I think we should start EnergyPlus Benchmark Test, something similar to what Mark Stock has done with Radiance:

I think you need to repackage the 16 Ref Buildings, make a group run or something, and let people report back.

I recently purchased a solid state drive in hopes that it
would increase the speed of EnergyPlus 8.1 simulations. I
ran some benchmarks of the simulation files on either the
solid state drive or a disk drive and the EnergyPlus program
on the solid state drive or disk drive. These were run from
EP-Launch as a group and the temporary files were located
where the input files are. I set EP-Launch to use one
simulation process at a time. The operating system was on
the disk drive. I took the elapsed time from the ERR file
and also reported the timestamp of the first and last file
to be created by the group of simulations. See the first
four columns of results in the attached spreadsheet.
The conclusion surprised me: the solid state drive made
almost no difference.
While I was at it, I ran the same simulations on some other
computers I have.
To do the benchmarking, I just used the 16 reference
buildings that come with EnergyPlus 8.1 but made them all
annual simulations, also attached.
Feel free to add your own test results to the spreadsheet
and redistribute but please describe the computer
configuration. Can anyone's computer beat 1415 seconds?
