Let's say you have an 8 thread CPU, and you want to download only as much work that can be crunched at a time. Simple enough, change the project resource share to zero, and only 8 single-threaded tasks will download. But now let's say I am using an app_config.xml file to force tasks to multi-thread and use all 8 threads, like you can do on primegrid. Even with a resource share of zero, it will download 8 tasks. Then one will crunch using all 8 threads, and 7 will sit there waiting their turn to run. Is there a way to force BOINC to download only 1 task at a time, in this situation? I though there was a option in the cc_config.xml file that would enforce a maximum number of tasks per project, but I can't find it. Maybe I am remembering it wrong. Any ideas?
