I do not know what happened, but all except the default GPUGRID profiles have been deleted in my account.
Trying to setup new profiles (school, work, etc.) results in an error message (that has been on this site for years: "Warning: Creating default object from empty value in /home/ps3grid/projects/PS3GRID/html/project/project_specific_prefs.inc on line 240"). Thereafter, the defined profile is NOT created (so far, it WAs created regardless of that message).
It is therefore impossible to assign computers differently to CPU and/or GPU tasks. Could someone please take a look and correct this issue?
