Real-time Linux distro boosts multiprocessor support

"RedHawk Linux 5.4 also improves NUMA performance and provides enhanced Nvidia drivers that support Nvidia's "Cuda" parallel computing technology, says the company.

"Concurrent's RedHawk Linux is aimed at applications with time-critical requirements, such as simulation and training, data acquisition, imaging, financial services, and process control. When run on multiprocessor x86 systems, the distribution is said to offer highly deterministic performance with guaranteed interrupt response times, within a normal, open standards-compliant SMP (symmetric multiprocessing) Linux environment that supports unmodified open source software.

"Based on an enhanced 2.6.31 Linux kernel, version 5.4 is fully compatible with Red Hat Enterprise Linux (RHEL) 5.4, and adds support for new Intel Nehalem and AMD Opteron processors and chipsets, along with PCI Express 2.0 busses, says Concurrent. Version 5.4 is also said to add support for systems with greater than 32 cores, up to a maximum of 48 cores."
