I'm becoming increasingly lazy in publishing stories.. sorry for that..
A good megacompilation is coming this week..
Anyway today is old news for installing Tesla Computing driver (196.28) see info (slide 35)
Tesla Compute Cluster (TCC)Driver
Enables Windows HPC on Tesla
Enables Tesla without a NVIDIA graphics card with Windows 7, Server 2008 R2, Windows Vista, Server 2008
Only Tesla 8-series, 10-series and 20-series supported
Only works with CUDA
Does not support OpenGL and DirectX
Available in beta now, release in Jan 2010
Enables the following features under Windows with CUDARDP (Remote Desktop)
Launch CUDA applications via Windows Services
No Windows Timeout issues
No penalty on launch overhead
KVM-over-IP enabled (CPU Server on-board graphics chipset enabled)
Teoretically is for Tesla and Windows 2008R2 64 bit only but I have succefussly installed on Windows 7 on GTX 275..
so installing compute driver is possible on Geforce
just locate NVWD.inf and add
under [NVIDIA_SetA_Devices.NTamd64.6.0]
%NVIDIA_DEV.05E6.01% = Section001, PCI\VEN_10DE&DEV_05E6
and under [NVIDIA_SetA_Devices.NTamd64.6.1]
%NVIDIA_DEV.05E6.01% = Section002, PCI\VEN_10DE&DEV_05E6
this is for GTX 275 for others locate in inf for your card..
Only supports CUDA at the moment (CUDA C(++)).. of course I have checked and PGI Fortran detects it so also CUDA Fortran..
OpenCL doesn't work currently but I think they will add support for it in 200 series..
DirectCompute I have not many hopes.. as device detection is for graphic devices and doesn't expose DirectX..
Have to test Badaboom for seeing if CUVID works and also what about CUDA video encoding via kernels is working (or CUVENC..)
I have to test if OptiX works (I hope but not graphic demos so save render to a file and check)
Also what about PhysX.. Theoretically should work as no interop with graphics is currently enabled at least this enables ATi rendering+PhysX work..
Have to test..
At least has no graphics API dependencies
Also what about other CUDA strong programs as Vreveal..
Last would be good if supported Nexus as I have ATI+Nvidia but Nvidia normal driver only enables CUDA if you extended desktop to *at least ONE Nvidia GPU*..
i.e. if you have 2 nvidias you can use Nexus but ATI+nvidia no work as extending desktop crashes GPU debugger and no extending it doesn't enable Nvidia driver (Windows 7 limitation?)..
Official response:
The Nexus Beta currently only officially supports the 195.62 driver from nvidia.com. Regarding support of the TCC driver, it is not currently supported, but Nexus debugging support using TCC is something we are considering for a future build.

Hi,
some questions:
I have tested on a GTX 275 (adding device id to the driver inf) with AMD 5850 as display good work..
(hmm I hope by saying that please don't block this possibilty similar to how are you going to block double prec potential by slowing down 4x on geforce fermi cards..)
By "Only CUDA is supported in this release" you mean OpenCL is supported right now?
I have tested OpenCL ocldeviceQuery and fails to search platform ID and is clear the driver doesn't include opencl.dll nor nvcompiler.dll..
Using that dlls from 196.34 don't work altough nvcuda.dll seems to have Khronos ICD entry points..
are you going to support OpenCL soon on Tesla driver?
I have not tested but are CUDA programs using textures mean to work? I assume yes altough a graphics feature..
Also what about for DirectCompute? i.e for DirectCompute apps not using graphics are you going to support it?
And finally Nexus, I have access to Nexus beta which supports by using two Nvidia cards in one PC debugging in one computer.. is this supported by using as display device an ATI card now one Nvidia card has not to have extended desktop
I hope you add support for Nexus for Tesla Computing driver in case it isn't supported right now..
