Compiler Support

QLogic MPI supports use of a number of compilers. These include:

„GNU gcc 3.3.x, 3.4.x, 4.0, 4.1, 4.2.x, and 4.3.x compiler suites

„PathScale Compiler Suite 3.0, 3.1 and 3.2

„PGI 5.2, 6.0. 7.1, 7.2-4, and 8.0-3

„Intel 9.x, 10.1, and 11.0

„gfortran 4.1.x

The PathScale Compiler Suite Version 3.x is now supported on systems that have the GNU 4.0 and 4.1 compilers and compiler environment (header files and libraries).

Setting Up Your Environment

Keep the following in mind when setting up the environment:

„The runtime and build environments must be the same. Compatibility between executables built on different Linux distributions cannot be guaranteed.

„You will need Administrator privileges on your machine(s).

„If using the rpm install method, make sure that all previously existing (stock) OpenFabrics RPMs are uninstalled. See “Uninstalling InfiniPath and OpenFabrics RPMs” on page 5-24for more information on uninstalling. The Installer tool will uninstall previous RPMs automatically before upgrades.

„It is possible to have a cluster running with different kernel versions. However, QLogic recommends and supports clusters where all nodes run equivalent software.
