General Discussion

Hello all,

When doing MPI REDUCE on sparse matrices,
Does anyone know what this problem means ? and how to solve it ?

6 **** MPI_Reduce sparse  matrix: warning missing term in pattern 300
3 **** MPI_Reduce sparse  matrix: warning missing term in pattern 300
3 **** MPI_Reduce sparse  matrix: warning missing term in pattern 20
6 **** MPI_Reduce sparse  matrix: warning missing term in pattern 20

Thank you in advance,

Best regards,

Loïc,
