When runing a Atlas task, BONIC always displays waiting for memory

If you unhide your computers it will be much easier to look through your result logs and diagnose the problem.

Running ATLAS on a host whith lots of cores (here: 12) but only 8 GB RAM might not be a good idea to start with.
The VM started by each task will allocate 6600 MB RAM by default (4-core setup) and the log shows that the BOINC client paused and restarted the task several times:
Those restarts are extremely inefficient and very often they end with unsuccessful tasks.
It may be better to deselect ATLAS and focus on SixTrack and Theory on this host.
Theory may be limited to a 2-core setup using the following app_config.xml:
<app_config> <app_version> <app_name>Theory</app_name> <plan_class>vbox64_mt_mcore</plan_class> <avg_ncpus>2.0</avg_ncpus> <cmdline>--memory_size_mb 830</cmdline> </app_version> </app_config>
"Read config files" from the menue must be run or the BOINC client has to be restarted or to activate the changes.
Already running tasks will not use the changes.
The format of an app_config.xml is specified here:
Other parameters than specified will be ignored by the BOINC client, hence it makes no sense to specify <max_ncpus> like in GreenHat's post.
The nthreads setting there is also redundant as the BOINC client will correctly configure the #cores for the VM according to <avg_ncpus>.
Especially for inexperienced volunteers it's hard to follow your advice without having a chance to check them against your logfiles.
In addition mcplots does only show computers that are attached to Theory.
Computers that only run ATLAS or SixTrack are not shown there.
Hence it is highly recommended that you make your hosts visible.
It would also be nice if you could mark an URL as URL.
