Profiling under UNIX by patching

Profiling Under UNIX by Patching

Profiling under UNIX® is done by inserting counters into programs either before compiling, during compiling, or during assembly. A fourth type of profiling involves monitoring the execution of a program, and gathering relevant statistics during the run. This paper looks at this method and an implementation of it, and discusses its advantages and disadvantages.

Libckpt: Transparent Checkpointing under UNIX

Checkpointing is a simple technique for rollback recovery: the state of an executing program is periodically saved to a disk le from which it can be recovered after a failure. hile recent research has developed a collection of powerful techniques for minimizing the overhead of writing checkpoint les, checkpointing remains unavailable to most application developers. In this paper we describe lib...

Wux: UNIX Tools under Windows

Wux is a port of Unix tools to the Microsoft Windows environment. It is based on a library providing a Unixcompatible set of system calls on top of Windows. Unix-derived tools run in parallel, communicating using the Unix pipe abstraction. All processes are run within an application template that gives them basic Windows compatibility such as input and output windows and an icon. The performanc...

Adaptive Block Rearrangement Under UNIX

An adaptive UNIX disk device driver is described. To reduce seek times, the driver copies frequently-referenced blocks from their original locations to reserved space near the center of the disk. Block reference frequencies need not be known in advance. Instead, they are estimated by monitoring the stream of arriving requests. Measurements show that the adaptive driver reduces seek times and re...
