"Memory Errors Debugging for MPI Applications with the Memchecker tool"
Presented by Mr. Shiqing Fan
The presentation will be delivered over EVO:
The Meeting password is: "HPC-Europa2"
Memory segmentation faults or irregular uses are difficult to
be detected in MPI parallel applications. For this specific purpose, new
memory debugging tools are developed for detecting memory problems. With
integrating the tools into Open MPI as MCA frameworks, developers and
users may find potential memory errors or problems that violating the
MPI standard, such as memory violations, buffer overrun, and
inconsistent parameters. Furthermore, the memory checking tools and
frameworks may also help improve the performance of MPI parallel
applications by detecting whether data communication is efficient or
not. The new memory checking tools may also be used and extended in
other projects or debuggers to perform different memory checks.
