and cheers

<app_config>
<app>
<name>camb</name>
<fraction_done_exact/>
<max_concurrent>5</max_concurrent>
<app_version>
<app_name>camb</app_name>
<cmdline>-t 8</cmdline>
<avg_ncpus>1.5</avg_ncpus>
</app_version>
</app>
</app_config>

planck is still on the menu. when I run camb the first job from the download batch(of 25) usually takes 7 hours then the rest take between 10 and 17. I dunno if interruptions are the main cause.
