Follow up for #2415: we should be able to select the list of enabled / disabled devices using their name and / or PCI bus location (ie:
0000:1A:00.0) without doing a full CUDA context initialization.
load_device can get to the device name before calling
make_context (which is slow).
We can't skip the
make_context completely in
driver.mem_get_info() requires a valid context.
Maybe we can have different policies for load balancing, and one may not require memory info to do its job.
r24340 adds a
load-balancing attribute and a
round-robin option, the
memory policy is still the default. (chooses the GPU with the most free memory)
Still needs testing.
Seems to have caused a bug: #2489.
See also initial load balancing code in #520.
See examples in browser/xpra/trunk/src/etc/xpra/cuda.conf.
