Struct lamellar::BlockedArch

pub struct BlockedArch { /* private fields */ }

A grouping of PE’s forming a team using a “block” based distribution pattern.

PEs in the group are contiguous (with respect to their PE id, not necessarily their pyhsical location in the distributed envrionment).

examples

 use lamellar::{LamellarWorldBuilder,BlockedArch};

 let world = LamellarWorldBuilder::new().build();
 let num_pes = world.num_pes();

 //create a team consisting of the first half of PEs in the world
 let first_half_team = world.create_team_from_arch(BlockedArch::new(
    0,                                      //start pe
    (num_pes as f64 / 2.0).ceil() as usize, //num_pes in team
 ));

Implementations

impl BlockedArch

pub fn new(start_pe: usize, num_team_pes: usize) -> BlockedArch

Construct a new Block using a starting PE and the number of PEs to include in the Block

Examples

 use lamellar::BlockedArch;

 BlockedArch::new(
    4, //start pe
    5, //num_pes in team
 );
 // the team will consist of the 5 pes => 4,5,6,7,8
