  1. PERFORMANCE TESTING OF PVM AND MPI WITH THE MOSIX PROCESS MIGRATION IN A DISTRIBUTED COMPUTING ENVIRONMENT Mr. Ye MyintNaing [yemyintnaing@gmail.com] STATE MARINE TECHNICAL UNIVERSITY, ST.PETERSBURG JINR, LIT 16-21 July,2012 Dubna

  2. What is MOSIX? An operating system-like management system for distributed-memory architectures, such as clusters and multi-clusters, including remote clusters on Clouds Main features: • Provides a single-system image. • Automatic resource discovery • Dynamic workload distribution by process migration

  3. Kernel layer of MOSIX

  4. MOSIX Direct File System Access • Provides a unified view of all files and all mounted FSs on all nodes, as if they were within a single FS • Makes all directories and regular files throughout a MOSIX cluster available from all the nodes • Provides file consistency from different nodes by maintaining one cache at the server (disk) node • Parallel file access by process migrate

  5. Process migration

  6. Dynamic load balancing

  7. PVM vs MOSIX

  8. MPI vs MOSIX

  9. Conclusions • High performance of a cluster on completely parallel tasks, • MOSIX preemptive process migration mechanism and its load balancing sheme. • For performance increase on strongly connected tasks it is necessary to increase speed of a network, for example using Gigabit Ethernet or Myrinet. • MOSIX don't manage to be reached a gain in performance of single process
