128-Core ARM Servers: The Ideal Stage for Split-Kernel
High-core-count ARM platforms offer abundant cores and leading energy efficiency, a natural match for an architecture whose advantages grow with every added core. Multikernel partitions large many-core servers into share-nothing kernel domains, so scalability is guaranteed by the architecture itself.
More Cores, More Advantage
On a traditional single kernel, every core shares one kernel: the more cores, the heavier the global lock contention and cross-core cache-coherence traffic, and scale becomes a liability. Multikernel inverts that curve. Each kernel manages only its own subset of cores, so adding cores adds capacity without adding contention.
Each domain is an independent Linux kernel with dedicated cores. You decide how the machine is partitioned.
Lock Contention Doesn't Grow With Scale
Kernels share nothing: lock contention on 128 cores matches 8, and larger machines require no re-tuning.
Faults and Interference Stay in Their Domain
An overloaded or crashed domain never takes down the machine; everything else keeps running.
Full Value From Every Core
More cores means more independent domains per machine: higher density, higher utilization.
Why ARM, Specifically
The economics that made ARM the fastest-growing server architecture are the same economics that reward split-kernel.
Core Counts Lead the Industry
128 cores and beyond per socket is standard for current ARM server silicon. A single shared kernel turns that abundance into contention; a partitioned machine turns it into independent capacity.
Performance per Watt, and per Dollar
ARM wins deals on performance per watt. Multikernel extends that advantage to total cost of ownership: workloads consolidate at native performance with no hypervisor layer and no virtualization licensing, a TCO case your field teams can take into x86 accounts.
Upstream Linux, Not a Fork
Multikernel is built on upstream Linux with kexec-based kernel spawning and standard hotplug interfaces. Platform enablement is contributed upstream, where the whole ARM ecosystem benefits.
A Three-Step Path to Partnership
We bring the split-kernel stack; you bring the silicon and the platforms. The work is open source end to end.
Platform Adaptation
Joint bring-up on your target machines: kernel boot, device kernel, and driver enablement covering network, storage, and GPU.
Proof of Concept
Validate performance, isolation, and operational gains on your real workloads, side by side with your current virtualization stack.
Upstream & Ecosystem
Push adaptation work into upstream Linux, publish joint results, and build the high-core-count ARM software ecosystem together.
