MPI Checking

Included in Intel Trace Analyzer and Collector is a unique MPI correctness checker to detect deadlocks, data corruption, or errors with MPI parameters, data types, buffers, communicators, point-to-point messages and collective operations. By providing checks at run-time, and reporting the errors as they are detected, the debugging process is greatly expedited. The correctness checker also allows debugger breakpoints to help in-place analysis but has a small enough footprint to allow use during production runs. The true benefit of the Intel Trace Analyzer and Collector Correctness Checker is the potential to scale to extremely large systems and the ability to detect errors even among a large number of processes. The checker can be set to view deadlocks regardless of fabric type.

Instrumentation and Tracing

Intel Trace Analyzer and Collector specializes in low intrusion binary instrumentation. It can create and add this instrumentation to existing statically and dynamically linked binary executables to allow automatic monitoring of MPI as well as function entry and exit points. This includes the capability of tracing and recording performance data from parallel threads in C, C++ and Fortran.

Intel Trace Analyzer and Collector support both MPI applications and distributed non-MPI applications in C, C++, and Fortran. For applications running with Intel® MPI Library this includes tracing of internal MPI states.
