The Portland Group (PGI) is a provider of high performance compiler products. It is of interest to GPU programmers because of its PGI Accelerator features which make GPU programming just a bit easier.

▶ Softenv FAQ?

The information here is applicable to LSU HPC and LONI systems.


A user may choose between using /bin/bash and /bin/tcsh. Details about each shell follows.


System resource file: /etc/profile

When one access the shell, the following user files are read in if they exist (in order):

  1. ~/.bash_profile (anything sent to STDOUT or STDERR will cause things like rsync to break)
  2. ~/.bashrc (interactive login only)
  3. ~/.profile

When a user logs out of an interactive session, the file ~/.bash_logout is executed if it exists.

The default value of the environmental variable, PATH, is set automatically using SoftEnv. See below for more information.


The file ~/.cshrc is used to customize the user's environment if his login shell is /bin/tcsh.


SoftEnv is a utility that is supposed to help users manage complex user environments with potentially conflicting application versions and libraries.

System Default Path

When a user logs in, the system /etc/profile or /etc/csh.cshrc (depending on login shell, and mirrored from csm:/cfmroot/etc/profile) calls /usr/local/packages/softenv-1.6.2/bin/ to set up the default path via the SoftEnv database.

SoftEnv looks for a user's ~/.soft file and updates the variables and paths accordingly.

Viewing Available Packages

The command softenv will provide a list of available packages. The listing will look something like:

$ softenv
These are the macros available:
*   @default
These are the keywords explicitly available:
+amber-8                       Applications: 'Amber', version: 8 Amber is a

Managing SoftEnv

The file ~/.soft in the user's home directory is where the different packages are managed. Add the +keyword into your .soft file. For instance, ff one wants to add the Amber Molecular Dynamics package into their environment, the end of the .soft file should look like this:



To update the environment after modifying this file, one simply uses the resoft command:

% resoft

The command soft can be used to manipulate the environment from the command line. It takes the form:

$ soft add/delete +keyword

Using this method of adding or removing keywords requires the user to pay attention to possible order dependencies. That is, best results require the user to remove keywords in the reverse order in which they were added. It is handy to test out individual keys, but can lead to trouble if changing multiple keys. Changing the .soft file and issuing the resoft is the recommended way of dealing with multiple changes.


  • Make sure you have softenv set to match the any libraries with the version of the compiler you want to use. Below is an example matching use of the PGI 6.1 compilers with the MVAPICH 0.98 library:
  • +portland-6.1
  • Choose the compiler command name from the table below:
  • Language Serial Codes MPI Codes OpenMP Codes Hybrid Codes
    Fortran pgf90 mpif90 pgf90 -mp mpif90 -mp
    C pgcc mpicc pgcc -mp mpicc -mp
    C++ pgCC mpiCC pgCC -mp mpiCC -mp
  • Note: the libraries used with the MPI compiler commands are controlled by the MPI softenv key specified in the .soft file.


  • Documentation is available on line. This includes User Guides, FAQ, and language references.
