Re: [Condor-users] Condor Benchmarking on Windows Platform

[Dan Bradley <dan@xxxxxxxxxxxx>]

Hi James,

The Condor source code for version 7.0 and beyond is fully available on 
the downloads page.  The benchmarking code hasn't changed since 6.8.6.

For calculating MIPS, Condor calls sysapi_mps(), which uses the 
dhrystone benchmark 2.1.

For calculating KFLOPS, Condor calls sysapi_kflops(), which uses 
Linpack.  From a quick glance at the code, I can't tell which version it 
is.  In the Condor source, it's in the file src/condor_sysapi/clinpack.c.
