SGI® REACT™

SGI REACT is the only hard real-time performance solution for standard Linux distributions, for which no special custom kernels are required.

SGI has successfully achieved a real-time latency guarantee of 30 µsec for up to 64 threads, which is similar to more specialized hardware-software real- time solutions. With SGI REACT, system administration is easier, since the Linux used on the developer's systems is the same as the production system. The hardware system used as the developer system can also be identical to the production system. And software development is also easier, since the same compilers and tools used in non-real-time applications are also used for real-time programming.

SGI REACT includes the SGI REACT library for Linux hard real-time performance, the SGI Linux Trace debugger for real-time applications, frame rate scheduler, the SGI shield runtime anti-jitter capability, user level interrupt support and the external interrupt driver.
