Default Ubuntu saddies

Hi there.

I just received a message saying that my Ubuntu version 11.10 was supported no more.

As I am a CUDA addicted, before starting the update to 12.04 LTS I would like to ask for instructions:

1 - My previous uodate from 10.10 ran smoothly, and even the drivers updated to the newest available.
2 - I guess I should update the SDK and the CUDA runtime as well?
3 - I remember that some CUDA program had problems with CUDA 5.0 - Has the glitch been correctd since then?

Im working on cudalucas code with Cuda 5.0 64 bit AMD cpu with Nvidia Titan cards on Windows.

At this moment I am adding Hyperq. Too bad you are running Linux, otherwise you could benefit from my compiles on windows.

My compiles are running very stable. VS 2010 and Cuda 5.0 with V100. so its all the latest and greatest.

That's relieving, thank you!

I actually have one GTX 580 and one GTX 275, the latter used for double-checks.

Ok, did you see my speed increase with GTX titan with cudalucas in the cudalucas thread ? interesting read. what Im doing with HyperQ now is worth purchasing the GTX titan..

But you need windows for GTX titan, as you need to downclock memory 500 mhz.. as the mem chip on the backside of the card gets burning hot and produces errors.
On linux I heard you cannot downclock the nvidia cards.

I'm involved in different math searches, and don't feel pressed to buy the newest hardware just to increase my productivity...

You did a great work with HyperQ, but I'm actually satisfied with my GPUs (I will buy a new Ivy Bridge when my motherboard gets fried again, tho).

Downclocking a Titan would be like buying a Mustang Boss 8V and install a 6i engine on it because otherwise you burn your tires when you start going. It would be impossible to sell, except for the IT market...

Well, its a question about what is being downclocked actually.
I only downclocked the memory, the Titan board itself adjusts the clock whenever it needs to to keep itself within the heat profile.

I measured the speed drop, and it was very little 6-8%. Now with HyperQ speed increase on the existing code.. thats a good reason to buy Titan for compute reasons as the speedup with HyperQ is amazing, and its only GK110 chip at this moment that can do it.. The GK 104 chip which 680 and 690 boards are made with doesnt have HyperQ possibility.

Im thinking, why didnt this get tested in the Titan reviews ? Its a huge performance boost, even downclocking the memory 500mhz.

To be perfectly honest, I admire your work, and regret not having a more powerful GK110...

Did it ever occur to you that maybe it WAS tested and failed? As commented before, Titans seems to be just K20X's which did not pass (this or other) test.... (see my former posts).

It could be. this is why I am running the titans extencively now the 2 following weeks as I have 14 days to return them. I am also checking what K20x will cost me, as I have special price availability. so well see.
