lis_vector_set_size(3) - Linux man page

Name

lis_vector_set_size - assign the size of the vector

Synopsis

#include "lis.h"

LIS_INT lis_vector_set_size(LIS_VECTOR v, LIS_INT local_n, LIS_INT global_n);

Description

Assign the size of vector v.

Input

v: The vector
local_n: The size of the partial vector
global_n: The size of the global
vector

Exit Status

The following exit values are returned:

0: The process is normally terminated
unspecified: An error occurred

Note

Either local_n or global_n must be provided. In the case of the serial and multithreaded environments, local_n is equal to global_n. Therefore, both lis_vector_set_size(v,n,0) and lis_vector_set_size(v,0,n) create a vector of size n. For the multiprocessing environment, lis_vector_set_size(v,n,0) creates a partial vector of size n on each processing element. On the other hand, lis_vector_set_size(v,0,n) creates a partial vector of size m_p on the processing element p. The values of m_p are determined by the library.
