This instance type is an InfiniBand-enabled variant of the standard High Core AMD Genoa CPU instance, based on the same AMD Genoa 9654 platform with a very high vCPU count and large RAM capacity. It is intended for HPC and tightly coupled multi-node workloads that require strong multi-threaded CPU performance and access to an InfiniBand fabric for low-latency, high-throughput inter-node communication (for example, MPI-based simulations or CPU-heavy components of hybrid GPU/CPU HPC pipelines).
Specifications
1 vCPUs are logical CPU threads, not physical cores; in most CoreWeave CPU instances, vCPU count is typically 2× the physical core count due to SMT/hyper-threading.2 Usable storage is less than the raw capacity when configured as RAID. See RAID layout and throughput to learn about RAID configurations and their performance characteristics. Primary use cases
HPC workloads that need good multi-threaded CPU performance and large memory capacity, and access to an InfiniBand-based fabric for tightly coupled, latency-sensitive communication across Nodes. Last modified on April 20, 2026
