Grid Engine 6.1 will be the next step in the evolution of the Grid Engine software. This release will help administrators to better manage access to computational resources in a cluster and continues to improve its excellent scalability in large clusters with a huge amount of jobs. New functionality delivered with this preview release: * Resource Quotas allow to limit the maximum number of running jobs per user, user group, projects on arbitrary resources like queues, hosts, memory, software licenses. A firewall-like rule syntax allows an unprecedented flexibility in defining Grid Engine Resource Quotas (RQ). The man pages qquota(1), sge_resource_quota(5) and qconf(1) describe the new functionality. The design of the Resource Quotas can be found here: http://gridengine.sunsource.net/source/browse/*checkout*/gridengine/doc/devel/rfe/ResourceQuotaSpecification.html * the Grid Engine Accounting and Reporting Console (ARCo) is now part of the open source project and included with the courtesy binaries. * support for Mac OS X on the x86 platform * support for Linux on Itanium (IA64) * Solaris 10 DTrace monitoring and bottleneck analysis * with the help of our community members job online usage is now supported for Apple Mac OS X, IBM AIX and HP HP-UX * for developers an early access to a Java API (JGDI) to Grid Engine will be provided as a seperate download The courtesy binaries are available at: http://gridengine.sunsource.net/project/gridengine/download_preview.html The corresponding source code tag in the "gridengine" and "arco" project CVS repository has the name V61preview_TAG A snapshot of the sources is available at the Documents & files page: sge-V61preview_TAG-src.tar.gz arco-V61preview_TAG-src.tar.gz
