That is what I though looking at the documentation but wanted to be sure.  

Thanks

Unfortunately N to 1 is mostly a lock test. Sfs2013 is benchmarking the performance of the shared file system but not shared access to same file. Each client access separate files. For example when we test Lustre we use the option -o flock to be able to run the benchmark.
I hope this is what you asked. If I mis-understood please feel free to ask more clarification questions. (N-1 for me means multiple processes writing in parallel to same file). Thanks for your patience

Does sfs2013 support N to 1 I/O?

Per the discussion during the call, attached please find the documentation of sfs2013 benchmark (currently called netmist).

Please take a look and let me know if it is of interest to continue on this path of action for the Lustre benchmark. I will be attending the LUG and plan to introduce sfs2013 benchmark. Thank you for your understanding and patience

When:   Friday, March 23, 2012 11:30 AM-12:30 PM (GMT-05:00) Eastern Time (US & Canada).
Where:  1(866)844-9418 id 4088226016

The OpenSFS Benchmarking Workgroup aims to provide an I/O benchmark suite to satisfy the benchmarking requirements of the scalable parallel file system users and facilities. Towards this end, as a first step, the workgroup aims to characterize the I/O workloads from small- to very large-scale scalable parallel file systems deployed at various high-performance computing and parallel computing facilities and institutions. Using these gathered characteristics, the workgroup will then collect and build the required I/O benchmarks to emulate these workloads and provide required documentation about the benchmark suite.

The workgroup meeting will reoccur every Friday at 8:30am Pacific time. 1 hour each. The dial-in is as follows: 1(866)844-9418 id# 4088226016.

Also note: we will be having our first face to face meeting on Sunday April 22nd from 2:00-5:00pm at the LUG.  Details to come.

On Tuesday April 24 4:10-5:00pm there will be a Benchmark panel discussion moderated by Sarp Oral. Panelist will be Jeremy Filizetti (DOD), Andrew Uselton (NERSC), Eric Barton (Whamcloud), Nathan Rutman (Xyratex), Stephane Thiell (CEA), and Stephen Simms (IU).

If you are interested in contributing to this work group, please email Sarp Oral at oralhs at ornl.gov<mailto:oralhs at ornl.gov> or myself at richard.vanderbilt at netapp.com<mailto:richard.vanderbilt at netapp.com>.
