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.”
