I doubt it, though the graphic card is not too powerful (this part of the
test failed on the "ATI Radeon HD 6630M"). The computer has 4GB of memory (and
freshly rebooted), and the card has (according to wikipedia) 1GB of mem.

global_size,local_size: (2304,) (128,)
Not so big, so... But I've seen a few problems on the ATI card - sometimes I
get into a state where opencl initialization becomes impossible, and I have to
reboot. Not sure if a soft reset is possible. But that's a different issue.
