Hi all,
I am modifying step-17 to do multiscale modeling. My goal is different from
the step-17, i.e., I don't want to store the matrix in distribution.
let's consider matrix-vector multiplication problem, [A]{u}={b}, in which
[A] has already been obtained as a full matrix without distribution, and
the rhs vector {b} needs to be assembled with distribution. My problem is
how to obtain the components of the rhs vector {b}, or how to convert the
distributed vector to a normal vector without distribution? I really need
this even of it is not efficient.
Any one can help? Thank you very much!
Best,
Chenchen
