From: Yufei Ren <renyufei83@xxxxxxxxx>
Three patches and a numa integration is present as follows.
Yufei Ren (4):
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.
If `thread' option is enabled, resource usage should be thread
based instead of process based. For the following job,
rdma ioengine improvement
Two new options, numa_cpu_nodes and numa_mem_policy, are created
for a fine-grained job level numa control. Please refer HOWTO and
README for detailed description. A example job,
examples/numa, is added as well.
