What is the main purpose of local NVMe in a Scratch Filesystem?

The primary function of local NVMe in a Scratch Filesystem is to provide high-speed data access. NVMe (Non-Volatile Memory Express) is a protocol designed to fully utilize the potential of high-speed PCIe storage devices. By employing NVMe for scratch space, the system can dramatically increase read and write speeds compared to traditional storage systems. This speed is particularly beneficial for high-performance computing (HPC) environments where large volumes of data need to be processed rapidly.

In a Scratch Filesystem context, data can be temporarily stored and accessed quickly, allowing for efficient execution of tasks such as simulations or data analysis that require rapid data retrieval and storage. Therefore, the incorporation of local NVMe technology directly aligns with the need for performance enhancements in data-intensive workflows, making high-speed data access the central advantage of this setup.
