BOINC Manager, when contacting LHC@Home 1.0, is now showing a request for NVIDIA GPU work units, but no GPU work sent.

GPU use does not show under computing preferences. I do use my GPU for Seti@Home.

Does anyone know what this means?

It's a BOINC feature, it does these requests to all projects, except for those projects that have a specific GPU option in Preferences.

...and we don't have a GPU version (yet). Next is a version
for MACs. Afterwards I have to complete my 0 ULP work to be
compiler independent then I either buy a compiler which supports
GPU or I rewrite the tracking code in C. Eric.

But why is Eric's system requesting GPU work? LHC Six Track does not have that option available in the Project preferences. I run GPU Tasks (NVIDIA) for other Projects but never see a GPU request for LHC Six Track.

Yours is probably already backed off to do that only once every 24 hours.
BOINC will by default ask every project that the user has attached to for Nvidia and ATI work, until the back-off is 24 hours.

It does this so the user doesn't have to change anything when the project decides to do work with a GPU. When they then release their application, it'll be picked up completely automatic when the back-off time is reached and depending of course on what GPU the user actually has. Otherwise it'll continue to back-off for another 24 hours.

To get to the 24 hour back-off period, there will have been several automated contacts. Do know that Updating the project manually will reset the back-off timer, and work requests for the GPU will be earlier again, increasing in time until it's back at 24 hours.

On projects where there is a GPU application, the back-end software will auto-detect this and enable the project preferences for the ATI and Nvidia GPU, depending on what application the project has released. Because this project has no GPU application at this time, the "Use ATI GPU" and "Use Nvidia GPU" options are disabled.
