Hi All
With so many people who weren't here 12 months ago shunting units around between the CPU and GPU to compensate for various server problems. I thought it might be an idea to repost this warning from last year. It's just something to be aware of.

BEWARE - UNEXPECTED SIDE EFFECT OF USING RESCHEDULE PROGRAM

Hi All
Reschedule works at the client level but if you use it to move 6.03 (CPU) units to the GPU, when they are returned, the server still thinks they were crunched by the CPU. As a result the server thinks you have one hellishly hot CPU and allocates extra units to the CPU accordingly.

Therefore if you have a slow CPU driving a fast video card you are likely to find that the CPU is allocated an impossible number of units for it to complete on time. e.g. I have a 3GHz P4 driving a GTS-250. When the dam broke and I was able to download units again I was allocated 349 units to the CPU and 200 to the GPU. All this for a 1.5 day cache !! These 349 units represent about a months crunching for the poor old P4. When I used ReSchedule to move some of these units to the GPU, as soon as I restarted BOINC it immediately set about downloading more CPU units to make up for the ones I had shifted.

So, if your using ReSchedule to move CPU units to the GPU be aware of this and keep an eye on the number of units that the server allocates and uploads to the CPU. At the moment I'm having to run "No New Tasks" to avoid CPU overload.

Thanks for this - a timely reminder...
