I had to move processing to another computer and SETI@Home no longer runs the video display. This computer is an Intel Core i7 64-bit processor, 8Gb RAM and an nVidia GeForce GTS 250. Einstein@Home shows its video display when running. SETI processes data, just no display. No big deal, but I miss seeing it. Thanks, Turner |

When using the GPU SETI@home the screen saver will not work - its just too much for the GPU to cope with. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Okay, thanks for the response. Should I upgrade the video card, it is kind of wimpy? With my current setup, I assume more processing gets done without the screen saver and that is the preferred method? Turner |

...its just too much for the GPU to cope with. Which isn't true, by the way, and never has been. CUDA can work really well together with any (OpenGL) screen saver, and it shows it when you run stock CPU apps which do come with the graphics applications. You can then run stock GPU apps and see the screen saver for any Seti task running on the CPU. Most non-BOINC related OpenCL applications on Intel HD, AMD and Nvidia are also capable of showing intricate 3D graphics while doing calculations. It's different parts of the graphics processor that's being used. As an example, the Einstein CUDA and OpenCL applications come with a graphics application. These run without problems side by side. |

Turner, I wouldn't upgrade a video card just to run a screen saver. However I would upgrade one if the old one broke, or I needed it for work, or wanted to save a bit on my fuel bill, or wanted to crunch a bit faster. More modern cards are faster and tend to use less power. Running a screen saver does eat into the resources available, thus slowing the processing down which is why most, if not all, the uber-crunchers don't even bother trying.

I have the same issue with the SETI screen saver. In the past I was able to run both Einstein and SETI on my dual processor G4 and 2 screens. I would start them up and then have each program's screen saver on, one on each screen. Worked that way for a couple of years and then with one of the bionic updates that feature seems to have gone away. I could see one or the other, but not both, depending on which task was selected. Now I can see Einstein as a screen, when available, but not SETI. Dual ,867Mhz PPC G4, 2GB RAM and ATI Radeon 9000 Pro video card. Mostly used to run these programs and little else these days. Not a huge issue, but I too liked the original feature. |
