LASC is a heterogeneous Beowulf-like Linux cluster, which consists of 2 file-server nodes (VECTOR and DELL) and 82 computational nodes:

DELL: Dell PowerEdge T420 (1x Quad-Core Intel XEON E5-2407v2 2.40GHz, 32GB RAM, 500GB SATA HDD & 12TB SATA (7200 rpm) HDD & 8 x 12TB SATA (7200 rpm) HDD),

VECTOR: SuperMicro SuperServer (1x Dual-Core Intel XEON E3110 3.00GHz, 4GB RAM, 80GB SATA HDD & 8 x 1TB SATA (7200 rpm) HDD),


LASC1: SuperMicro SuperServer 6015B-TV servers (2x Quad-Core Intel XEON E5320 1.86GHz, 16GB RAM, 240GB SATA SSD & 1TB SATA (7200 rpm) HDD & 2 x 1.5TB SATA (7200 rpm) HDD, 60 GFlops),

LASC50-64: SuperMicro SuperServer (2x Six-Core Intel XEON E5-2640 2.50GHz, 64GB RAM, 240GB & 240GB SSD, 240 GFlops),

LASC70-89: Dell PowerEdge R420 (2x Eight-Core Intel XEON E5-2450v2 2.50GHz, 128GB RAM, 300GB & 300GB SAS (10000 rpm) HDD, 320 GFlops).

LASC100-123: Dell EMC C6400 2U Servers (2x 20-Core Intel XEON Gold 6148 2.40GHz, 192GB RAM, 3 x 480GB SATA SSD, 3072 GFlops).

LASC124-147: Supermicro SYS-6029TP-HTR 2U Servers (2x 20-Core Intel XEON Gold 6148 2.40GHz, 192GB RAM, 3 x 480GB SATA SSD, 3072 GFlops).


The cluster is connected to the Internet through the Firewall. Each node has two Network Interface Cards (NICs), supporting the Gigabit (1000 Mbps) Ethernet connections.

The nodes are interconnected by two local area networks (LANs). The first LAN is managed by 2x HP 1810-48G and 2x HPE 1820-48G switches and is used for file exchange and communication purposes. The second LAN is managed by 2x Cisco SG300-28PP and 2x HPE 1820-48G switches and is dedicated to data exchange during parallel computations.

The total resources available to users are 2376 CPU cores, having the theoretical peak performance of about 157 TFlops, 12 TB RAM memory, and 127 TB total hard disk space.
