The University of Barcelona supports its 10G network with D-Link switches | News | Connectivity

SIE (European Pc Programs) has put in D-Link Enterprise switcheswithin the computational cluster of the Institute of Theoretical and Computational Chemistry of the University of Barcelona (IQTCUB)

The IQTCUB is one of essentially the most prestigious facilities for analysis in numerous fields of theoretical and computational chemistry. The exercise carried out in it contains the event of computational strategies and instruments, the appliance of numerous methods of digital constructions, supplies science, the research of reactivity and dynamics in chemical reactions, in addition to organic programs and mushy matter. In response to its administrator, Jordi Inglés, they work on the heart greater than 100 researchers of a number of nationalities and earlier than the brand new cluster already had a international computing energy of virtually 4,000 cores and 37TB of RAM.

In 2017, the institute obtained the María de Maeztu award, awarded by the Spanish State Analysis Company, which additionally offered funding funds to develop the technical capabilities aimed toward bettering the middle’s analysis. On this manner, it was determined to extend each the info heart and the computing capability, including on this case a brand new cluster, referred to as IQTC09, which has elevated the quantity of calculation cores by 40% and the RAM reminiscence by 70%. This extra capability has allowed the institute to open analysis to new fields, from molecular dynamics, Synthetic Intelligence, machine studying, design of 3D molecular constructions, in addition to different purposes designed in digital environments for researchers to handle and work together in an setting. 3D with digital actuality glasses.

The cluster is made up of 1,664 cores at 2.9 GHz and 26 TB of RAM reminiscence, deployed in 26 nodes developed by SIE Ladón, accomplice of the D-Link VIP + Channel Program.

SIE is an organization with greater than 30 expertise and specialised in HPC options. It has already put in greater than 20,000 HPC network cores, in addition to 60 computational clusters in private and non-private analysis facilities.

The cluster nodes are based mostly on Gigabyte platforms with AMD Rome processors. These nodes are built-in right into a 10 Gigabit network linked to fiber to the surface for distribution to linked gadgets reminiscent of computer systems and desktop stations and for this they’ve been used D-Link DXS-3400 switches, a household of 10 Gigabit Managed Layer three degree switches designed for high of the rack, campus and knowledge heart environments, in addition to distribution due to its bodily stacking and excessive density of 10 Gigabit ports. Particularly, two models of the DXS-3400-24TC mannequin have been put in within the rack of the brand new computing cluster. In a network scheme as demanding as a computational cluster, it was essential to have top-level switches in phrases of their Degree three switching capability, particularly because of the implementation of routing within the swap itself, thus decreasing bottlenecks that would generate a traditional router designed for the 20/80 mannequin visitors patterns, forcing most of the visitors to cross the subnet boundaries, a system that’s already widespread because of the focus of servers in farms or high-performance cluster programs to which all customers should entry from their respective subnets.

Because of its functionalities of Inter VLAN routing, stacking via VRRP, Lossless Ethernet (DCB) for extremely low latency, Ethernet Ring Safety Switching (ERPS), Change Useful resource Administration (SRM), the D-Link DXS-3400-24TC assured the efficiency mandatory within the exterior entry to the computing cluster. The redundancy It was additionally a key issue, and for this the put in gear has followers and energy provides which are interchangeable in operation (Scorching-Swap), other than having the ability to configure the stacking of models (as much as 4 switches) for redundancy. Relating to their administration interface, they’ve an internet interface and likewise with console port entry for his or her administration via the CLI command commonplace (Full CLI).

In September 2021, a brand new growth was accomplished based mostly on the D-Link DXS 3610-54T / SI swap (a household that involves evolve the DXS-3400 with Open Circulation and SDN, 10 Gigabit ports in copper and fiber, in addition to 40G / 100G QSFP + / QSFP28 ports) and new GPUs. After this replace, it has gone from being a CPU set up to having 17 GPUs with greater than 330 TFlops in easy precision and greater than 178 thousand CUDA cores. As well as, they’re interconnected by an HP ProCurve 5406 2l that enables the opposite members of the college to attach and due to D-Link’s SNMP supervisor software program, D-View 7, it’s doable to have a joint monitoring of the 2 clusters.

It was additionally essential to create a Gigabit network for IPMI and GSM communications. and for this, a D-Link DGS-1210-48, a sensible Gigabit swap with 48 Gigabit ports and full Degree 2 and Degree three Lite administration with static routing has been put in.
