Neptune has 2 Racks with 80 computing nodes and a speed of 30 Teraflops. The model of nodes that form Neptune are: IBM iDataPlex dx360 M4, the same one that had the Marenostrum III.
Each node has 2 Intel Xeon E5-2670 Sandy Bridge CPUs, operating at 2.6 GHz, providing 16 cores per node. The physical memory per node is 64 GB. This gives us a capacity of 1280 cores and 5 TB of RAM.
The interconnection between nodes, has an Infiniband FDR10 network ensuring high speed communication between the nodes and the storage infrastructure is deployed on a distributed storage with IBM GPFS technology with a total of 130 TB of available space.
The main technologies we use to manage the cluster are the following:
- CentOS operating system.
- Slurm as task planner and resource management.
- Easybuild and Lmod to deploy and use software.
