Probably not. numbercrunching is a purely userspace thing. By design, programs can do all sorts of math without any help from the kernel; the only thing the kernel is good for is I/O. If some particular application is doing lots of IO (use strace, maybe, ltrace or gdb also; compile with gcc -pg and use gprof), then its possible you could do something to optimize it .. but generally speaking I/O should be sparse and efficient, so if its not, its a bug in that program which should get patched :)
