We work below the application layer — in schedulers, allocators, and the pathways data takes between tenants — because that is where multi-tenant GPU infrastructure is actually breaking.
Modern operating system architectures and traditional Linux kernel subsystems were not originally designed for massive, parallel AI workloads. They were designed for a world of many small, mostly-independent processes competing fairly for a CPU — not a handful of tenants competing for a shared pool of GPUs, each expecting isolation and consistent throughput.
That mismatch shows up in three places. Excessive context-switching burns cycles moving between tenants that all want the accelerator at once. Memory allocators built for general-purpose workloads fragment and stall under the large, bursty allocations parallel AI jobs make. And inter-process communication paths designed for trust between cooperating processes become a liability when the processes on either end belong to different customers.
Individually, each of these costs compute. Together, on shared infrastructure, they also become a security surface — timing side channels, imperfect isolation, and data that lingers somewhere it shouldn't.
We build systems-level software, secure kernel modules, and optimized C/C++ middleware layers to streamline memory access, secure low-level data pathways, and optimize hardware resource utilization for enterprise AI workloads.
Concretely, that means working in the layers most teams don't touch: the code between the scheduler and the device driver, the allocator sitting under a training or inference framework, and the IPC boundary between tenant processes sharing the same physical GPU. It's infrastructure meant to be invisible when it's working — lower overhead and a harder isolation boundary, without asking application teams to change how they write AI workloads.
The rules we build against, in rough order of what we'll trade off first.
Every layer we add has to earn its place on the hot path. If a mechanism can't justify its overhead against the compute it protects or saves, it doesn't ship.
Tenant isolation enforced in the kernel or the middleware is harder to bypass than isolation enforced by convention in application code. We push boundaries down, not up.
Cross-tenant leakage is usually a side effect of something else — a shared allocator, a reused buffer, a scheduling decision — not a missing check. We design the underlying mechanism to make the leak structurally hard, not just monitored.
We don't publish a number we can't reproduce on real hardware under real contention. Until we can, we describe the mechanism, not a benchmark.
Happy to walk through the design with your platform or infra team.
