Intel® MPI Library supports the following debuggers for debugging MPI applications: GDB*, TotalView*, and Allinea* DDT. Before using a debugger, make sure you have the application debug symbols available. To generate debug symbols, compile your application with the -g option.
This section explains how to debug MPI applications using the listed debugger tools:
Many problems with using the Intel® MPI Library are related to wrong cluster configuration. As a general step, to make sure that your cluster is properly configured and is ready for using the Intel MPI Library, you can use the Intel® Cluster Checker, which can perform the cluster health check. This check will help you protect from some commonly occurring issues.
Intel® MPI Library provides tight integration with the Intel® Trace Analyzer and Collector, which enables you to analyze MPI applications and find errors in them. Intel® MPI Library has several compile-time options to simplify the application analysis.
Intel® Trace Analyzer and Collector is available as part of the Intel® Parallel Studio XE Cluster Edition. Before proceeding to the next steps, make sure you have the product installed.
