HPC2N - Resources: Hardware page

The newest cluster at HPC2N is named after Abisko National Park, in the Northern Swedish province of Lapland, near the Norwegian border.

The system is comprised of 318 nodes, each with 4 AMD Interlagos 12 core 2.6 GHz processors, for a total of 15264 CPUs.

Number of nodes	Processor	Cores per node	Memory per node	Interconnect	Flops (theo-retical max)
10 'fat'	4 x AMD Opteron processors (6200 Interlagos) 12 core 2.6 GHz)	48	512 GB RAM	Mellanox 4X QSFP 40 Gb/s InfiniBand	158.75 T
308 'thin'		48	128 GB RAM	Mellanox 4X QSFP 40 Gb/s InfiniBand	158.75 T

Each 'fat' node has 1 TB local storage. Each 'thin' node has 500 GB local storage.

The 40 GB/s Infiniband interconnect assures fast inter-node communication.

Akka

The IBM HS21XM HPC cluster at HPC2N is named after Akka, a massif in the southwestern corner of Stora Sjöfallet National Park in northern Sweden.

Number of blades	Processor	Cores per blade	Memory per blade	Interconnect	Flops (theo-retical max)
672 HS21XM	2 Intel Xeon Quad Core L5420 per blade	2 x 4 = 8	16 GB	Cisco Infiniband and Gigabit Ethernet	53.8 T

Akka comprises a total of 672 nodes each equipped with two low power Intel Xeon quad-core L5420 CPUs and 16 GB of RAM for a total of 5376 cores and 10.7 TB RAM. The interconnects are 10 Gbps Cisco Infiniband with full bisectional bandwith and Gigabit Ethernet. Attached to the system is 100 TB of fast disk storage (IBM DS4800). Akka has a theoretical peak performance of 53.8 Teraflops and is reaching 46.04 Teraflops with the HP LINPACK benchmark (85.6% efficiency).

Ritsem

Ritsem is one of the SweGrid machines. It is named after the location Ritsem, near the Stora Sjöfallet National Park in northern Sweden.

On this machine, jobs can only be run over the grid - there is no local PBS job access.

It is comprised of 68 Intel Xeon 2.66 GHz quad-core nodes, each with 16 GB memory per node. The interconnect is GigaBit Ethernet. Ritsem's theoretical max flop rate is 2.89 TF.

Number of nodes	Processor	Cores per node	Memory per node	Interconnect	Flops (theo-retical max)
68	Intel Xeon I5430 (2.66 GHz)	8	16 GB	Gigabit Ethernet	2.89 T

Bender

The tape storage facilities at HPC2N are based on an IBM TS3500 tape library with IBM Ultrium4 tape drives. It currently contains:

- One L53 library manager rack housing tapes, tape drives and control equipment
- Four D53 drive racks housing tapes and tape drives
- A capacity of 2000 tape slots
- Six IBM Ultrium 4 tape drives capable of storing 800GB uncompressed data per tape at the transfer speed of 120MB/s
