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.
You can access the MPI standard in any of the following ways:
As online PostScript or hypertext on the web at the following URL:
As a journal article in the fall 1994 issue of the Journal of Supercomputing Applications
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.
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:
Another web page specific to PVM can be found at the following URL:
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.
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.
The PVM developers have established the following email alias, which they use to answer questions and provide support, as time permits:
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.
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:
Test and sample programs contained in the public domain releases that are not included in the Cray release
Papers and presentations by the PVM and MPI developers that describe PVM, MPI, and related products
Presentations from past PVM user group meetings
You can obtain information from netlib in the following ways:
Use the web, which allows you to obtain the files directly. This is perhaps the easiest and most convenient method. The PVM page at netlib is located at the following URL:
The MPI page at netlib is located at the following URL:
Send email to email@example.com (or firstname.lastname@example.org), and include the following in the Subject: line or message body:
send index from pvm3orsend index from mpi
Once you receive the index, similar send messages will return parts of PVM or MPI. This assumes the ORNL or AT&T host can determine how to return your email. If not, use anonymous ftp.
Use anonymous ftp from netlib2.cs.utk.edu.
Use anonymous rcp from netlib2.cs.utk.edu. For example:
rcp email@example.com:pvm3/your-local-fileorrcp firstname.lastname@example.org:mpi/your-local-file
You can use the following commands to obtain file lists:
rsh netlib2.cs.utk.edu -l anon ls pvm3orrsh netlib2.cs.utk.edu -l anon ls mpi
Use the xnetlib browsing tool (which you can obtain from netlib by using one of the preceding methods).
For access in Europe, use the duplicate collection in Oslo, as follows:
|X.400: s=netlib; o=nac; c=no|
For access in the Pacific, use the following address, located at the University of Wollongong, NSW, Australia:
