Free atop software for linux

Atop project is an ASCII full-screen performance monitor, similar to the top command.
At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks and network layers, and it shows for every active process the CPU utilization in system and user mode, the virtual and resident memory growth, priority, username, state, and exit code.
The process level activity is also shown for processes which finished during the last interval, to get a complete overview about the consumers of things such as CPU time.
Atop only shows the active system-resources and processes, and only shows the deviations since the previous interval.
Enhancements:
- A new command, atopsar, has been added to generate detailed system activity reports (similar to the UNIX command sar) using the compressed logfiles as written by atop.
- These reports can also be generated for the current situation by specifying an interval for atopsar on the command line.

TuxWordSmith is a sister application to TuxMathScrabble. It uses XDXF dictionaries to let you play Word Scrabble against the computer.
It currently uses the Oxford English Dictionary and is built atop the EduApp framework. The project also has a screensaver mode where two computer players play endless Scrabble.
Enhancements:
- A new admin GUI and dictionaries in 23 languages.

Hanihani Operation Sanctuary project is an English adaptation of a Japanese visual novel game.
The girl that fell out of the blue.
And the protagonists life, which began to take a turn little by little into the realm of the extraordinary starting from that very day.
- Nao-kun, if you dont get up soon, youre going to be late.
The new school term started today. The protagonists childhood friend, Honami, has kept telling him that hes not a child anymore, and yet continues to come to wake him up. They proceed as they always have to "Hasumidai Academy", which stands atop a hill ... but this time around, as second-year students.
- Naoki, Im going on ahead of you!
And the protagonists cousin, Matsuri, zips past the two of them. After having lost both parents in a terrible accident 5 years ago, the protagonist Naoki Kuzumi was taken in by Matsuris parents. And now, Matsuri herself -- who had been so opposed to Naokis moving in back then -- has become a freshman at Hasumidai Academy.
These ordinary, ordinary days, stretching on forever.
... but then, one day, up on the roof of school ...
Enhancements:
- RTM, all platforms.
- Initial page release. Currently in QC. Expect RTM for all platforms this weekend.

Eagle project is a python library to help GUI development.

Eagle is an abstraction layer atop Graphical Toolkits to make GUI programming as easy as possible. Eagle reaches this by narrowing whats possible to do and providing high level components with easy to use API.

Currently GTK and GTK/Hildon/Maemo are done.

pyglplot is a program to 3D-plot mathematical functions and datafiles. It is written as a module for python and as such features the full power and flexibility of the python programming language.
Main features:
Data Sources
- Plot python functions
- Plot python dictionaries containing the coordinates of the points and their position in the grid
- Plot plain datafiles as understood for example by gnuplot
Graphics
- Can make 3D plots of surfaces in normal or parametric mode
- Support coordinate transforms, i.e. can make e.g. polar plots
- Support for pm3d-style coloring of the surface
- Support for wireframe plotting atop of the surface
- Support for transparency: translucent plots
- Support for different types of fog and arbitrary background colors
- Support for dynamic light and specular reflexes etc.
- Use either perspective projection or parallel projection
- Save the rendered plots as portable network graphics (.png)
- Adjust all graphics parameters via dialog windows
Platforms
- This program is developed and tested on Max OS X 10.4 on powerpc with fink and Debian GNU/Linux on i386. It should compile and run everywhere where its prerequisites and requisites thereof are available. These are gtkglext-1.0 and gthread-2.0. Some minimum versions of the libriaries must be met, unfortunately, the gtk+-2.2 packages provided by fink for Mac OS X 10.3 are not sufficient -- perhaps I will port it there.

Genoa Active Message MAchine is a low-latency, high-throughput driver wrapper for the Linux kernel, using Active Ports (a version of Active Messages).
Genoa Active Message MAchine runs parallel to the IP stack and is designed for LANs only.
Main features:
- A low latency, high throughput communication system for clusters of PCs
- Supports both single and dual CPU processing nodes (Intel IA-32 or x86_64)
- Runs on Gigabit Ethernet
- SPMD parallel processing with message passing
- Can run IP traffic when not in use
- Good programmability thanks to fairly high abstraction level
- Reliable thanks to mechanisms for retransmission of missing packets
- Implemented as a network device driver for Linux 2.6, and released under GNU GPL
Network Of Workstations (NOWs) and clusters of PCs interconnected by modern, industry-standard LAN fabrics (Gigabit Ethernet, Myrinet, SCI) and running the Linux operating system, have became an attractive and cost-effective architecture for parallel and distributed applications. The usual drawback of a standard PC cluster is the poor performance of the support to inter-process communication over the interconnect. Current implementations of industry-standard communication primitives, APIs, and protocols, usually show high communication latencies and low communication throughput.
We have developed a system for inter-process communication, called the Genoa Active Message MAchine (GAMMA). GAMMA runs on Linux clusters of PCs with Intel IA-32 processors (Intel Pentium, AMD K6, and superior models), or x86_64 processors (AMD Athlon64, AMD Opteron, Intel EMT-64), networked by a Gigabit Ethernet.
The core of GAMMA is a custom Linux network device driver, which operates the Network Interface Card (NIC). The GAMMA driver delivers low latency, high throughput communication services based on Active Ports, a mechanism derived from Active Messages. Both point-to-point and broadcast communications are provided. Broadcast communication exploits the Ethernet broadcast directly.
The GAMMA driver is able to manage standard IP traffic as long as no parallel job is running. Therefore, all IP services are up and running whenever the cluster is not in use by any parallel job.
The communication mechanisms implemented in the GAMMA driver are made available to application writers through the GAMMA user library. The GAMMA library provides support to application launch, process grouping, point-to-point/broadcast communications based on the Active Ports mechanisms, and some collective routines (barrier synchronization, and broadcast).
GAMMA provides two levels of QoS. The lower one, corresponding to the fastest communications, is a best-effort service. With this service, network congestion and ``hot spots may cause the receiver NIC or even the LAN switch to loose packets by overrun. The other QoS level provides flow-controlled communication, ensuring reliability up to hardware faults, at a negligible performance penalty.
Installing the GAMMA driver requires only two small and marginal patches to the original Linux kernel. The Linux kernel extended by the GAMMA driver must be installed on each PC in the cluster.
A porting of MPI atop GAMMA is available, called MPI/GAMMA.
