Abstract

In a multi-chip multi-core computer system the indirect cost of thread context switch is affected by the architecture workload and scheduling strategy.In order to gain a more stable result the measurement for thread context switch should take account of these factors.Based on the analysis of the Lmbench's framework and working principle a new program called LTC was designed and implemented.Considering the requirements of thread performance measurement load models and scheduling policies were integrated into the LTC.The result shows that LTC is a good tool for analyzing the cost of thread context switch in a multi-core system.
