Maybe that particular machine does not meet the requirements: 1,024 MB available memory and 2,048 MB disk space.

(1)

Project Specific Settings
Number of workunits per host for
The Clean Energy Project - Phase 2? Unlimited

(2) The machine has 3957MB of RAM and 98.8% free on a 250GB HDD (and pulled CEP2 work units when it was running windows [currently Arch Linux])

Lawrence,

The machine has (in addition to the 3957MB of RAM), 5969MB of swap (though admittedly I've ran 4 concurrent CEP2 work units on a machine with the same distribution of Arch Linux where there was 0.0KB of swap [and 12GB of RAM], so I'm not sure I see how this is relevant).

Additionally, the cc_config.xml file is as follows:

<cc_config>
   <log_flags>
   </log_flags>
   <options>
      <ncpus>2</ncpus>
   </options>
</cc_config>

(This is because I also run F@H on the machine, and it needs to reserve 2 of its 4 cores for feeding my 2 GPUs data)

Additionally, the www.worldcommunitygrid.org folder's app_config.xml file is as follows:

<app_config>
   <app>
      <name>cep2</name>
      <max_concurrent>1</max_concurrent>
   </app>
</app_config>

Additionally, my computer only connects to the internet for 2 hours per day (while I am sleeping, and thus not Netflixing).
The above configuration should allow for the download of multiple CEP2 WUs per day, while only allowing the machine to work on a single CEP2 WU at a time (it is rather limited in RAM, after all).

Yaren,

Neither

lib32-glibc

nor

lib32-glib2

were installed as of when you asked your question. I since have installed those packages and am hoping for WCG to be able to request the CEP2 package without a client restart.

If it hasn't successfully downloaded the app by morning, I'll restart the boinc client.
