2 Components of the Software Stacks
The following table lists all the components currently available in the software stacks , specifying those that belong only to a subgroup of computers, and also the commercial and licensed software, which may be available only on one or a few sites.
Table 1: Current software components of the DEISA Common Production Environment (IBM indicates AIX, Linux/Power6, Linux/PowerPC IBM and Linux/BlueGene systems; IBM WBG indicates the same as 'IBM', but without the Linux/BlueGene systems

Naturally, this list of components is evolving and it is enriched according to the requirements of the users and the decisions of the administrators.
For each component the current default version is available in this way. In fact, several other versions of each component (either older or newer) are generally accessible. The default version is the one without a number, and the other ones are suffixed by a number (like fortran/12.1). We will describe below how to find out which ones are available and how to use a version other than the default one.
Please, note that for each subgroup of homogeneous computers, the versions are the same. This is of course essential to allow the user’s applications to have the same behaviour on the different homogeneous platforms. To guarantee this characteristic, an upgrade of a component (that is to say changing the default version for a newer one) or a removal of an old one, is always done in a coordinated and synchronized way across all the relevant sites. Please, note also that the default versions of a component can be different between the subgroups of homogeneous computers (for instance the default version of the NAG library can be different between the AIX IBM and HPC Linux SGI platforms, the netCDF library can be different between the AIX IBM and Super-UX NEC platforms, etc.).
