(It's difficult to destill the important changes from that file, which
is why I'm not pasting the entire collection in here.)
NetBSD-current, the way mpi-ch test for them and implements them
(using the #pragma weak directive) is currently broken.

OpenPBS is a generic network queuing system.
The Portable Batch System (PBS) is a flexible batch queueing and
workload management system originally developed for NASA. It operates
on networked, multi-platform UNIX environments, including
heterogeneous clusters of workstations, supercomputers, and massively
parallel systems. Development of PBS is provided by Altair Grid
Technologies.
of distributed systems:
GridSim is a toolkit for modeling and simulation of parallel and distributed
systems such as Clusters and Grids. GridSim is part of the Gridbus Project
(http://www.gridbus.org/).
The GridSim Toolkit includes:
* GridBroker:
It is Grid scheduler built on top of GridSim for application
scheduling on Grid based on Deadline and Budget Constrained
Scheduling Algorithms.
* GridSim:
It is built on top of SimJava. SimJava is a process based discrete
event simulation package for Java with animation facilities.
* Visual Modeler:
It enables the user to create experiments on different Grid testbeds
and generate the default Grid Broker source codes (in Java).
The Distributed Queueing System is designed as a management tool to
aid in computational resource distribution across a network. DQS
provides architecture transparency for both users and administration
across a heterogeneous environment, allowing for seamless interaction
for multiple architectures. Highly mutable custom site configurations
are possible under DQS. This abilty to customize DQS leads to
effective resource distribution and increased network throughput.
From the packages README:
Version 1.2.5 is primarily a bug-fix release. New features include
Significantly better collective algorithms are available.
Major changes for the globus2 device and the ch_nt device.
Information on previous versions
--------------------------------
Features new or improved in Version 1.2.4 included:
SMP support has been inproved through the use of sched_yield. SMP Systems that
are not oversubscribed can consider configuring with --disable-yeild.
A number of bugs in the ch_p4, ch_p4mpd, and ch_shmem device hae been fixed.
These could cause programs to hang or generate error messages.
Features new or improved in Version 1.2.3 included:
Bug fixes and improved-portability,
particularly in the area of Linux and Mac OS X support. Other new features
include better support for Intel compilers, particularly for IA64 Linux,
better support for various Fortran compilers, and some fixes for rare race
conditions in the ch_p4 device. The documentation on the ch_p4mpd device and
the MPD system has been improved. Version 1.2.3 also includes all of the
source for both the Unix and Windows versions. Windows users should still
use the self-installing version available through the web page. The globus
device now supports version 2 of Globus.
Features new or improved in Version 1.2.2 included:
There are a number of improvements to the ch_p4 device that improve both
performance and reliability, particularly on Linux platforms.
Significant upgrades have been made to the MPD system of daemons that provide
fast startup of MPICH jobs, management of stdio, and a crude parallel debugger
based on gdb.
linda is an simple library implementation of Linda parallel
programming system (http://www.cs.yale.edu/Linda/linda.html). To
write a parallel program with linda, you have to know only 6
functions: spawn, out, in, inp, rd and rdp with linda.
the scripts/ directory, it will be run automatically as part of
the build process, by bsd.pkg.mk. There are now exactly 5 packages
in pkgsrc which use this facility, and yet, for every package build,
the existence of a script is checked by bsd.pkg.mk once before the
target is executed, and once afterwards. This incurs needless
overhead.
Move the separate pre- and post- script handling out of bsd.pkg.mk into
the individual package Makefiles, where it's much more obvious what is
happening, anyway.
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
Changes include:
Added new dvt command, which allows you to open xterms to multiple hosts
and control them all via one input window.
Added new jsh command, which allows better job scheduling specifically
designed for parallel compiling.
Multiple bugfixes and enhancements. Much much faster execution.
says to use type time_t for ctime(3).
- Fix some format strings for 64 bit systems.
- use '?=' instead of '='when setting the command used for rsh/ssh so the
user can set it in mk.conf (PVM_SSH).
you can do something like:
make CC="gcc -pipe" PKG_FC="f77 -pipe" CFLAGS="-Wformat -g" FFLAGS="-g"
and still have pvm compile correctly.
Addresses PR pkg/12949 submitted by Thor Simon <tls@cs.stevens-tech.edu>.
Add PLIST.java (contains additional installed files if a javac is
present during build).
Modify Makefile to take the possible presence of a Java compiler
into account.
Convert most MESSAGE files to new syntax (${VARIABLE} gets replaced,
not @VARIABLE@, nor @@VARIABLE@@).
By default, substitutions are done for LOCALBASE, PKGNAME, PREFIX,
X11BASE, X11PREFIX; additional patterns can be added via MESSAGE_SUBST.
Clean up some packages while I'm there; add RCS tags to most MESSAGEs.
Remove some uninteresting MESSAGEs.
out of date - it was based on a.out OBJECT_FMT, and added entries in the
generated PLISTs to reflect the symlinks that ELF packages uses. It also
tried to be clever, and removed and recreated any symbolic links that were
created, which has resulted in some fun, especially with packages which
use dlopen(3) to load modules. Some recent changes to our ld.so to bring
it more into line with other Operating Systems also exposed some cracks.
+ Modify bsd.pkg.mk and its shared object handling, so that PLISTs now contain
the ELF symlinks.
+ Don't mess about with file system entries when handling shared objects in
bsd.pkg.mk, since it's likely that libtool and the BSD *.mk processing will
have got it right, and have a much better idea than we do.
+ Modify PLISTs to contain "ELF symlinks"
+ On a.out platforms, delete any "ELF symlinks" from the generated PLISTs
+ On ELF platforms, no extra processing needs to be done in bsd.pkg.mk
+ Modify print-PLIST target in bsd.pkg.mk to add dummy symlink entries on
a.out platforms
+ Update the documentation in Packages.txt
With many thanks to Thomas Klausner for keeping me honest with this.
of the individual source files making a summary difficult. Of note though is
they have incorporated quite a number of the patches from our 3.4.2 package
hence the removal of 22 (!) patches.
-Add USE_FORTRAN to the package Makefile for correct handling of the
required fortran compiler.
-Fix the .m4 files which control how fortran symbols are handled.
-Rework package to use a different PVM_ARCH for each MACHINE_ARCH. As
opposed to a single PVM_ARCH. This addresses PR pkg/6890 (Thanks to
Ignatios Souvatzis for the PR).
-Rework package to install missing programs including: pvmgetarch, aimk
debugger, debugger2, and the configuration stubs (*.def, *.m4). This
address part of PR pkg/6924 (Thanks to Ignatios Souvatzis for the PR).
-Rework package to maintain the normal pvm3 directory layout so that only
one variable (PVM_ROOT) has to be set to a non-traditional value. This
address the remainder of PR pkg/6924 (Thanks again Ig!).
Fixes a few bugs, makes it more portable to
other operating systems, gives about 20% speedup in command processing,
adds SIGINT processing to give up on the current node, formats output
much nicer, makes pdf work on more operating systems, and other
fine enhancements.
