Just installed 190.38 Beta on Win. XP64 with 2 260s. Running good here. This has Cuda 2.3 also.

Ahh so they did finally get a cuda 2.3 out (even if its still in beta). I wonder if the project admins will just skip to cuda 2.3.

I wouldn't have thought so given they haven't rolled out 2.2 yet because of problems with some machines.

Here are some notes about the cuda 2.3 beta that I managed to find on the nvidia web site

Jun 20 2009, 06:17 AM

The CUDA Toolkit and SDK 2.3 betas are now available to registered developers. They include the following features:

The CUFFT Library now supports double-precision transforms and includes significant performance improvements for single-precision transforms as well. See the CUDA Toolkit release notes for details.

The CUDA-GDB hardware debugger is now available for all supported Linux platforms and is included in the CUDA Toolkit installer.

GPUs in an SLI group are now enumerated individually, so you can achieve multi-GPU performance even when SLI is enabled for graphics.

New support for fp16 <-> conversion intrinsics allows storage of data in fp16 format with computation in fp32. Use of fp16 format is ideal for applications that require higher numerical range than 16-bit integer but less precision than fp32 and reduces memory space and bandwidth consumption.

The CUDA SDK has been updated to include:
A new pitchLinearTexure code sample that shows how to effeciently texture from pitch linear memory.

A new PTXJIT code sample illustrating how to use cuModuleLoadDataEx() to load PTX source from memory instead of loading a file.

Two new code samples for Windows, showing how to use the NVCUVID library to decode MPEG-2, VC-1, and H.264 content and pass frames to OpenGL or Direct3D for display.

Updated code samples showing how to properly align CUDA kernel function parameters so the same code works on both x32 and x64 systems.

The Visual Profiler (packaged separately) includes several enhancements:
All memory transfer API calls are now reported

Support for profiling multiple contexts per GPU.

Synchronized clocks for requested start time on the CPU and start/end times on the GPU for all kernel launches and memory transfers.

Global memory load and store efficiency metrics for GPUs with compute capability 1.2 and higher.

The CUDA Driver for MacOS is now packaged separately from the CUDA Toolkit.
Support for major Linux distros, MacOS X, and Windows:

Fedora 10, RHEL 4.7 & 5.3, SLED 10.2 & 11.0, OpenSUSE 11.1, and Ubuntu 8.10 & 9.04
Windows XP/Vista/7 with Visual Studio 8 (VC2005) and 9 (VC2008)
MacOS X 10.5.6 and later (32-bit)

GPUs in an SLI group are now enumerated individually, so you can achieve multi-GPU performance even when SLI is enabled for graphics.

That's a nice feature, given all the confusion from new members that have SLI enabled and can't figure out why there aren't multiple WU's running. Kind of a "use SLI when playing a game, but not when crunching without having to do anything" sort of thing.

Anyone tested this new feature yet?

I`ve tested new drivers and I`m very satisfied - fast and fully stable (tested with other CUDA-software too). I wasn`t so satisfied since 178.24.

So at this moment I`d like to recommend 190.38 beta as best drivers for now.



It`s ofc my opinion and I just want to share it to the others. GL guys.

Just released as non beta :)

already found a bug, my 32-bit windows xp SP3 "9400 GT PCI" pc was doing something funky with pogo games, i rolled back the driver(June) and it's now corrected, but i don't have the power to report the bug to nvidia... can one of the reg. developer please get word to them... it wasn't java... it was the driver.

Hi, one question: did you notice some changes in perfomance ?
Unfortunately, installation of new 190.38 CUDA 2,3 was unlucky for me - new version doesn't recognize my second GTX260, so, I was roll them back to the previous.

Are you guys actually installing the CUDA 2.3 or Previous version of CUDA, I've never done that. All I've ever done is install whatever NVIDIA Drivers I needed to and ran the WU's. I've always thought the actual CUDA Program & Tools was just for Developers and not needed to run the WU's which I'm doing ...

I did install the new 190.38 Drivers on 7 Win XP Pro 64-Bit Box's this morning with no problems & running fine so far ... :)

yea we install the toolkit...

Jet, Did you install the 190.38 drivers on the second card as well?
The best way to make sure the drivers are installed on both cards is to update drivers via device manager.

zpm, No need to install the toolkit unless your developing a GPU app.

Bob

Thanks for afvice, drivers was installed for both...

I had nothing but issues with 190.38 on an i7 920 running 2x 8800GSs and Vista 64 SP1---until I upgraded a couple of days ago from 6.6.36 to 6.6.37....then the issues went away. Yesterday I moved back to RT, forced the driver and 3D performance and everything seems fine as far as Gpugrid goes. The main issue I have now seems to have appeared when I moved up to firefox 3.5.1, but it's not affecting the grid.

Put 190.38 on a Q6600 2x gpu rig running Vista 64 SP1 and haven't had any problems. I just checked and it's still running 6.6.28! lol

Ok, so now the question is this: Is it better on GPU Grid to use SLI or not?

Has anyone tested this yet?

I just installed 190.38 on one system and started it up so I will see if t works at all ... (3 minutes in and so far so good). Though I am not sure if we are running the newer application or not.

At this point the app is still delivering the cuda 2.1 DLL's. As per GDF's message thread it should get to cuda 2.2 by the end of this week.

My understanding is the SLI context is part of cuda 2.3, but I only got this from reading the release notes.

after upggrading yesterday evening i had the first big fat blue one after months of crunching without issues.. :(

as i can hear from my team-mates, there are several boxes which went down..

I have 2 Box's out of 7 that have returned nothing but error's since Upgrading to the 190.38's, the other 5 Box's only show 1 error total which could have been from something else.

I checked the 2 Box's in question and didn't see anything wrong with them but backed off the Shaders 25 Points & will see if they run better. Neither one of the Box's was returning errors until the Driver Upgrade so I would suspect something is amiss with the Driver on some Box's.

I checked the Task Manger & it shows the 190.38 Driver installed on Both Cards in both Box's but if they keep getting the error will do a complete uninstall & reinstall of the Drivers on both cards again.

I started another thread here for errors.

I too have one machine failing on all its wu. It has GTX260's, so maybe its limited to the G200 chipset as I have 4 others with GTS250's (G82 chipset) working fine.

Am I correct in that Cuda 2.3 has to have the 190.. drivers but Cuda 2.2 "as we are going to" works with the 185..186.. series drivers? I dont believe 190 drivers are necessary for Cuda 2.2 only for Cuda 2.3..
According to Nvidia release highlights.

I know the Mod. said 190.. was necessary but I wonder if he was mistaken.
