Concurrent, a provider of Linux operating systems, has released a new version of its real-time operating system RedHawk Linux 5.4.
According to Concurrent, the new version includes, enhanced 2.6.31 Linux kernel, full compatibility with Red Hat Enterprise Linux 5 update 4, pre-included CUDA parallel computing SDK support optimised for real-time, new Nvidia graphics driver optimised for real-time performance including use of MSI interrupts and support for Intel and AMD processors and chipsets.
In addition, the new version also supports systems with greater than 32 cores, Linux Performance Counter support for hardware and software events and new Pagemap address viewing utility for Numa platforms.
The company said that RedHawk Linux improves the real-time processes in non-uniform memory architecture platforms such as Intel QuickPath and AMD HyperTransport. It ensures that all pages of a real-time process are local to a given node and that no other process’ pages are using the same node and also has the ability to duplicate libraries and other modules as needed and maintain them simultaneously in multiple nodes.
