Core Binding

Core and Memory Binding of Jobs in Univa Grid Engine 8.1

Execution nodes in Grid Engine clusters usually have multiple sockets and multiple cores with a hierarchy of different caches. This hardware architecture will provide performance benefit for jobs and therefore improve the overall throughput of a cluster if it is handled correctly.

Univa Grid Engine is not only aware of the underlaying hardware architecture of compute resources. It provides also the necessary semantics to give managers and users of a cluster full control where jobs should be executed and how they should be handled.

Especially Univa Grid Engine 8.1 is extremely powerful. Within this version of Univa Grid Engine the scheduler component is completely responsible for the socket and core selection. Due to that it is possible to guarantee core binding specific requests. This was different in UGE 8.0 and it is still in other available Grid Engine versions.

The scheduler is also aware of the memory allocation capabilities of the underlaying hardware. As result particular memory allocation strategies can be selected so that jobs and underlaying applications will have accelerated access to available memory. Also this feature is new in UGE 8.1.
