Hi there,

i have my GTX Titan running for several days ... the per day RAC is dissapointing (ca. 33k WU)  :o

http://stats.free-dc.org/stats.php?page=host&proj=sah&hostid=6775938

I am using the newest beta driver of NVIDIA (314.14) and x41zc_Winx64_cuda50

and i set mbcuda.cfg settings with the following content:


[mbcuda]
processpriority = abovenormal
pfblockspersm = 16
pfperiodsperlaunch = 200



I expected a per-Day of 50-60k WU. Whats is wrong ? Is this a Kepler issue ?

Please help

Nothing is wrong, you'll have to wait weeks for your RAC to get to that level, RAC is a rolling average, it doesn't instantly increase, each Wu you do has to be done by another computer too,
so you're waiting on your wingmen to complete their Wu's, then those Wu's have to validate, give it time and your RAC will increase.

Hmm, i understand your argument but, if you have a look on the graphs at http://stats.free-dc.org/stats.php?page=hostbycpid&cpid=ee1cbaa120f830dba3ee3efb8b330470, it is not really "rocking"  :-\

One thing you need to keep an eye on is if your pending list is growing, staying around the same, or shrinking.  Ultimately for things to stabilise on a high volume card/system, you're going to need continuous running.  One the other aspect is that it's still early days for Titan. A lot isn't known yet.  Factors I *expect* to be very important with these and existing builds are that video memory clock first, and core clock second.  After that, there are special instructions for 'reductions', a major bottleneck in some portions of early & later Cuda builds.  I have no estimates on the potential impact here yet, though they might be significant in future builds.

If short, with a new architecture it can take 6-18 months to find its lifecycle peak.  Some of that transition time has been shortened by implementation of self-scaling code in later apps, though there are other technologies here yet to be explored

Currently the pending list is staying around the same, it is comparable with another system i have running with one GTX 670. That is frustating for a card which costs 985 €.  :'(
I agree with you, maybe it is to early to use this card. I will play around with Memory clock and core clock, perhaps it is possible to activate the "turbo boost" .
Thanks for helping!

There is mention of a specific OpenCL fix for TITAN in the 314.21 beta driver release notes:
