System and method of providing a fixed time offset based dedicated co-allocation of a common resource set
View Patent ↗Disclosed are a system, method and computer-readable medium relating to managing resources within a compute environment having a group of nodes or computing devices. The method comprises, for each node in the compute environment: traversing a list jobs having a fixed time relationship, wherein for each job in the list, the following steps occur: obtaining a range list of available timeframes for each job, converting each availability timeframe to a start range, shifting the resulting start range in time by a job offset, for a first job, copying the resulting start range into a node range, and for all subsequent jobs, logically AND'ing the start range with the node range. Next, the method comprises logically OR'ing the node range with a global range, generating a list of acceptable resources on which to start and the timeframe at which to start and creating reservations according to the list of acceptable resources for the resources in the group of computing devices and associated job offsets.

C. generating a list of acceptable resources based on the acceptable node range on which to start jobs from the list of jobs to consume resources and a timeframe at which to start the jobs; and
D. creating at least one reservation in the compute environment according to the list of acceptable resources.
