Rosetta Admins know the power of gpu (see, for example, Poem@home project), but you are right, it's VERY difficult to implement.
This is the reason i hope for AVX/AVX2 extensions, probably easier to implement and with an immediate gain (look at the first 100 cpus in Statistics)

I'd not heard of Free-DC before but looking at it now, it seems very similar to a hundred other distributed computing team websites (with the caveat that Free-DC says it is open to everyone). What selection criteria would you suggest the Rosetta administrators use to select useful links while still keeping the list to a manageable size?

There is an android version, but it is only used for very limited numbers of tasks. So, at present, there must not be any tasks created for android.

Now that Simap has ended, I've added Rosetta to my Samsung Galaxy S4. Awaiting tasks to come through. Nothing over the last week, so only WCG going through now.
