HFTKernel — Predictable Linux for Latency-Critical Trading

Trading infrastructure

Four production problems HFTKernel solves for trading systems

HFTKernel removes operating-system variability from the path between market data, strategy, risk, execution, and the NIC.

Clean trading cores

Keep trading cores free from operating-system noise

Move IRQ, softIRQ, RCU callbacks, timers and background work away from latency-critical CPUs so market data, strategy, risk and execution loops run on clean cores.

Shorter latency tails

Reduce tail latency across the trading path

Shorten rare p99.9, p99.99 and p99.999 pauses that make quotes stale, weaken queue position and delay order transmission even when average latency looks acceptable.

Predictable memory

Make memory behavior predictable under load

Control reclaim, compaction, transparent huge pages, NUMA balancing and allocator behavior to protect the active working set from multi-microsecond memory stalls.

Stable network and time

Stabilize network processing and time synchronization

Align NIC queues, interrupt affinity, packet processing, PTP/PHC and timestamping so the path from market data to the wire stays measurable and repeatable.

Production architecture

One verified workflow from source to measured deployment

HFTKernel connects stable Linux source, latency-focused configuration, native package generation, immutable delivery, and repeatable CPU and memory measurement.

Verified stable Linux baseline

Each production generation starts from an exact upstream stable Linux release, verifies the source archive and records the complete build identity.

Cloud and bare-metal profiles

Cloud packages target AWS EC2, ENA and PTP/PHC workflows. Hardware packages target physical NICs, NUMA, storage and colocation systems.

Latency-oriented CPU execution

The profile combines 1000 Hz timers, preemption, NO_HZ_FULL, isolated CPUs and RCU callback offload for clean trading-core execution.

Controlled memory behavior

MGLRU, low-swap runtime policy and the HFT allocator-tail profile keep active application memory responsive under sustained load.

Network performance profile

The build includes high-resolution timers, production network policy, BBR/fq support and platform-specific driver packaging.

Current production toolchain

Build generations use the current official GCC production release with O3 optimization and a reproducible, recorded toolchain identity.

Native OS packages

Every target receives native DEB, RPM, or TGZ packages built inside its own operating-system environment.

Integrated measurement bundle

Every platform and OS bundle includes cpujitter and memjitter packages for repeatable CPU and memory latency measurement.

Release-specific support packages

Matching kernel tools, headers and platform packages are delivered for the exact HFTKernel release.

Immutable release delivery

Signed links are pinned to a verified immutable release with SHA-256 metadata and controlled private delivery.

Production deployment assets

Package metadata and runtime payloads support repeatable GRUB, initramfs, CPU isolation, IRQ and memory-policy deployment.

Custom engineering

Firm-specific profiles can target a defined CPU, workload, NIC, cloud instance, bare-metal platform and operating model.

FAQ

Production, packaging and measurement

What is HFTKernel?

HFTKernel is a production Linux kernel package set for latency-sensitive trading, market-data, execution, risk and research systems. It combines a verified stable Linux baseline with CPU isolation, memory, timing and network profiles designed for predictable execution.

What is included in each download bundle?

Each operating-system and platform bundle includes the HFTKernel native package set plus cpujitter and memjitter. Matching kernel tools, headers and platform packages are included where applicable.

Which operating systems are supported?

The production catalogue supports native packages for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 26.04 LTS, Debian 11, Debian 12, Debian 13, RHEL 8-compatible, RHEL 9-compatible, RHEL 10-compatible, AlmaLinux 8, AlmaLinux 9, AlmaLinux 10, Rocky Linux 8, Rocky Linux 9, Rocky Linux 10, CentOS Stream 9, CentOS Stream 10, Fedora Linux 44, Arch Linux base-devel, NixOS-compatible base.

How is the package format selected?

Select the operating system in the request form. HFTKernel automatically provides the native package format for that target: DEB for Ubuntu and Debian, RPM for Enterprise Linux and Fedora targets, or TGZ for Arch Linux and the NixOS-compatible base.

What is the difference between Cloud and Hardware packages?

Cloud packages target AWS EC2 deployment with ENA and PTP/PHC workflows. Hardware packages target bare-metal and colocation systems with physical NIC, NUMA and storage requirements.

What does cpujitter measure?

cpujitter measures scheduling and execution gaps on a pinned CPU, reports high-percentile and maximum latency, and records IRQ and softIRQ activity around the measurement core.

What does memjitter measure?

memjitter measures memory-allocation and first-touch latency under controlled working-set and memory-pressure phases. It reports allocator-tail percentiles, maximum latency and throughput.

What measurement results has HFTKernel produced?

Controlled cpujitter measurements recorded 94.02% lower p99.999 CPU jitter and 99.17% fewer gaps above 5 microseconds. Controlled memjitter measurements recorded 95.4% lower p99.999 first-touch latency while preserving throughput.

How are HFTKernel releases named?

Public release names are sequential within each kernel version. A new kernel version starts at r1, followed by r2, r3, and later revisions. Content hashes remain in SHA-256 integrity metadata and never appear in the public release name.

How are HFTKernel releases built?

The build resolves an exact upstream stable Linux release, verifies it, compiles one immutable payload per platform and creates native packages in each target operating-system environment. Build identity and checksums are retained with every release.

How do signed download links work?

After a package-access request, HFTKernel sends a 24-hour signed link for the selected platform and operating system. The link remains pinned to the exact immutable release listed on the download page.

Can HFTKernel be customized for a specific workload?

Yes. Custom builds can align the kernel, compiler, CPU target, isolation layout, IRQ topology, memory policy, NIC configuration and measurement plan with a specific workload and deployment environment.

What is included in the free technical consultation?

The consultation reviews the workload, current platform, operating system, latency objectives, CPU and NIC layout, measurement approach and the scope of a production or custom HFTKernel deployment.

What does commercial access cover?

Commercial access covers official builds, validation, private delivery, updates, deployment support, measurement support and custom engineering. Linux kernel components remain available under their applicable open-source licenses.
