Hello All,
1. I tried to run SPDK fio with multiple nvme drives. But for some reason, I don't
see more than 1 core being used even when I increased numjobs?
Here is my config file.
=============================================================
[global]
ioengine=/spdk-master_temp_experiment/examples/nvme/fio_plugin/fio_plugin
group_reporting=1
direct=1
verify=0
time_based=1
ramp_time=0
runtime=10
[test1]
iodepth=128
rw=randread
bs=4k
#filename=0000.09.00.0/1:0000.07.00.0/1:0000.0a.00.0/1
filename=0000.09.00.0/1
numjobs=2
[test2]
iodepth=128
rw=randread
bs=4k
numjobs=1
filename=0000.08.00.0/1
================================================================
Has anyone succeeded using multiple cores?
2. I have also tried with 'perf' and I noticed that even though multiple cores
were being used but performance numbers didn't scale. Seemed like similar IOPS when I
used single core.
Any insights would really be appreciated.
Thanks,
-Raj P

As a follow up to this, I pushed some improvements to SPDK's setup scripts so that we
now more easily support vfio. That makes it a lot easier to switch back and forth between
the unvme driver and the SPDK driver. We'd happily accept more patches to improve vfio
if anyone has suggestions.
Thanks all.

Hi Robert,
We built a fio ioengine plugin for benchmarking SPDK as well as our own userspace NVMe
driver. Source and documentation are available here: https://github.com/MicronSSD/unvme
(SPDK fio plugin is ioengine/spdk_fio.c)
If you have any questions on how to use it or interpret benchmark results, feel free to
ask.

Hello all,
Has anyone done any work to make it easy to benchmark polling mode driver with something
like FIO?
Thanks,
Robert Cleveland
