Nvidia Nexus beta1 GPU debugger shipped!

Hi,
I just get access to Nexus beta 1 dated 2-12-2009!


Below is readme:
NVIDIA Code-name Nexus 1.0 Beta 1 Notes 12.02.09
Requirements
To use the Nexus Debugger for hardware debugging CUDA C or HLSL code, you will need to use two machines, a host (with Visual Studio) and a target with a supported GPU (for running your application) in order to debug remotely over a normal TCP/IP network connection.
To use only the Nexus Analyzer or Graphics Inspector, you may either use a single machine with a single supported GPU installed, or use it remotely as described for the debugger. If using a single machine, your ‘host’ and ‘target’ machine are the same physical machine. More information is available in the Nexus Knowledge Base accessible by signing in through www.nvidia.com/nexus.
Host machine:
 Operating System: Windows 7 or Vista SP1, 32 or 64-bit.
 GPU: Any DX10-capable GPU
 Visual Studio: Visual Studio 2008 with Service Pack 1 (Standard edition or above)
 Other Software: .NET framework 3.5 with Service Pack 1
 Optional: CUDA SDK, DirectX SDK (Mar 2009 or Aug 2009)
Target machine:
 Operating System: Windows 7 or Vista SP1, 32 or 64-bit.
 GPU: An NVIDIA G92 or GT200 based GPU (GeForce, Quadro, or Tesla)
 Other Software: .NET framework 3.5 with Service Pack 1
 Optional: CUDA SDK, DirectX SDK (Mar 2009 or Aug 2009)
Download and Installation steps
1. Sign-in to the NVIDIA Nexus Support site. You can get here by signing in from www.nvidia.com/nexus.
2. Go to the Downloads page.
3. Download a host installer. You will install this installer on the machine that has Visual Studio on it.
o For 32-bit: NVIDIA_Nexus_Host_Win32_Beta1_12_01_2009
o For 64-bit: NVIDIA_Nexus_Host_Win64_Beta1_12_01_2009
4. Download a monitor installer. The monitor is the debug ‘server’ you will connect to, either on another machine or on your existing machine.
o For 32-bit Monitor: NVIDIA_Nexus_Monitor_Win32_Beta1_12_01_2009
o For 64-bit Monitor: NVIDIA_Nexus_Monitor_Win64_Beta1_12_01_2009
5. Download the display driver required by Nexus.
a. 195.62 driver (32-bit): http://www.nvidia.com/object/win7_winvista_32bit_195.62_whql.html
b. 195.62 driver (64-bit): http://www.nvidia.com/object/win7_winvista_64bit_195.62_whql.html
6. Install the driver on the ‘target’ machine (that has a GPU with a G92 or GT200 chip) but do not reboot.
7. Install the Nexus Monitor installer on the same ‘target’ machine in Step 4 (that has the G92 or GT200 GPU in it).
8. Install the Nexus Host on the 'host' machine, where Visual Studio 2008 SP1 is installed.
9. Read the release notes by choosing Start | All Programs | NVIDIA Nexus 1.0 | Release Notes
10. Open the User Guide by choosing Start | All Programs | NVIDIA Nexus 1.0 | User Guide and follow all the steps under the “Walkthroughs” section. This is important as it will validate that you are able to debug and analyze with the samples provided.
If you would like to use your existing project with Nexus, please read “Migration from An Existing Project” in the User Guide.
Notes and Known Issues
- Samples: Nexus ships with samples located (by default) in C:\ProgramData\NVIDIA Nexus 1.0.
- Documentation: Nexus includes a User Guide located on your machine (after installation) at Start | All Programs | NVIDIA Nexus 1.0 | User Guide.
- Release Notes: Choose Start | All Programs | NVIDIA Nexus 1.0 | Release Notes to view the full release notes.
- Graphics shader debugging is only supported when the ‘host’ machine is physically a separate machine than the ‘target’ machine. Attempting to do shader debugging on the same machine as the ‘host’ machine will hang your system.
- Note: Hardware source debugging (either CUDA kernels or HLSL shaders) is only supported when your ‘host’ machine is physically separate machine than your target machine and they remotely communicate over TCP/IP. Information on experimental single-machine Debugger support (for machines with 2 GPUs) for CUDA C debugging only is available in the Nexus Knowledge Base (sign-in through www.nvidia.com/nexus)
- Note: If using Vista, you can check if you have SP1 installed by opening the Control Panel, clicking on the System icon, and looking for the words “Service Pack 1” in the “Windows edition” section.
- Note: Installer: Some commands are executed that bring up the command prompt during installation.
- Known issue (Stability): Analysis: Starting an Analysis session while stopped at a breakpoint causes the system to crash.
- Known issue (Stability): Under some circumstances, using Stop Debugging (Shift + F5) when halted at a breakpoint in a CUDA C kernel will cause your target machine to hang. The workaround is to remove all breakpoints, and hit Continue (F5) before stopping your debug session.
