Support for manual parallelization of sequential C programs.
...The annotated program is then executed using a significant (but small) data set selected by the developer. The data collected is cross-referenced with the original source and can be interactively analyzed graphically to determine the best parallelization candidates and techniques.
This project is a tool for beginners to understand why a MPI program works or doesn't. It aims simple MPI codes, with a modest number of Processes. It is a real time view of an executing code, providing help even when the program deadlocks.
TraceX shows x server protocall communication for a selected program. This is the low level comminication used by xlib and others. The data can be shown as raw hex io, or formatted into the individual functions. This program meets the SFF guidelines.
SLO profiles the data locality in your program, and afterwards suggests refactorings that can improve that data locality, leading to fewer cache misses and faster execution.
