Sun Announces Sun Grid Engine 6.2; Transitions Sun Grid Engine 6.1 Scalable Up to 63,000 Cores for Easier Cluster Management August 25, 2008, Volume 126, Issue 4
Sun has released Sun Grid Engine 6.2, the Distributed Resource Management software that provides customers with interoperability capability with an open source project (Grid Engine Open Source) as well as superb, rock solid support for the integrated solution from Sun for all existing hardware and software investments because of binary compatibility for investment protection. Sun Grid Engine leverages all other hardware and operating systems regardless of manufacturers and does not lock them in. Customers will only need one number to call to get answers to any technical challenges they run into. The subscription model saves money and provides support to minimize downtime and lost opportunities. The product has evolved and is installed at some of the top High Performance Computing sites in the world. This release reflects improvements designed to reach a new level of scalability, performance and ease of management.
Among the new features in Sun Grid Engine 6.2 are:
SGE 6.2 Service Domain Manager (SDM) will support and help manage two or more Sun Grid Engine clusters with each grid maintaining its own level of service. In 6.2, the only resources managed by SDM are physical or virtual hosts. Resources are allocated according to Service Level Objectives (SLO) and policies. Hosts are allocated optimally to each grid in the multi-cluster. Hosts can also be allocated manually, bypassing the system. SDM's Reporter component provides detailed monitoring data. The Reporter writes a reporting file with a similar syntax as the reporting file of Grid Engine. In SGE 6.2 the users can request and reserve grid resources in advance, like hosts, memory, licenses, etc. for a specified time window. The scheduler makes sure the resources needed will be in place during the reservation The ability of SGE 6.2 to scale up to 63,000 cores means more efficient communications between qmaster and execution daemons with the scheduler running as a thread in qmaster (faster communication between qmaster and scheduler thread); better resource matching in scheduler; faster qmaster startup; and reduced memory requirements for big clusters
With improved interactive job support users can avoid relying on the use of external commands (rlogin, ssh, telnet) by channeling communications directly through Sun Grid Engine's communication layer.
