This work unit
p3-IBUCH_0512_pYEEI_long_100505-16-40-RND9133_1

shows 76,34% CPU usage with increasing trend after 3 hours runtime on a GTX470 - and the completion gauge shows not more than 35%. 'GPU Load' shows abaout 52%.
Are we on the way to CPUGrid or is that only a very rare kind of WU? For units on this card came to a maximum of 33% for CPU.
SWAN_SYNC=0 is set, BM is restricted to 7 cores for the real CPU projects.
Did anyone else see this high percentage for CPU?

Edit: Driver is 197.75 under Vista 64

the _long WUs are double the size of the others.

SWAN_SYNC=0 is set
that setting tells the WU to capture and use a complete thread

Thanks - Steve
