This is part shameless self promotion, but also meant to stir some discussion..
Take a look at some of the recent top results for SPEC ACCEL
/* It may not seem like much, but I can say that is the visible result
to a heck of a lot of work */
I have to word this carefully, but after that was submitted we fixed a
cooling issue and the score went higher.. expect better public results
in 2 weeks. (Anyone want to party at GTC?)
Frankly, it's visible we still aren't the best performance on some
codes.. Those issues basically fall into two camps and we're working
Having said this..
Would anyone build an AMD GPU cluster if
1) The GPU was 30-40% faster than a K40
2) It cost less
3) OpenACC/OpenMP4/CUDA programming models were high performance and supported
4) More oncard ram
The s9150 is a top end card and priced relatively in the same ballpark
as the competition..
Forgive me for sounding like a salesperson.
If you don't need all the ram on the card - there's the w8100 (with
fan on the card) - $1050 on Newegg! (Why do I feel like an
I have 2x w8100 in a server for benchmarking and they are nice GPU.
Not as fast as a K40, but beats other cards.
