Quick summary¶
Last update: March 2016
| LSG cluster | Capacity |
|---|---|
| Operating system | Linux CentOS 6.x 64bit |
| Total number of cores | 128 CPU cores at 2.3 GHz |
| Total amount of memory | 512 GB |
| Total scratch space | 10TB |
| Disk storage | 40TB of staging area |
| Network backbone | 10Gbit/s local switch, 1Gbit/s external connectivity |
Worker Nodes¶
The jobs will be actually executed on this kind of nodes; this is the hardware specification:
- PowerEdge R815 4xAMD Opteron(tm) Processor 6376
- Type: Bulldozer
- Cores: 64
- RAM: 256GB
- Number of nodes: 2
Storage Node¶
This node stores all the data related to the user jobs; every user has a default quota of 50GB, unless a specific one is required:
- PowerEdge R515 2xAMD Opteron(tm) Processor 4280
- Type: Bulldozer
- Cores: 16
- RAM: 128 GB
- Number of nodes: 1
- Storage space: 40TB
Computing Element¶
This is a virtual machine running on one of the Service Nodes; the CE gets the jobs from the users and sends them to the appropriate WNs:
- Cores: 2
- RAM: 4 GB
- Number of nodes: 1
User Interface¶
This is a virtual machine running on one of the Service Nodes; please be aware that this server’s purpose is NOT to execute directly your programs. Use instead Torque commands such us ‘qsub’ to submit your jobs to the Worker Nodes which have more CPU/Memory capacity. Thank you for your understanding. The VM specifications of the UI are:
- Cores: 8
- RAM: 16 GB
- Number of nodes: 1
Service Nodes¶
The hardware specifications of the service nodes:
* PowerEdge R420 2xIntel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz
* Type: Sandy Bridge architecture /w Sandy Bridge-EP cores
* Cores: 24
* RAM: 96 GB
* Number of nodes: 2
