parallel linear system solver

[Paul J]

I have a beowulf cluster of 4 nodes(ok really small) and am looking for a
good and easy to implement linear solver(Ax=b). My problems are real,
symmetric, and only the upper triagle of A is stored. The matrices A and b
are created by the finite element method and need to solve for x. I need
to solve problems with more than 200,000 equations(6,000,000 non-zeros)
with the sparse matrix format being:

row# col# val

Any help is greatly appreciated,
Paul
