Historically, the OFI BTL has defaulted to only supporting one-sided operations (ie, the RDMA OSC component). Howard and I can't think of a current Libfabric provider that has a performance difference when in one-sided vs. both one and two-sided mode, so change the default to support both. This allows users who want to use the OB1 PML to specify `-mca pml ob1` without also having to change the default mode in the BTL. Signed-off-by: Brian Barrett <[email protected]>
