Can CUDA be used simultaneously on the onboard Geforce 9400M and the dedicated 9600M GT chip of a Macbook Pro? If not, how is the switching managed? Does Mac OS X perform this switching automatically or is there a control panel applet for switching the graphics over?
You need to install the proper NVIDIA drivers for the video card on your machine. For us, it was the NVIDIA "GeForce 9400". So you skip the last steps in the post in #1 above, and instead follow this second procedure here: Help needed with Ubuntu 20.04 on iMac late 2009. It looks pretty similar to what you tried, so I think maybe your problem is you didn't do step 1.

I need to work with OpenGL 3.3 or 4.0 and I am using a MacBook6,1 (Intel Core 2 Duo, 4GB RAM, 2,26 GHz) with a NVIDIA GeForce 9400M graphic card. Is this card capable of performing OpenGL 3.3 or 4.0 things? From the cards specifics I coud not figure out if its possible!
We need to work with Visual Studio as well. Is it enough to run it on Parallels Desktop or better BootCamp, you have any experience?
Thanks for any help!greets Jules
The nVidia 9400M and the newer 320M support OpenGL 3.3 under Windows 7. However, running a project build using OpenGL 3.2 in Parallels Desktop and Win7 does not work for me. I suggest using BootCamp for the best OpenGL support.
Hi guys, I have a problem with my video card on Windows 7 that is driving me crazy...Usually in WIndows XP we have 2 monitors hooked up to a computer using the Nvidia Ge Force 9400 GT video card, we mount the monitors on a wall on top of each other (so monitor 1 is under monitor 2), if my mouse pointer is in monitor 1 and i go to the top of monitor 1 the pointer will then appear on the bottom of monitor 2....pretty simple...
The last thing on my list is the infamous NVidia GeForce 9400 card. Both machines are equipped with it. The corresponding proprietary driver is the 340xx series, which has been discontinued as far as I understand.
The Nvidia GeForce 9400M G is an integrated (onboard) graphics card for laptops without dedicated graphics memory. The card was introduced in October 2008 in conjunction with the new Apple MacBook, MacBook Pro, and MacBook Air products (called only 9400M). At the time of announcement it was the fastest mGPU (motherboard GPU) on the market.
The GeForce 9400M is the mobile variant of the GeForce 9400 chipset, which just launched last week. It's a single chip chipset with integrated graphics, giving it an inherent advantage over Intel's solution: it requires less motherboard real estate.
NVIDIA's chipset reduces the size of the motherboard but it also reduces power consumption. Intel's G35 was built on a 90nm and 130nm process as I just mentioned; while G45 is built on 65nm for the GMCH, the ICH is still 130nm (not 90nm as I originally assumed). NVIDIA's GeForce 9400M is a 65nm chip; with good power management it should be similar in power consumption to G45 if not lower.
NVIDIA's GeForce 9400M is smaller, consumes less power than G35 and at worst the same amount of power as G45, but on top of all of that it's a lot faster than anything Intel has to offer. Take a look at this chart from last week's GeForce 9300 review:
The GeForce 9400M is far from a hardcore gaming GPU; you can't run most new games at high quality settings and get smooth frame rates, but older games will actually run relatively well on this thing. A bunch of us still play Command & Conquer 3, and instead of setting up a bunch of systems we just game on laptops. The system requirements aren't tremendous but playing on anything with G35/G45 isn't exactly satisfying; the GeForce 9400M is enough to make that game look decent and play okay. And herein lies the biggest upgrade to the new MacBook and MacBook Pro: if you happen to have Windows loaded on these machines, the gaming performance of the integrated graphics is much improved. These aren't gaming machines but they are much better than before for less stressful titles. I'd suggest looking at the GeForce 9300 review for a good idea of where NVIDIA's gaming performance stands but you're basically looking at playability at 800 x 600 or 1024 x 768 depending on the detail settings of whatever title you're playing.
The GeForce 9400M, like Intel's GMA X3100 (the graphics core used in the previous generation MacBook), has no local framebuffer - instead it relies on carving out a portion of your system memory to use for its own needs. The GeForce 9400M uses the chipset's dual-channel DDR3-1066 memory controller, yielding around 17.1GB/s of memory bandwidth compared to the 10.7GB/s offered by the previous generation's dual-channel DDR2-667 memory controller.
Moving up to 40 windows, the gap between the GMA X3100 and the GeForce 9400M remains small but noticeable. But crank it up to 60 open windows and Expos stutters on the GMA X3100 while it's still fairly smooth on the GeForce 9400M. I suspect this may be due to the 9400M having 256MB of system memory set aside for it compared to 144MB by the GMA X3100, although both should be able to grow their memory partition as needed without incurring a terrible penalty.
At 80 windows the GMA X3100 is unbearable when activating Expos and both the MacBook's GeForce 9400M and the Pro's GeForce 9600M get choppy, but nowhere near as bad as the Intel solution. The 512MB GeForce 9600M will probably do a bit better with 80 windows but at 60 or less both of the NVIDIA solutions do well. With only a few windows open it's tough to tell the difference between the NVIDIA GPUs and the previous generation Intel offering, but keep a bunch of things open and you'll quickly appreciate the new mGPU.
Graphics card NVIDIA GeForce 9400 GT copes with the most difficult task on time. It is suitable for both computer games and watching videos, video and photo editors. NVIDIA GeForce 9400 GT has excellent performance and feature set for optimal performance at a low price.
The NVIDIA GeForce 9400M conserves battery life, but provides inferior performance. With general knowledge, one would expect an "integrated" graphics system that "borrows memory from the system" to be substantially slower than a graphics system with dedicated memory, but how much slower only can be unveiled with real-world tests, and most dramatically with games.
For Windows games, the MacBook Pro is limited to using its GeForce 9600M GT graphics processor, so there is no other way to test the GeForce 9400M without using it on the "non-Pro" MacBook. Consequently, the Gizmodo blog did exactly that in a "Hardcore Graphics Death Match" and concluded:
Chunktastic, indeed. Ultimately, the performance of the GeForce 9600M GT is massively superior to the GeForce 9400M, which is best reserved for use when battery life is more important than performance.

In terms of their specifications, the new GeForce 9300 and GeForce 9400 are nearly identical. As you can see in the spec list above, the only differences between the two are that the GeForce 9400 has a higher clocked GPU and shader cores. These attribute would obviously give the GeForce 9400 an edge in the 3D performance department, but as you'll see a little later, even the GeForce 9300 is far more powerful than any of Intel's current IGPs.
Based on the three-dimensional particle-in-cell (PIC) method and Compute Unified Device Architecture (CUDA), a parallel particle simulation code combined with a graphic processor unit (GPU) has been developed for the simulation of charge-exchange (CEX) xenon ions in the plume of an ion thruster. Using the proposed technique, the potential and CEX plasma distribution are calculated for the ion thruster plume surrounding the DS1 spacecraft at different thrust levels. The simulation results are in good agreement with measured CEX ion parameters reported in literature, and the GPU's results are equal to a CPU's. Compared with a single CPU Intel Core 2 E6300, 16-processor GPU NVIDIA GeForce 9400 GT indicates a speedup factor of 3.6 when the total macro particle number is 1.1106. The simulation results also reveal how the back flow CEX plasma affects the spacecraft floating potential, which indicates that the plume of the ion thruster is indeed able to alleviate the extreme negative floating potentials of spacecraft in geosynchronous orbit. be457b7860
