I'm not sure whether this group is still active, but just giving a try.
need to find inverse of large dense matrix (about 3000*3000 complex or
more). I have tried to use ATLAS (lapack and blas). But it is
(I assume these codes are not cash optimized, and degrade performances, or at-last my implementation.)
understanding is, when matrix size is very large cash performance
becomes critical. Could anyone provide a optimized code for very large
matrix inversion problem.
It need not to be a GPU code, A CPU code it also fine.
PS : (I need to inverse matrix directly. to find Greens function)
