Does anyone know if it is the intent of BOINC to allow "<max_concurrent>N</max_concurrent>" in app_config.xml to override the default settings to fetch work? A project like Neurona that runs one task at a time and is 1-out-1-in doesn’t stand a chance of getting tasks especially if the other cpu tasks keep changing and their caches are always full. Moving to Numberfields@home for a short challenge seems to have upset BOINC and it cannot remember what it was doing the day before.
