  • Resolving the Deadlock

    To avoid deadlock situations, you can use the following approaches:

    • Reorder MPI communication calls between processes.

    • Implement non-blocking calls.

    • Use MPI_Sendrecv or MPI_Sendrecv_replace.

    • Use the buffered mode.

    The following code section leads to a deadlock in your original application:

    This section describes the steps you need to do before you start using the Intel® Trace Analyzer and Collector.

    Required Software

    To perform all the steps described in this tutorial, you need the following software installed on your system:

    Detecting and Resolving Errors

    To demonstrate the process of correctness checking of MPI applications, this tutorial uses two sample applications that have errors in the source code. All the sample applications eligible for correctness checking are available at: <install-dir>/examples/checking. You can use these samples to manually experiment with the functionality using the workflow described here.

    Instrumenting an Example with Data Type Mismatch

    To experiment with the data type mismatch example, copy the contents of the <install-dir>/itac/examples/checking/global/collective/datatype_mismatch/ directory to your working directory:

    $ cp -r <install-dir>/itac_latest/examples/checking/global/collective/datatype_mismatch/ ~
    $ cd ~/datatype_mismatch

    Then compile and run the MPI_Bcast example located in the directory using the following commands:
