BOINC insists on running two GPU tasks on my single GPU, even though I don't have an app_config.xml or an app_info.xml. The only thing I have in my cc_config is use_all_gpus set to yes. I looked at coproc_info.xml, and it lists my GPU twice for some reason. Thinking that might be the problem, I removed the file, quit BOINC, reinstalled BOINC just for good measure, restarted BOINC. It recreated the file with two listings for my GPU and is still crunching two tasks on it concurrently. Any ideas?
