[Trilinos-Users] Epetra or Tpetra

[mrh1390 at gmail.com]

Dear All,


I want to solve a large LSE (10e5 unknowns with a sparse matrix of 20-30 non-zero components each row). Solving this LSE is repeated at each time-step with an updated coefficient matrix and RHS.



I want to get the most possible performance on a shared memory system. (a PC)

Is it better to use MPI or just enable the OpenMP during the CMAKE configuration?


Which package do you suggest for storing the CR matrix, Epetra or Tpetra? As I said, the matrix should be re-created every time-steps.



Thank you in advance,

Mohammad
