If you want to try a couple of patches, just for kicks, we can maybe
hack around this alleged starvation problem. First, we can toss in
a sched_yield() and see if it magically gets the kernel to make the
dbpf thread run instead. Near the bottom of the function
BMI_ib_testcontext() in src/io/bmi/bmi_ib/ib.c, there's this code:
Pete, I think you're on to something! Adding the sched_yield() call to
the BMI_ib_testcontext() function has sped things up tremendously. In
addition, pvfs2-server now only shows 10% CPU usage (and not for nearly
as long as previously) in top when doing the pvfs2-mkdir command.
I've attached the pvfs2-server.log for a pvfs2-mkdir after adding the
sync_yield call. The fact that a mkdir still takes 10% of the CPU still
bothers me, so I'm wondering if there is still some small thread
starvation problem somewhere else. What do you think?
Thanks,
