What is Iperf?
While tools to measure network performance, such as ttcp,
exist, most are very old and have confusing options. Iperf
was developed as a modern alternative for measuring TCP
and UDP bandwidth performance.
Iperf is a tool to measure maximum TCP bandwidth, allowing
the tuning of various parameters and UDP characteristics.
Iperf reports bandwidth, delay jitter, datagram loss.
nuttcp is a network performance measurement tool intended for use
by network and system managers. Its most basic usage is to determine
the raw TCP (or UDP) network layer throughput by transferring memory
buffers from a source system across an interconnecting network to
a destination system, either transferring data for a specified time
interval, or alternatively transferring a specified number of bytes.
nuttcp is based on nttcp, but have several useful features such
as a server mode, rate limiting, multiple parallel streams, and
timer based usage.
The octave-forge package is the result of The GNU Octave Repositry project,
which is intended to be a central location for custom scripts, functions and
extensions for GNU Octave. contains the source for all the functions plus
build and install scripts.
This is benchmark.
The package contains code used to benchmark speed of Octave.
Sipp is a performance test tool / traffic generator for the SIP protocol.
It comes with a few basic SipStone user-agents scenarios (UAC & UAS), i
establishing and releasing multiple calls with the INVITE and BYE methods.
SysBench is a modular, cross-platform and multi-threaded benchmark tool
for evaluating OS parameters that are important for a system running a
database under intensive load.
The idea of this benchmark suite is to quickly get an impression about
system performance without setting up complex database benchmarks or
even without installing a database at all.
Current features allow to test the following system parameters:
* file I/O performance
* scheduler performance
* memory allocation and transfer speed
* POSIX threads implementation performance
* database server performance (OLTP benchmark)
Primarily written for MySQL server benchmarking, SysBench will be
further extended to support multiple database backends, distributed
benchmarks and third-party plug-in modules.
MUMmer is a modular system for the rapid whole genome alignment of finished
or draft sequence. This package provides an efficient suffix tree library,
seed-and-extend alignment, SNP detection, repeat detection, and
visualization tools.
Io_lib is a library of file reading and writing code to provide a
general purpose trace file (and Experiment File) reading interface.
The programmer simply calls the (eg) read_reading to create a "Read"
C structure with the data loaded into memory. It has been compiled
and tested on a variety of Unix systems, MacOS X and MS Windows.
ProtoMol is an object-oriented, component based, framework for molecular
dynamics (MD) simulations. The framework supports the CHARMM 19 and 28a2 force
fields and is able to process PDB, PSF, XYZ and DCD trajectory files. It is
designed for high flexibility, easy extendibility and maintenance, and high
performance demands, including parallelization. The technique of multiple
time-stepping is used to improve long-term efficiency. The use of fast
electrostatic force evaluation algorithms like Ewald, particle Mesh Ewald (PME),
and Multigrid (MG) summation further enhances performance. Longer time steps
are possible using MOLLY, Langevin Molly and Hybrid Monte Carlo, Nose-Hoover,
and Langevin integrators. In addition, ProtoMol has been designed to interact
with VMD, a visualization engine developed by the University of Illinois that is
used for displaying large biomolecular systems in three dimensions. ProtoMol is
freely distributed software, and the source code is available.
PyCogent is a software library for genomic biology. It is a fully integrated
and thoroughly tested framework for: controlling third-party applications;
devising workflows; querying databases; conducting novel probabilistic
analyses of biological sequence evolution; and generating publication quality
graphics. It is distinguished by many unique built-in capabilities (such as
true codon alignment) and the frequent addition of entirely new methods for
the analysis of genomic data.
ADMesh is a program for processing triangulated solid meshes. Currently,
ADMesh only reads the STL file format that is used for rapid prototyping
applications, although it can write STL, VRML, OFF, and DXF files.
Features
* Read and write binary and ASCII STL files
* Check STL files for flaws (i.e. unconnected facets, bad normals)
* Repair facets by connecting nearby facets that are within a given tolerance
* Fill holes in the mesh by adding facets.
* Repair normal directions (i.e. facets should be CCW)
* Repair normal values (i.e. should be perpendicular to facet with length=1)
* Remove degenerate facets (i.e. facets with 2 or more vertices equal)
* Translate in x, y, and z directions
* Rotate about the x, y, and z axes
* Mirror about the xy, yz, and xz planes
* Scale the part by a factor
* Merge 2 STL files into one
* Write an OFF file
* Write a VRML file
* Write a DXF file
* Calculate the volume of a part
