NAME¶

vec - vector in distributed environment (rheolef-6.1)

SYNOPSYS¶

STL-like vector container for a sequential or distributed memory machine model. Additional operation fom classical algebra.

EXAMPLE¶

A sample usage of the class is:

     int main(int argc, char**argv) {
        environment distributed(argc, argv);
        vec<double> x(100, 3.14);
        dout << x << endl;
     }
 

IMPLEMENTATION NOTE¶

Implementation use array<T,M>.
