Experimental Grid infrastructures
The deployment of the Grid'5000 site of Rennes was initiated in November 2003. The major steps for the platforms were
|Date||# Nodes||# Procs||# Cores||Processor type||Node type|
|Dec. 2003||66||132||132||Intel Xeon IA32||Dell PowerEdge 1750|
|Oct. 2004||33||66||66||IBM PowerPC||Apple Xserve G5|
|Nov. 2004||66||132||132||AMD Opteron 248||Sun V20z|
|Dec. 2005||102||204||204||AMD Opteron 246||HP DL145 G2|
|Nov. 2006||66||132||264||Intel Xeon 5148LV||Dell PowerEdge 1950|
|Sep. 2007||33||66||132||Intel Xeon 5148LV||Dell PowerEdge 1950|
|Dec. 2008||65||130||520||Intel Xeon L5420||Digitech Carri Systems CS-5393B|
As of the end of 2008, 196 nodes corresponding to 392 processors and 594 cores are active on our platform. An Additonal 65 nodes, 130 processors, 520 cores are to be installed by the end of the year.
The following interconnection equipments have been acquired since 2003:
|Dec. 2003||2x48||100Mb/s||1 Gb/s||Ethernet||Foundry EdgeIron|
|Dec. 2004||8x24||1 Gb/s||1 Gb/s||Ethernet||Cisco 3750|
|Dec. 2005||66||10 Gb/s||Infiniband||Mellanox/Voltaire|
|Feb 2006||320||1 Gb/s||2x10 Gb/s||Ethernet||Cisco 6509|
|Apr. 2006||33||10 Gb/s||Myrinet||Myricom|
|Sep. 2007||64||10 Gb/s||2x10 Gb/s||Myrinet||Myricom|
As of the end of 2008, the production network interconnects all nodes at 1 Gb/s using Ethernet technology, and provides connectivity to Grid'5000 sites through a 10 Gb/s optical link. A private Ethernet network, the management network interconnecting all nodes, is used for node management: monitoring, reboot, etc. It is exploited by the management software of the platform ( OAR , kadeploy ). Two local high-performance networks are available: an Infiniband network interconnecting 66 nodes at 10 Gb/s and a Myrinet 10G network interconnecting 97 nodes and the main Ethernet interconnect at 10 Gb/s.
The statistics show an average platform usage higher than 75%. The results provided by local users, mainly from the Paris Project-Team, show that experimentations on our platform are cited in 6 PHD thesis, 6 book chapters or journal articles, 30 communications to international conferences and in 11 communications to national conferences.
2008 is a major milestone for this experimental infrastructure as its further development was planned and accepted as ALADDIN-G5K , starting in June 2008. The work in Rennes has started to design an API to access the plateform and the corresponding service oriented architecture based on the REST architectural style.
