Tyrone Cluster

Introduction :-
	The latest addition to the SERC HPC facility is the 288-cores Tyrone cluster. This cluster is composed of 9 rack mounted nodes, located in the CPU room of SERC. Of the 9-nodes, one is a head node and others are execution nodes. Each node has a total of 32 cores with 64GB RAM. Each core is a 2.4 GHz AMD Opteron 6136 processor, with the node having 4 CPUs of 8-cores each. The cluster nodes are connected using Infiniband HBAs through a Mellanox QDR Interconnect switch. The cluster is managed by the opensource batch scheduler "torque" software for job scheduling and load balancing. The head-node allows user logins for application development and testing. The head node also supports a local scratch filesystem of 1.8 TB, to be used for computational runs. This scratch filesystem is mounted across all execution nodes of the cluster.
Vendor :-
	OEM - Supermicro Authorised Seller - Netweb Technologies, Bangalore, India.
Hardware Overview :-
The cluster has 9 nodes and the hardware configuration for each node is as follows:-
	AMD Opteron 6136, 4 processors (8 cores each) operating at 2.4Ghz clock speed
	64 GB Main Memory DDR3 ECC SDRAM
	500GB SATA HDD 3Gbps for OS and system software
	Infiniband Card MHQH19B-XTR for MPI communication
	Dual-port Gigabit Ethernet Connectivity for enabling logins and NFS.
	The head node alone has two 1TB SATA HDDs (1.8TB of usable space and mounted as local scratch) which is mounted across all the nodes to be used during job execution. Node Interconnect: All nodes of the cluster are connected using their infiniband HBAs through one 24-port Mellanox switch MIS5023Q-IBFR for MPI-communication.
System Softwares/Libraries :-
	Operating System : CentOS 6.0, - Linux x86_64 Platform
