I have a system that has both the Intel® Compilers and the Intel® MPI Library. I'm trying to run an Intel MPI job with mpirun but I'm hitting the following errors:
line 96: /opt/intel/composer_xe_2013_sp1/mpirt/bin/intel64/mpivars.sh: No such file or directory
Furthermore, when I try mpirun -V, it returns this:
If your MPI program sends messages of drastically different sizes (for example, some 16 byte messages, and some 4 megabyte messages), you want optimum performance at all message sizes. This cannot easily be obtained with a single DAPL* provider. This is due to latency being a major factor for smaller messages, but bandwidth being more important for larger messages, and providers often making a tradeoff to improve one or the other. The Intel® MPI Library, as of Version 4.1 Update 1, now supports up to three providers for a single rank of your job.
- Intel(R) C++ Composer XE 2013 SP1 for Linux*
- Intel(R) Fortran Composer XE 2013 SP1 for Linux
- Intel(R) Cluster Studio XE 2013 SP1
If you use
-mkl=cluster on your compilation line, but do not have the environment for Intel® Cluster Studio XE 2013 SP1 setup and installed, you will get linker errors like so:
Best Known Method
Running an MPI program in symmetric mode on an Intel® Xeon® host and an Intel Xeon Phi™ coprocessor may deadlock in specific cases due to the heterogeneous precision in replicated control flow calculations. The advice is to determine the control flow only on one master MPI process.
Intel MPI applications can be executed on multiple combinations of Intel Xeon processors and Intel Xeon Phi coprocessors. Four different execution models are supported:

The Intel® MPI Library includes an Automatic Tuner program, called mpitune. You can use mpitune to find optimal settings for both a cluster and for a specific application. In order to tune a specific application (or to use a benchmark other than the default for a cluster-specific tuning), mpitune needs a way to determine the performance from a run of the application. By default, the runtime of the application will be used. But depending on the application, this could be inaccurate. You might want only the time for a specific portion of the application, or you might want a different mea
