Solves linear system of equations K u
= f
via the Jacobi iteration. We use a distributed symmetric CSR matrix K(sk
,id
, ik
) and initial guess of the solution is set to 0.
- Parameters
-
[in] | nnode | number of nodes and number of rows |
[in] | sk | vector non-zero entries of CSR matrix |
[in] | id | index vector containing the first entry in a CSR row |
[in] | ik | column index vector of CSR matrix |
[in] | f | distributed local vector storing the right hand side |
[out] | u | accumulated local vector storing the solution. |
