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.
