MeSU-alpha is a SGI UV2000 server (SGI presentation), which has the particularity of being a SMP machine. In other words, it differs from a classical cluster architecture in the sense that it can act as a large shared memory system, with a total of 16TB of RAM memory, associated with 1024 cores.
MeSU-alpha is equipped with 64 computes blades, each of which made of 2 motherboards (or nodes), equipped with one Intel Xeon (Sandy Bridge) of 8 cores and with a local memory of 128Gb. The nodes are connected by a Numalink system (version 6) developed by SGI, which allows for the large shared memory.
|Processor||Intel Xeon E5-4650L (Sandy Bridge) 2.6 GHz (2.7 with turbo); 8 cores|
|Memory||16TB DDR3 1600Mhz|
|Interconnection||Numalink 6 12.5 Gb/s|
|Storage||90 TB (Raid 6) : 60x2TB SAS 7krpm|
Front-end / login nodes
2 front-end servers, also called login nodes, allow users to install, compile and launch their jobs on the UV 2000 server.
Each server is equipped with 2 Intel Xeon (Sandy Bridge) with 8 cores, 128 GB of ram memory and 600GB of hard drive storage.
|Processors||Intel Xeon E5-2670 (Sandy Bridge) 2.6 GHz (2.7 with turbo); 8 cores|
|Memory||128GB DDR3 1600 MHz (8 GB/cores)|
|Storage||2×300 GB SAS 15krpm (RAID 1)|
A last server, called the management server, allows the system administrator to manage MeSU-alpha resources and perform maintenance operations.
This server is equipped with 2 Intel Xeon (Sandy Bridge) with 4 cores each, 32 GB of ram memory and 1TB of hard drive storage.
|Processors||Intel Xeon E5-2609 (Sandy Bridge) 2.4 GHz; 4 cores|
|Memory||32GB DDR3 1600 MHz|
|Storage||2×500 GB SAS 15krpm (RAID 1)|
