Clearspeed offered a CPU architecture which, while similar in architecture to GPUs in terms of many parallel FPUs, goes beyond GPUs by having a more flexible architecture and many other scientifically useful properties, such as double precision Floating Point Units. In 2005, Clearspeed worked on porting GROMACS and has done some public demos. The later completed the port and we started testing its feasibility to be used in FAH. We launched this port in July 2005 and saw a significant increase over CPUs. However, as of 2006, we are turning our attention to the other platforms, and do not have any further updates on Clearspeed for the time being.
