Welcome to Spectral’s documentation!¶
Spectral is a portable and transparent middleware library to enable use of the node-local burst buffers for accelerated application output on Summit. It is used to transfer files from node-local NVMe back to the parallel GPFS file system without the need of the user to interact during the job execution. Spectral runs on the isolated core of each reserved node, so it does not occupy resources and based on some parameters the user could define which folder to be copied to the GPFS.
