In this paper we describe the dproc (distributed /proc) kernellevel mechanisms and abstractions, which provide the building blocks for implementation of efficient, cluster-wide, and application-specific performance monitoring. Such monitoring functionality may be constructed at any time, both before and during application invocation, and can include dynamic run-time extensions. This paper (i)
... [Show full abstract] presents dproc's implementation in a Linux-based cluster of SMP-machines, and (ii) evaluates its utility by construction of sample monitoring functionality. Full version of this paper can be found at: http://www.cc.gatech.edu/systems/projects/dproc/
