Blit - an open-source library for block iterative sparse linear solvers''

• Blit contains a set of highly efficient and open-source iterative sparse linear solvers that can handle multiple right-hand-sides (or block). Compared with the traditional linear solvers which solve for only solution at a time, blit can solve multiple solutions in a single solving process, thus is significantly faster than the conventional solvers. A block solver handles the following equation:

  A [x₁ x₂ x₃ ... x_M]=[b₁ b₂ b₃ ... b_M]

  where A is a N-by-N sparse (or full) matrix with either real or complex values, b_i and x_i are the right-hand-side and solution vectors, respectively.
