HPC computing (High-Performance Computing computing) refers to the use of aggregated computing resources such as CPUs, GPUs, high-speed storage, and low-latency networking to process complex computational workloads at very high speeds. It is commonly used for scientific simulations, artificial intelligence training, and large-scale data modeling. Unlike general-purpose enterprise computing, HPC computing is optimized for extreme parallelism and throughput.

How It Works
HPC systems combine thousands of compute nodes connected by high-speed interconnects such as InfiniBand.
Workloads are divided into parallel tasks and distributed across nodes.
Schedulers allocate resources dynamically to maximize throughput and minimize runtime.
