Does anybody now if it possible to program a 5d (4d in space) Implicit finite difference scheme. (The problem can parallalised in 1 of the space dimensions since there is no diffusion for the variable).  I was wondering if a gpu such as the teslo or new fermi could handle the memory requirement of such a problem since the 4d data structure eg a 4d array 50X50X50X50 would require alot of memory?  It would be very usefull if this is possible.

Thanks in advance to any replies.
