Today, "A dedicated data collection drive to map the various coastal villages, fishing harbours, jetties and landing points has been undertaken, in addition to continuous profiling
of fishing activity along the West coast," said Sinha.
The Digital Continuous Profiling Infrastructure provides an efficient and accurate way of answering such questions.
To gather these profiles, the Digital Continuous Profiling Infrastructure periodically samples the program-counter (PC) on each processor, associates each sample with its corresponding executable image, and saves the samples on disk in compact profiles.
Since significant fractions of most executable images consist of symbol tables and instructions that are never executed, profiles are typically smaller than their associated executables by an order of magnitude, even after days of continuous profiling. Although disk space usage has not been a problem, we have also designed an improved format that can compress existing profiles by approximately a factor of three.
The Digital Continuous Profiling Infrastructure transparently collects complete, detailed profiles of entire systems.
