rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method for remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
Libporty provides a higher level API for some commonly used library functions such as sockets, date/time, file system access, background processes, and asynchronous DNS resolving. Libporty is configured using scconfig and the API is guaranteed to work the same way on all supported systems. An application that exclusively uses the libporty API will not require autotools/scconfig for porting. Libporty has been tested on Linux, Windows, Mac OS X, multiple BSD variants, Minix, OpenSolaris, and some ancient Unix systems.
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and grids. It is based on a hierarchical design targeted at federations of clusters. Ganglia is currently in use on over 500 clusters around the world and has scaled to handle clusters with 2000 nodes.
PIKT is cross-categorical, multi-purpose software for monitoring and configuring computer systems, administering networks, organizing system security, and much more. PIKT is intended primarily for system monitoring, and secondarily for configuration management, but its versatility and extensibility evoke many other wide-ranging uses. PIKT consists of a sophisticated, feature-rich file preprocessor; an innovative scripting language with unique labor-saving features; a flexible, centrally directed process scheduler; a customizing file installer; a collection of powerful command-line extensions; and other useful tools.
MP-MICH is a Multi-platform uniform MPI implementation, based on MPICH and SCI-MPICH, resulting in a high performance, consistent MPI across both ethernet and SCI networks in a hybrid environment. There is a single, standardized source tree for all platforms. It is compliant with the MPI-1 standard.
Bandwidth Monitor NG is a small console-based live network and disk I/O bandwidth monitor for Linux, BSD, Solaris, Mac OS X, and others. It supports /proc/net/dev, netstat, getifaddr, sysctl, kstat, /proc/diskstats, /proc/partitions, IOKit, devstat, and libstatgrab. An unlimited number of interfaces and disks are supported. Interfaces and disks are added or removed dynamically from the list. You can white or blacklist interfaces and disks. The output includes KB/s, Kb/s, packets, errors, average, max, and total sum, and can be viewed via curses, a plain console, CSV, or HTML. Configuration can be done through a config file or the command line.
bdmn is client/server-oriented backup system. The daemon runs on the machine being backed up, and the client runs on the machine that stores the backup. It is very simple, but very fast. It only uses tar, gzip, uuencode, and Perl, so it is portable to many operating systems. It includes a very simple access control system for itself.
