Bug Fixes

• TCP Device: solved bugs that affected performance

csWMPI 1.6 is now based on the csWMPI II product, benefiting from all its performance and usability enhancements as well as supported platforms and tools. Binary compatibility is guaranteed with previous csWMPI 1.5.x versions.

New Platforms

• Operating systems: Supports MS Windows and Linux and heterogeneous computations are allowed.
• 32-bit and 64-bit architectures: Supports Intel 32-bit and 64 bit Extended Systems (AMD64) architectures

New Features

• Easy to use: Easier to configure at runtime and easier to install from a central machine.
• Language Bindings: C, C++ and Fortran language bindings support.
• MPICH compatibility: Compile, link and run applications written for MPICH on csWMPI (Linux only).
• Profiling interface: Profiling interface and VampirTrace compatibility added.
• Easier debugging; csWMPI applications can be debugged with the Distributed Debugging Tool (DDT) from Streamline Computing.

Improved performance

• tcp Device: Enhanced TCP performance with low latency, high bandwith and low CPU Usage. Check special settings for Gigabit Ethernet.
• CPU Usage: Reduced CPU usage in csWMPI while communication is in progress, leaving more cycles free for your application to crunch numbers.
