Announcing QualNet Developer 4.0!
SNT has completed development of a new major release of QualNet. QualNet 4.0 supports state-of-the-art multi-core processors. In order to take advantage of multi-core processors, software applications must execute by means of multiple threads. Today, few software applications are multithreaded, but QualNet is. QualNet Developer 4.0 by default supports dual-core processors, and customers can upgrade to support any multiple of 4 processors.
About Multi-core Processing
What do dual-core, quad-core, and multi-core processors buy you in terms of execution speed? Check out the graph below, which shows how QualNet 4.0 performed on three different multi-core platforms. All dual- and multi-core trials ran faster than real-time.
The simulation was an 802.11b wireless scenario running 700 nodes with terrain-based propagation, random mobility at 30m/s, and AODV routing. The simulation time was 900 s. Traffic through the network consisted of 625 CBR sessions sending 512-byte packets at 1-second intervals. There was no parallel optimization by means of processor partitioning, and with some optimization, additional speedup could be realized.
QualNet executes on shared memory architectures like those described above, and also on distributed architectures such as clusters. Read more on QualNet for multi-core processors and clusters.
Other QualNet 4.0 Improvements
Two other notable additions to QualNet 4.0 include:
New models are:
- the military radios EPLRS and SINCGARS,
- OLSRv2,
- DYMO,
- OSPFv3,
- cellular models,
- pedestrian mobility,
- an SDF Parser,
- CTDB 7 and 8 terrain formats, and
- a new QualNet building format for terrain.
Additional new features include:
- a new QualNet 3D Visualizer for rich QT-based network animation, and
- usability and performance improvements in the 2D Java Graphical User Interface.
