Has this changeset just been applied to Setiathome? or have they they changed
their limits some other way?
Up to today there was a 100 CPU and 100 GPU task limit in place, today after
maintenance there now seems to be a 100 CPU and 100 per GPU task limit in place,
ie with a CPU and GPU before you could have a maximum of 100 CPU & 100 GPU
tasks, now it you get 100 GPU tasks per GPU,
But my i5-3210M/GT650/Intel_Graphics_HD4000 instead of getting 100 Intel GPU
tasks, got an extra 100 Nvidia GPU tasks,
So it is possible this changeset is broken (if setiathome has applied it)
