The Cray XC40 represents a massively parallel multiprocessor supercomputer developed by Cray. It incorporates Intel Haswell Xeon CPUs and offers optional acceleration through either Nvidia Tesla or Intel Xeon Phi devices, all interconnected via Cray’s proprietary "Aries" network. This system is available in configurations cooled by air or liquid. Additionally, the XC series integrates Cray DataWarp technology to accelerate application I/O performance.
