Description: Bridges-2 Extreme Memory (EM) nodes provide 4TB of shared memory for genome sequence assembly, graph analytics, statistics, and other applications that need a large amount of memory and for which distributed-memory implementations are not available. Each Bridges-2 EM node consists of 4 Intel Xeon Platinum 8260M “Cascade Lake” CPUs, 4TB of DDR4-2933 RAM, 7.68TB NVMe SSD. They are connected to Bridges-2's other compute nodes and its Ocean parallel filesystem and archive by HDR-200 InfiniBand, providing 200Gbps of bandwidth to read or write data from each EM node.
Recommended Use: Bridges-2 Extreme Memory (EM) nodes enable memory-intensive genome sequence assembly, graph analytics, statistics, in-memory databases, and other applications that need a large amount of memory and for which distributed-memory implementations are not available. This includes memory-intensive applications implemented in languages such as Java, R, and Python. Their x86 CPUs support an extremely broad range of applications, and approximately 42GB of RAM per core provides valuable support for applications where memory capacity is the primary requirement.
