DescriptionThe Network Attached Memory (NAM) concept was first introduced in the European project DEEP-ER and provided network accessible volatile storage. The first generation had 2GB of Hybrid Memory Cube (HMC) storage, was used to accelerate the DEEP-ER Checkpoint-Restart protocol and provided shared memory for compute resources.
The NAM will be significantly enhanced in DEEP-EST to support higher memory-capacity, and enable more flexible programmability of NAM processing resources. To provide high capacity (up to multiple TB per NAM) and bandwidth (enabling wire-speed access), different memory technologies will be used, in particular LR-DDR4 DRAM, and NAND Flash as NVMe attached devices.
The NAM exploits the EXTOLL high-performance interconnect technology to access compute nodes. A custom Xilinx Kintex UltraScale+ FPGA design provides the NAM core functionality as well as the interfaces to the DDR4 and NVMe modules.
The talk will introduce the NAM design, describes its internal architecture and its application in the DEEP-EST environment.
