" * client: undo [17160]. <ncpus>0</ncpus> in cc_config.xml  no longer
means simulate zero CPUs. There are several places that divide by
ncpus. Zero CPUs doesn't make any sense anyway. "

Then how do you set BOINC to not use the CPU, but only the GPU(s)?
How do you set that for one computer only? An option to only use the
GPU is not available in the local preferences. Setting "On
multiprocessors, use at most 0% of the processors" won't stick. It
resets to 100%.

That's why <ncpus>0</ncpus> was created, to be able to let BOINC use
the GPU(s) only There are persons out there who have multiple GPUs in
their system and only use those on the projects that give GPU apps
out; they do not use their CPUs, or at least, not for BOINC.

I know my workaround was dirty, but please, do consider adding a new
flag for the next BOINC, like <nrcpus>; that one will ignore the old
<ncpus> setting, but won't break its use on older BOINC versions.
