During the month of March the deadline for the Project Preparation report and presentation. The goal of this module was to justify the research done and to prove the feasibility of the project.
During the 3rd meeting the MPI socket organisation was presented to David, showing a new orientation of the communication. Mainly the discussion was about the report, and what to write in it.
But also a set of tests, from the earlier MPI course, was discussed, including 3 simple codes and 1 more complex one:
- calculating PI
- A message in a ring
- The traffic model
The main features for the software are the communication information (general statistics to find missing calls to MPI_Wait for example), the data display to show what data are sent and where they are stored to. Finally the last feature is a synchronised view of the communication, equivalent to a step by step action in a debugger, but at a MPI call level rather than a C or assembly one.
Few innovations were made for the 4th meeting. The report was due few days after. Nonetheless some goals were discuss. The project will provide a framework composed of a library (the profiler part) and an executable (the interface). The goal is to provide a real time global view of the program and it aims modest MPI programs with few processes. As it is only an information tool no performance is needed, but effort will be made to insure at least memory management.
