Re #55:
It's late in the day here, and I don't have AMD GPUs myself... This coproc_info.xml looks good and it is unusual why tasks are put onto your GPU 1 but not onto your GPU 0. Can anybody else make something of it?
Re #56:
Some boinc-client installations start out without cc_config.xml, since it is optional. Other installations come with a cc_config.xml which is populated with
all possible options, all set to their default values.
You can create a minimal one:
XML:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>
When you create it (in the boinc data directory), make sure it is a text file but with the exact name and suffix, and that the boinc pseudo user is permitted to read it. After that, restart the client.
