DDN Infinite Memory Engine (IME) based Burst Buffers and file system Cache - a fast data tier between compute nodes and the Lustre file system /scratch - is used as an I/O accelerator for I/O bound problems. This helps avoid overload on the system when a program tries to write large amount of data within a short period of time to the global parallel file system. IME servers consist of Solid State Disk (SSD) that acts as a cache and burst buffer to improve the global file system performance. IME servers are currently available for use in EMMY.
