Dear all,
after some testing (thx Ken) I just released a new Pfind
https://github.com/VI4IO/pfind

That one strips the libcircle dependency and adds some more features
for debugability.
Hopefully, that simplifies using IO-500 even further.
It has been tested with OpenMPI, MPICH and IntelMPI.

During testing it was a bit faster than the past version *and there is
now room for further improvement*.

Note that there IMHO is a way of gaming the value for find the way we
have setup IO-500, and I will give kudos to someone that actually
exploits it :-)
It is not trivial, though. The usage of the flags -C -P might be helpful.
You can test it without using IO-500 of course as well.

I e.g. run it with:
mpiexec -np 10  ./pfind /home/test/ -C -P -D rates

Best,
Julian
