Likelihood computation performance reduced with BEAGLE 3 on CPU #1037

Running BEAGLE 3 on CPUs with Multi-Partition extensions degrades performance significantly.

rambaut commented 6 years ago

When not using GPU, it is better to create multiple BEAGLE instances within threads that to use the multipartition extension with internal BEAGLE threading. Now automatically chooses to use multipartition extension only if on GPU/OpenCL and >1 partition. Can be overridden with a command line option.
