#define DIM   128

matmult.c

Test program to do matrix multiplication on large arrays.

Intended to stress virtual memory system.

Ideally, we could read the matrices off of the file system, and store the result back to the file system! You should define DIM to be large enough that the arrays don't fit in physical memory.
