What Concurrent Real-Time does

Concurrent Real-Time, headquartered in Pompano Beach, Florida and operating as a subsidiary of HBK (Hottinger Brüel & Kjær), provides deterministic real-time computing systems, software, and services for mission-critical applications. The company's flagship offering is RedHawk Linux, a proprietary real-time Linux operating system that delivers event response times of less than 5 microseconds on certified platforms via real-time scheduling, kernel preemption, processor shielding, and NUMA optimization. It is complemented by the NightStar development and debugging tool suite, the SIMulation Workbench (SimWB) real-time simulation framework with native integrations to MATLAB/Simulink, VI-grade, SIMPACK, Dymola, Adams, and FMI-based tools, and the FPGA Workbench graphical FPGA programming environment.

The hardware lineup centers on the iHawk multiprocessing platform (Intel/AMD/ARM CPUs up to 224 cores and 8 NVIDIA GPUs), ImaGen visual servers built around Diamond Visionics' GenesisIG engine, SignalHawk PCIe I/O cards, SIGnal Workbench signal conditioning and fault insertion systems, GPU Workbench for deterministic CUDA, and DCIM for data center cabinet management. Bundled solutions include the tiered Missile TestBench HiL platform, while the RedHawk Architect deployment tool and RedHawk KVM-RT hypervisor extend platform manageability and virtualization. As a Preferred Partner with NVIDIA since 2016, Concurrent Real-Time also delivers RedHawk Linux on Jetson embedded edge platforms (Nano, AGX Xavier, AGX Orin) for AI edge workloads.

Revenue is generated through a mix of hardware sales (iHawk systems, SignalHawk cards, FPGA cards), one-time and subscription software licenses (RedHawk, NightStar, SimWB, FPGA Workbench), and professional services including engineering support, consulting, training, and custom integration. Most systems are quote-based with multi-year enterprise contracts, while individual SignalHawk I/O cards are listed between roughly $2,900 and $17,900. Products are sold through a direct enterprise field-sales motion with consultative configuration, supported by content marketing, technical articles, industry events (I/ITSEC, NVIDIA GTC), and a global support network across North America, Europe, and Asia. Aerospace and defense is the primary vertical, with automotive as a co-primary segment and finance, energy, manufacturing, medical, and academia as secondary markets.

Core offering

Concurrent Real-Time sells high-performance real-time computer systems, software, and solutions for mission-critical applications. Its core offering is the RedHawk Linux real-time operating system with sub-5-microsecond event response times, complemented by NightStar Tools for debugging, SIMulation Workbench for HiL/SiL simulation, and purpose-built hardware including iHawk multiprocessing servers, ImaGen visual servers, SignalHawk I/O cards, FPGA Workbench, GPU Workbench, and NVIDIA Jetson real-time Linux support. The platform serves aerospace & defense, automotive, finance, energy, manufacturing, and medical customers requiring deterministic real-time performance.

Product overview

Concurrent Real-Time delivers a modular real-time computing platform combining proprietary real-time operating systems, development tools, and purpose-built hardware for mission-critical simulation, data acquisition, and control applications. The core of the portfolio is RedHawk Linux, a deterministic real-time OS providing sub-5-microsecond response times, paired with the NightStar Tools suite for non-intrusive debugging and performance analysis. The simulation layer is anchored by SIMulation Workbench (SimWB), which manages real-time model execution for HiL/SiL/MiL testing and natively integrates with third-party tools including Simulink, VI-grade, SIMPACK, Dymola, Adams, and CarMaker. FPGA Workbench extends the platform with graphical FPGA programming and a library of pre-built IP cores. The hardware lineup centers on iHawk multiprocessing servers (Intel/AMD/ARM, up to 224 cores, 8 GPUs) and ImaGen visual servers, complemented by SignalHawk I/O cards (analog, digital, FPGA, timing), SIGnal Workbench for signal conditioning and fault insertion, and GPU Workbench for deterministic CUDA computing. RedHawk Architect provides deployment image management, while RedHawk KVM-RT adds real-time virtualization. Specialized solutions include Missile TestBench (tiered HIL bundles for missile development), DCIM for data center cabinet management, and NVIDIA Jetson platform support for embedded AI edge deployments. The architecture is unified around RedHawk Linux as the common OS foundation, with iHawk as the primary compute platform and NightStar/SIMulation Workbench as the common software stack across all solutions.
