Good news: look up BLAS, and you will find a standard interface for
http://netlib.org/liblist.html
doing matrix computations. There are parallel implementations
available: Atlas, AMD ACML, Intel's math lib, etc etc.
If you want to extend it to mutilple machines, you can also look into
PBLAS as part of ScaLAPACK (above link) and/or it's Intel
implementation in Intel's MKL.

Bad news: Are you really inverting the matrix? You should probably be
doing something like LU decomposition.
