Open-MPI over MOSIX: paralleled computing in a clustered world | | Adam Lev-Libfeld

29 Jun 2019 | | Abstract: | Recent increased interest in Cloud computing emphasizes the need to find an
adequate solution to the load-balancing problem in parallel computing --
efficiently running several jobs concurrently on a cluster of shared computers
(nodes). One approach to solve this problem is by preemptive process migration
-- the transfer of running processes between nodes. A possible drawback of this
approach is the increased overhead between heavily communicating processes.
This project presents a solution to this last problem by incorporating the
process migration capability of MOSIX into Open-MPI and by reducing the
resulting communication overhead. Specifically, we developed a module for
direct communication (DiCOM) between migrated Open-MPI processes, to overcome
the increased communication latency of TCP/IP between such processes. The
outcome is reduced run-time by improved resource allocation. | | Source: | arXiv, 1907.0194 | | Services: | Forum | Review | PDF | Favorites | |
