Options for a very large computation

I'm solving a 24-by-24 linear system symbolically. After getting what I want using NullSpace, I get a very complicated expression in 4 variables. When I try to Simplify the expression (before viewing) my system dies. Either I run out of memory, or, when I add TimeConstraints -> Infinity to the Simplify function, it takes "forever" (nothing after 8 hours). Two questions: (1) Any suggestions for how I can get more processing power, memory to do the calculations. (2) I have access to more power, but the programs need to be written in C++. Is there a way to convert the Mathematica code and the Simplify command, in particular, to C++ and run it offline? Thanks.
