I need a high-core-count dedicated server for a short-term workload—ideally either two 64-core CPUs or one 128-core CPU. Most dedicated-server providers I've found require at least a one-month commitment, and I haven't located suitable hardware with hourly or daily billing. Are there providers that offer this level of compute for only a few days? A cloud instance is acceptable if it provides comparable CPU performance and access to local NVMe storage.

An AWS C6a 32xlarge provides 128 AMD vCPUs and 256 GB of RAM. It’s roughly $4.90 per hour, so two days would cost around $235 before storage, data transfer, and other charges. For a CPU-heavy job with a deadline, that may be easier than trying to find a bare-metal rental.
Cloud providers are probably the most practical option for this. AWS, Azure, and similar services bill by the second or hour and offer instances with well over 100 vCPUs. They won’t be physically dedicated in the traditional sense, but they can provide the short-term compute capacity you need.
If you only need raw compute rather than a full enterprise cloud stack, also compare lower-cost providers such as DigitalOcean, Akamai Connected Cloud, or RunPod. Availability varies, but they can be more economical for short jobs.
Most traditional dedicated-server companies require a monthly rental because provisioning and reclaiming physical machines is more involved. Hetzner and other dedicated-server providers are worth checking, but hourly or daily availability for 128 cores may be limited.
Before choosing the hardware, check whether the workload can be split across several smaller machines. If it can, multiple instances may be easier to obtain and could cost less than one very large server. If the software requires shared memory across all cores, then a large cloud instance or specialized bare-metal rental is the better fit.
