[Trilinos-Users] Best direct solvers

[John R. Cary]

Hi Eric,

In this regard, suppose my matrix corresponded to differences in only one
direction (e.g., only x, not y, z).  On each line, I could do a direct 
tridiagonal
solve if I were in serial.  What would be best for parallel in this case?

Thanks...John
