Parallel conjugate gradient for poisson equationsHi friends
I am working on implementation of conjugate gradient method specifically for sparse matrix, which arises after discretisation of Poisson equation. i implemented ILU0 preconditioner. Now i am trying to parallelise the code using MPI command.. In current code needs to exchange information three times among various processor in each iteration of CG , which takes lots of time. can anyone please suggest me some way to reduce number of data exchange per iterations. Regards RV |

i got it..i did it... :)
if anyone need the source code for CG,PCG, parallel CG and parallel PCG for solving poisson equation . please mail me rah00002004[at]gmail.com . |
