Shouldn't the server be loaded with much more TRP LLR work?
As of this moment I can see 187/600 WUs, not that much for a challenge?

AMD Catalyst: 13.4
Genefer OpenCL version 3.1.2-2
CPU load: <1%
GPU load: 97-99%
Runtimes: 26,516 - 28,080 sec

Edit:
So 3.1.2-4 is definitely faster

My first WU with Genefer OpenCL on my 7950 is complete and validated:

It took 27,721 sec.

For reference, it seems that OpenCL version is faster than CUDA on GTX Titan.

CUDA:
538452^1048576+1 Time: 1.75 ms/mul. Err: 0.2031 6009544 digits

OpenCL:
538452^1048576+1 Time: 859 us/mul. Err: 0.2266 6009544 digits

Wow, OpenCL is almost twice as fast on your Titan! That is totally unexpected.

Testing on a HD7950 with 1 CPU core reserved, estimated time for a WU ~28,000 sec.

Are you sure these figures are correct?

That fits to about the average run time per unit, so on the 7th-9th a bunch were sent back into the wild and they finished. I bet the numbers are just fine.

I meant the 980 results returned for the team positions, while only 392 results have been returned in total?

From 13 to 14th of May: -392 tasks outstanding; -301 tasks in individual; -980 tasks in team??
9) Message boards : Number crunching : New badge proposal - discuss! (Message 64920)
Posted 2304 days ago by Profile VictordeHollanderProject donor
I like the first 'new' badge system with multiples of 10x and the distinctive colours. I see no reason to add 10+ badges, as only a handful of people will accomplish them, but who am I with only 4 ruby badges.

edit:
Just keep it simple like this:
10M
100M
1.000M = 1B
10.000M =10B
100.000M = 100B

Although I'm not really fond of royalty, it's always nice to have a day off and party.
So, happy Queens night/day from the Netherlands!
