PVM currently supports Fortran and C programs on a variety of machines (workstations to supercomputers) and a limited number of operating system/network environments. How do I get it? The current version is obtained by sending a request to the netlib mail daemon. Mail (in the Subject: line or message body) to netlib@ornl.gov (or research.att.com): send index from pvm will get you info for pvm 2.4.2. send index from pvm3 will get you info for pvm3.1. Similar "send" messages will return parts of PVM. This assumes the ORNL (Oak Ridge National Lab or AT&T) host can figure out how to return your email. Do not assume reliability. Caveat Receptor. What is XPVM? Back when PVM was being developed, the in-house version of PVM was known as PVM1.0. This version was not released to the public. PVM1.0 had a X interface console which gave some basic stats about PVM. Many of the features mentioned in the paper "Network Based Concurrent Computing on the PVM System" were not included in the public release of PVM. The version released to the public domain are versions PVM2.0 and greater which have no X interface. One reason why XPVM was not released in PVM2.0 was that many of the features in XPVM were not robust enough to be included in a general release (see the paper by Grant and Skjellum, "The PVM Systems: An In-Depth Analysis and Documenting Study - Concise Edition"). XPVM spun off into two projects: HeNCE Heterogeneous Network Computing Environment XAB X window Analysis and Debugger HeNCE is a X window parallel development tool for PVM. Using HeNCE you can graphically describe the parallelism in your program and HeNCE will automatically add the PVM code for parallelization. HeNCE will make a trace file so you can do a post mortem look at execution. XAB is a X tool which lets you trace individual messages. It has VCR type displays which allow you to control the flow of your program while its running. Your code is instrumented by linking to a special library. A beta test exists for PVM 2.4 and there is no XAB for PVM3.0. When it is available, it will be located on netlib in pvm/xab (ie send index from pvm/xab). Currently, an effort is underway to develop XPVM for PVM3. The funtionality has not yet been determined. The expected released date is by the end of the summer of 1993. To obtain info on HeNCE, send the e-mail message send index from hence to automatic mail server netlib@ornl.gov. For XAB, send the e-mail message send index from pvm/xab Academic reference: [These references are provided here for completeness. Do not ask me for copies; I do not have time to copy them.

New files are: hence1.4.shar shar file (1.8 Mb) hence1.4.shar.z.uu uuencoded compressed shar file (.9 Mb) hence-1.4-changes (short) list of changes porting-status updated porting status read-me.pvm3 notes on HeNCE 1.4 support for pvm3 The major change from HeNCE 1.3 is support for PVM3. In addition, HeNCE should now compile and run on SGI and ALPHA. How to get it: a) from netlib. Send email containing the line send hence1.4.shar.z.uu from hence to netlib@ornl.gov. You will get back several files which you then edit, strip off the headers, and concatenate together to make a uuencode file. uudecode the file and decompress the result, and run that through /bin/sh (in an empty directory) to extract the HeNCE source files. The command "send index from hence" returns a list of everything from HeNCE. b) from xnetlib. Xnetlib is an x-windows program that allows easy file retrival from netlib. You can get xnetlib via anonymous ftp to cs.utk.edu, directory pub/xnetlib, file xnetlib3.3.tar.Z. There are also pre-compiled binaries for several platforms. -- Keith Moore / U.Tenn CS Dept / 107 Ayres Hall / Knoxville TN 37996-1301 Internet: moore@cs.utk.edu BITNET: moore@utkvx Article 110 of comp.parallel.pvm: Path: cnn.nas.nasa.gov!eos!ames!elroy.jpl.nasa.gov!usc!howland.reston.ans.net!darwin.sura.net!emory!cs.utk.edu!cs.utk.edu!moore From: moore@cs.utk.edu (Keith Moore) Newsgroups: comp.parallel.pvm Subject: another way to get HeNCE 1.4 Date: 17 May 1993 22:00:06 GMT Organization: Univ. of Tenn.

To get HeNCE 1.4 via rcp, type: rcp anon@netlib2.cs.utk.edu:hence/hence1.4.shar.z.uu local-file-name (for the uuencoded, compressed version), or rcp anon@netlib2.cs.utk.edu:hence/hence1.4.shar local-file-name (for the uncompressed .shar file). You can also do "ls" commands: rsh netlib2.cs.utk.edu -l anon ls -l hence (on some hosts, the command is "remsh" rather than "rsh") For more information, finger anon@netlib2.cs.utk.edu. Notes: a) This is an experimental service. We will be watching it to see how well it works. You may send comments to moore+netlib@cs.utk.edu. b) Please note: "anon" isn't really anonymous.
