Detailed Description

template<typename T>
class libMesh::DistributedVector< T >

Distributed vector. Provides an interface for simple parallel, distributed vectors. Offers some collective communication capabilities. Note that the class will sill function without MPI, but only on one processor. This lets us keep the parallel details behind the scenes.

Author:: Benjamin S. Kirk, 2003

Change the dimension of the vector to N. The reserved memory for this vector remains unchanged if possible, to make things faster, but this may waste some memory, so take this in the back of your head. However, if N==0 all memory is freed, i.e. if you want to resize the vector and release the memory not needed, you have to first call init(0) and then init(N). This cited behaviour is analogous to that of the STL containers.

On fast==false, the vector is filled by zeros.
