hs

bool rearr_comm_fc_opt::hs

Enable handshake.

Enable isends - if false use blocking sends.

Max pending requests (PIO_REARR_COMM_UNLIMITED_PEND_REQ => unlimited pend req).

This is the number of messages allowed to be in flight at one time. On some systems posting all messages at once creates a significant bottleneck in communications and throttling in this manner improves overall performance.
