Vultr ist ein globaler Anbieter von Cloud-Infrastrukturen, der bedarfsgesteuerte virtuelle Maschinen, Bare-Metal-Server, GPU-beschleunigte Instanzen, verwaltete Datenbanken, Objekt- und Blockspeicher, Kubernetes- und Netzwerklösungen anbietet. Die Plattform legt den Schwerpunkt auf KI- und HPC-Workloads mit einer breiten Auswahl an AMD- und NVIDIA-GPUs, schnellen Netzwerken und über 32 Datenzentrumsregionen sowie einem Marktplatz für bereitstellbare Apps und entwicklerfreundliche APIs. Vultr richtet sich an Entwickler und Unternehmen, die nach kostengünstigen, skalierbaren und konformen Alternativen zu Hyperscalern für Cloud-Computing und Speicherlösungen suchen.

Beschreibung

• Architect large-scale GPU clusters within fixed site power budgets that optimizes for maximum GPU density while reserving necessary headroom for compute services, storage, and networking. • Model and validate power consumption across the full cluster bill of materials (GPUs, CPUs, NICs, switches, fabric components, storage, and facility limits). • Evaluate tradeoffs across multiple fabric networking architectures (InfiniBand, RoCE, SpectrumX) as well as multi-plane, 2-tier/3-tier, and rail-optimized topologies. • Determine network scale limits based on switch radix, link speed, topology, and blocking requirements. • Gather, interpret, and maintain detailed SKU-level power and thermal specifications for GPUs, NICs, switches, DPUs, storage, and server platforms. • Develop power-aware cluster configuration templates and capacity-planning models that can scale across sites with varying constraints and allow for quick iteration and ideation. • Document architecture, design choices, tradeoff analyses, and operational considerations for deployment and lifecycle management. • Provide guidance on future-proofing, including the ability to incorporate next-gen GPUs, NICs, or fabrics. • Collaborate with vendors on novel fabric architectures that enable large-scale cluster deployments (100k+ GPUs)

🎯 Anforderungen

• 7+ years designing or building large-scale HPC, AI, or hyperscale GPU clusters. • Expert understanding of GPU and accelerator system design, including node topology, PCIe/NVLink/NVSwitch/ROCm, and NIC-to-GPU affinity considerations. • Strong familiarity with InfiniBand, RoCE, and SpectrumX networking, including multi-tier, multi-plane, Clos/dragonfly variants, and large-radix switch design. • Demonstrated experience modeling power draw and thermal characteristics of servers, GPUs, NICs, switches, optics, and storage systems. • Ability to design networks that maintain full non-blocking performance or intentionally introduce over/under-subscription while understanding impacts on workload performance. • Proven ability to gather and analyze vendor SKU-level specifications and incorporate them into scalable cluster architectures. • Experience balancing customer-driven requirements for compute, storage, and service density in combination with overall GPU count. • Strong documentation, communication, and cross-functional collaboration skills.
