[3dem] GPU implementation of 3D projection matching in SPIDER

[Joachim Frank]

GPU implementations of 3D projection matching presents an extraordinary 
challenge since costly I/O needs to be minimized but, on the other hand, 
large data chunks need to be shared.  Ryan Bubinski in our group, 
working with Hstau Liao, has achieved a speedup of 104-fold, and has 
reported the implementation at the recent Hybrid Meeting in Lake Tahoe. 
 We are currently testing the GPU implementation and aim to interface it 
with SPIDER.  The software will be distributed with SPIDER once we have 
a publication in press.
