Title Array Tracer: Ανάλυση και Οπτικοποίηση της Επίδοσης Παράλληλων Εφαρμογών
Alternative Title ArrayTracer: Parallel Performance Analysis and Visualization
Creator Zarras, Apostolos
Contributor Χ. Νικολάου
Abstract ArrayTracer is a parallel performance analysis and visualization tool. The design and implementation began 4 years ago, by Titos Saridakis (ArrayTracerThesis). During these years it's been developed and enhanced according to the modern ideas in the field of performance analysis tools. ArrayTracer's basic components are the following : Static Analysis Module. Trace Collection Module. Trace Analysis Module. Visualization Module The first two parts belong to the first phase of the tools implementation. The last two are the subject of this thesis. The analysis procedure takes place at Post-Mortem time. We tried to reduce the dilation introduced by ArrayTracer at the application's execution time, by producing reduced size trace records. These trace records do not contain timestamps. Besides that we reduced the number of trace records dumped. For each time consuming event we only produce one trace record instead of two. During the trace analysis procedure we must produce each process's event sequence and merge them in a total event sequence. To do that we construct logical timestamps according to dependencies that hold for the application processes. These dependencies result from the serial code executed, the interprocess communication and synchronization. To visualize the results we linked ArrayTracer with Paragraph. This was done with the implementation of a filter that transforms ArrayTracer's traces to PICL trace format events. We extended Paragraph with new displays that cover ArrayTracer's extra trace capabilities (Variables References, Subroutine/Function Calls).
