Inventing the AI/HPC Datacenter

PacketFive is an Irish R&D start-up developing novel open-source technologies that shape the future of AI and high-performance computing infrastructure — from academic training programmes to full-stack datacenter simulation.

Our Products The Technology

hicain-vswitchd.c — VDC fabric

static int vswitch_route_frame(struct port *ingress,
                               struct frame *f)
{
    switch (frame_classify(f)) {
    case FRAME_INFINIBAND:
        return ib_forward(ingress, f);

/* RoCEv2 + InfiniBand + L2 multiplexed on one fabric  */

Our Mission

To invent the technologies that will shape the next generation of AI and HPC datacenters — and to make them openly available to researchers, educators and operators worldwide.

Two Pillars of Our R&D

Education that builds the future workforce, and tooling that lets that workforce experiment without a million-dollar lab.

HiCAIN — Academic Courses & Training

High-performance Computing, AI and Networking

HiCAIN is our open-source training programme covering the full AI/HPC software stack — CUDA, ROCm, OFED, OpenMPI, RDMA, RoCE and InfiniBand. Delivered via the HiCAIN Academy learning platform, it equips engineers, students and practitioners with the deep skills modern AI clusters demand.

VDC — Virtual Datacenter Simulation Stack

Software-emulated AI/HPC datacenter

VDC is a 100% software-emulated AI/HPC datacenter — virtual GPUs, virtual NVLink-equivalent fabric, virtual RoCE/InfiniBand TOR switches and PCIe-attached virtual NICs — all running unmodified Linux software. A complete multi-node GPU cluster on a laptop, for learning, research and infrastructure experimentation.
