摘要:
This paper describes the performance analysis of the local area network (LAN) of workstations for distributed computing applications. Several application programs represented in a task graph format are scheduled by the user workstation (master) for parallel execution in the idle or lightly loaded processors (slaves) in LAN. The partial results are collected by the master station to synchronize the operation of slave nodes. The system performance is characterized by the network speedup considering scheduling time, network load and size, communication time, TCP/IP communication overhead, task execution, and synchronization time. The sequential and parallel execution times and the performance degradation factors were measured during the implementation for various network loads. The measurement values and theoretical results have shown that the system performance is degraded mostly by the TCP/IP overhead (0.2 s), the network size, and the network load.
