Hello,
I want to solve a system of sparse matrix equations where my left hand matrix is lower triangular matrix. Now this process is not as expensive as decomposition of the matrix. Here, only a back-substitution step is enough. Now my questions is that if I want to do this in parallel, how can I use PARADISO (specifically cluster interface) to solve this system of equations? Can I use just one of the steps of the solver to perform back-substitution? If yes, how?
This is my first time using PARADISO so kindly hep me with this and apologies if I said anything worng.
Thanks in advance,
Shailesh
