VecCreateShared

Creates a parallel vector that uses shared memory.

Synopsis

int VecCreateShared(MPI_Comm comm,int n,int N,Vec *vv)

Input Parameters

comm -the MPI communicator to use
n -local vector length (or PETSC_DECIDE to have calculated if N is given)
N -global vector length (or PETSC_DECIDE to have calculated if n is given)

Output Parameter

vv -the vector

Collective on MPI_Comm

Notes

Currently VecCreateShared() is available only on the SGI; otherwise, this routine is the same as VecCreateMPI().

Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of thesame type as an existing vector.

Keywords

vector, create, shared
