- Subject: OpenMP and its testing
Frankly, I think that this is asking for trouble. We are a parallel
shop, and my experience is that most C OpenMP implementations are
very sick - my experience is that only half of the major vendors'
implementations work at all. The reasons should be well-known, but
please ask me if anyone wants to know more.
Anyway, I have some crude tests that I wrote because I couldn't find
any on the net. These are based on versions of C and Fortran Linpack
and Schwarztrauber's FFT that I got off some site (perhaps netlib).
I am happy to allow free use of any parts that are my copyright,
but the majority is of course the original authors'. And there don't
seem to be any copyright notices attached, but I am prepared to state
that I have not removed any and that my understanding was that they
were usable without conditions.
If you are interested, I think that it would be fairly easy to check
up on that.
Anyway, even if not, I am very happy to collaborate on the testing (and
perhaps even development) of OpenMP application-style tests and timers.
I can test them on a range of other vendors' OpenMP compilers. I am
NOT a CVS user and hope to remain that way!
