The PAPERS Library Execution Model
-
Communication is a side-effect of barrier sync.
-
All PEs together effect communication
-
Communication role of each PE is determined by that PE
-
Aggregate functions are computed in parallel within the "network"
-
Very low latency hardware and interface
-
No software layering
-
Barrier synchronization and voting operations supporting MIMD, SIMD,
and VLIW execution modes
