Wait Analysis of Distributed Systems Using Kernel Tracing.
IEEE Transactions on Parallel and Distributed Systems(2016)
摘要
We propose a new class of profiler for distributed and heterogeneous systems. In these systems, a task may wait for the result of another task, either locally or remotely. Such wait dependencies are invisible to instruction profilers. We propose a host-based, precise method to recover recursively wait causes across machines, using blocking as the fundamental mechanism to detect changes in the cont...
