of the RECV side deeper than that of the SEND side to
avoid RNR (receiver not ready) error. The

RECV side commits sufficient recv buffers into recv queue.

during which RECV side commits sufficient recv buffers.
3) Fix server thread hanging bug.
For RDMA WRITE/READ test, No IO bytes are accumulated in server side
during test. Server thread indicates its task completion by changing

7 years agocpuio engine cpuload bug fix

cpuio engine cpuload bug fix

Current cpu ioengine always bruns out 100 percent cpu cycles
no matter what the cpuload value is. Since no data is transferred
with cpuio, bytes_done would be ZERO. Consequently, think_time
is omitted and loops keeps running.

A cpuio example is added as well.
