The "Oh My, Look Who Has Pie" Thread

[jeanguy2]

I am not in the club yet. But a few minutes ago my two new black holes two ASUS HD 7970 Direct CU II went into orbit. This should definitively allow the hyperspace jump over 1M Boinc points/day.
Thanks for the thread. Impressive machines. At the moment I have still one GPU board per CPU. I hesitate to do multiGPU yet. The fact that the CPU has to split itself among the two GPUs, I wonder if it does bring down the performances of the whole set.

Eta,

Sam was originally using 3 X 7970 cards on that rig with a 3930 CPU with 8 X ATI GPU WUs threads per card. One video card packed it in and he switched the two remaining card to a a new unknown config (likely 12 X ATI GPU WUs per card). Whatever he ended up settings gave him a PPD production that almost equaled that of the previous 3 video card setup. With a 3930 CPU and 2 HD 7970s doubling the CPU to 24 and running 12 ATI GPU WUs per card may just be that rig sweet spot. Each cpu likely as its own sweet spot depending on the two video card you team them with. likely applies to singleton video card setup as well. The rig that has your 3960 cpu in it might just be the one to experiment with.

Can't wait to see what them new ASUS HD 7970 Direct CU II will do for you.

Let me know what Pluto looks like when you warp by...!!!

Sam, I see that you are not laying back and letting a young Swiss lion's challenge go without a fighting response. Looks like you might be headed for a 2 million PPD BOINC points goal.

Eta, I forecast avalanches and melting snow caps in your vicinity.

Excellent work for both of you....

jeanguy2, unfortunately Pluto was a kind of very fuzzy oval distorted shape, and Charon was unvisible. Probably this is due to me passing Warp 1 speed too near Pluto. Now heading towards Proxima

I understand what your saying. Warp 1 Earth to Pluto 5H 28 mins. You were definitely moving. If proceeding to Proxima in the Alfa Centauri system suggest you increase speed to at least Warp 8 (1024 X c) for an estimated travel time of roughly 73.5 Hours. Warp 8 travel Earth to Pluto would have taken you 19 mins.

There must be like 50 days GPU processing left or 1'200 hours at present consumption rate.
Proxima is 6'724 time farther than Pluto. This means that at present speed I would need 36'757 hours to reach it before I run out of fuel. So I must increase my speed by 30 times. Now if I really do that and crunch 210 Million WCG points a day then the problem is that I would dry up the whole available fuel in less than two days. !
Proxima is too far. I change plan, lets go and visit the fabulous liquid Hydrogen fountains of Eris just twice the distance from Pluto. I will have time to wander in the Kuiper belt, around see the beautiful ice sculpted canyons of Haumea, and the fantastic caves with liquid helium lakes of Makemake

Eta,

Sure glad to see you are going to keep your speed down and leave a few HCC GPU WUs for the rest of the XS WCG team to crunch.

Happy trails.... Keep a long range sensor on for them unplotted asteroid fields.

Later on today I shall use NASA's long range scanners to view your wonderful destinations.

I always learn something new everytime Eta posts

I will leave my slice of the pie, for a few days. I am sure some of you will be happy to taste it. I am flying now with the blue angels, and then will be back.

[totalgeek]

I'm still kinda shocked that I'm actually getting a piece of pie. Might be short lived, but it sure is tasty.

Do not swallow this delicious slice of pie too quickly. Take your time. It will taste longer.

[EtaCarinae]

Sam you are approaching Warp 2 speed. Be careful, the faster you go the more difficult it is to slow down.

[jeanguy2]

I will leave my slice of the pie, for a few days. I am sure some of you will be happy to taste it. I am flying now with the blue angels, and then will be back.

If you are going to fly with the Blue Angels, try to get in with either the slot man or one of the solos. This will give you a better view of the formation work as well as a better situation awareness. Flying with one of the two solos would be best because you will get to see the formation work as well as their low level aerobatics. Flying inverted, 200 feet above the deck doing 500+ knots will get your hair on fire.

Wishing you a great rides. Whom ever you fly with remember to tell him when he asks what you would like to do: "I was born to turn and burn". Then hang on for the ride....!!!

I am estimating that it takes 3 GPUs to get into pie, am I right?


Good job all the way around!

Two OC 7970's on separate machines should do

Sam,

I just about to put in an MSI R7970 OC 1010Mhz on the system below to teplace the 6990. I have BOINC v7.0.36 and plan for AMD CAT 12.11 beta 4. What do you recommend for software & driver versions as well as the optimum number of ATI GPU threads to run...?

Thanks,
Jean-Guy

I systematically load in addition to the latest AMD beta drivers the latest AMD APP SDK, and run 10threads.

[stoneageman]

I'd run 16 threads with your software & driver & crank that clock up to 1125

Thanks for the inputs Eta & Sam. I will work my way up to 16 threads and an 1125 OC. I will use the AMD 5.11 beta 11, the AMD APP SDK and MSI Afterburner 2.25.

Eta, How was your flight(s) with the Blue Angels? Sure hope that you did not have to use the little white bag....

I forgot that about the clocks. My clocks are also up some to 1150. It depends on the manufacturers. You can go over but then I have long term stability issues wirrh freezing. Some GHZ editions are very good other pretty bad. Jeanguy2 you have to carry some tests on your particular board.

I have not tried more than 12 GPU threads or 1 CPU per 1 GPU. It means you must split the CPU with a ratio of 0.75 instead of 1.0.
With 12 GPU threads it did not give me the feeling that it was making a big difference over 10 GPU threads.
I will check this.
