Without examining the problems and the output from both versions of
the code, it's difficult to say exactly what could be the cause of
this improvement in performance.
There were relatively few changes to the code between version 5 and
version 6 of CSDP, and on a single processor machine the OpenMP stuff
should make no difference in performance. If you see that both
versions 5 and 6 used about the same number of iterations then I'd bet
that any improvement is due to using a more highly optimized set of
BLAS/LAPACK libraries when the newer version of CSDP was built.
