5.7. Additional resources

Along with the standard support described in the preceding sections, users of PVM and MPI have a variety of other resources available to help them use these products. These resources should supplement, not replace, standard Cray support. Users are encouraged to use Cray support when they encounter what may be a PVM or MPI bug. However, these other resources can be helpful in gaining a better understanding of PVM and MPI and how they can be used. The following sections describe some of these resources.

5.7.1. MPI standard

You can access the MPI standard in any of the following ways:

5.7.2. News groups

The comp.parallel.pvm and comp.parallel.mpi Internet news groups focus on PVM and MPI and related products. The PVM and MPI developers use these news groups to announce new releases of the products and to discuss related topics, such as the PVM User Group meeting (see Section 5.7.5). Users are also free to use the news groups to interact with one another by responding to postings made by others.

To access comp.parallel.pvm or comp.parallel.mpi, you must have access to the Internet and a news reader program. If necessary, contact your site administrator for additional information.

5.7.3. Web servers

Several PVM-related web servers are available. There is one for netlib (see Section 5.7.7) that includes the PVM source code, other material on PVM, and additional software packages and subjects. The URL for this server is as follows:

http://www.netlib.org/pvm3/index.html

Another web page specific to PVM can be found at the following URL:

http://www.epm.ornl.gov/pvm/pvm_home.html

5.7.4. MPI user group meetings

You can obtain information about upcoming MPI developers conferences and user group meetings through comp.parallel.mpi or through the MPI web page listed in Section 5.7.1.

5.7.5. PVM user group meetings

There have been several PVM user group meetings held in the past, and there are plans to continue them in the future. These meetings have been quite successful, attracting a wide range of presentations from the PVM development team, vendors working on PVM, and users working on PVM-related tools or using PVM in applications.

Announcements of PVM user group meetings are posted in the news group comp.parallel.pvm.

5.7.6. PVM email support

The PVM developers have established the following email alias, which they use to answer questions and provide support, as time permits:

pvm@msr.epm.ornl.gov

Users first try Cray support or contacts when asking questions. This email address, however, can be used when needed.

The MPI Forum email discussions, and both current and earlier versions of the standard, are available from the netlib server. For more information about netlib, see the following section.

5.7.7. netlib source

Public domain versions of PVM and MPI are available from a source called netlib. If your site is using the versions of these products contained in MPT, you will not need to obtain the source code from netlib. However, the following additional resources available from netlib might be useful:

You can obtain information from netlib in the following ways:
