Name : tiptop Product : Fedora EPEL 7 Version : 2.3 Release : 1.el7 URL : http://tiptop.gforge.inria.fr/ Summary : Performance monitoring tool based on hardware counters Description : Hardware performance monitoring counters have recently received a lot of attention. They have been used by diverse communities to understand and improve the quality of computing systems: For example, architects use them to extract application characteristics and propose new hardware mechanisms; compiler writers study how generated code behaves on particular hardware; software developers identify critical regions of their applications and evaluate design choices to select the best performing implementation. We propose that counters be used by all categories of users, in particular non-experts, and we advocate that a few simple metrics derived from these counters are relevant and useful. For example, a low IPC (number of executed instructions per cycle) indicates that the hardware is not performing at its best; a high cache miss ratio can suggest several causes, such as conflicts between processes in a multicore environment.
Tiptop is a performance monitoring tool for Linux. It provides a dynamic real-time view of the tasks running in the system. Tiptop is very similar to the top utility, but most of the information displayed comes from hardware counters.
