Abstract
A method for job management in an HPC environment includes determining an unallocated subset from a plurality of HPC nodes, with each of the unallocated HPC nodes comprising an integrated fabric. An HPC job is selected from a job queue and executed using at least a portion of the unallocated subset of nodes.

(canceled)
A method comprising:
- determining, using one or more processors, a node of a first job space of a plurality of communicatively coupled nodes has failed, the first job space including a logical grouping of nodes configured to process a job and communicatively coupled to accommodate a logical shape specified by at least one of a job policy and a job parameter;
- determining whether the failed node is allocated to execute the job;
- responsive to a determination that the failed node is allocated to execute the job, identifying operational nodes, other than the failed node, in the first job space;
- terminating a task of the job on each of the operational nodes executing the job;
- deallocating the operational nodes from the job;
- identifying a subset of nodes of the plurality of communicatively coupled nodes, other than the failed node, communicatively coupled in the logical shape;
- allocating the identified subset of nodes to execute the job in a second job space;
- and
- executing the job on the allocated second job space.

A system comprising:
- a plurality of communicatively coupled nodes;
- and
- a management node, comprising at least one processing device, configured to:
- determine, using one or more processors, a node of a first job space of a plurality of communicatively coupled nodes has failed, the first job space including a logical grouping of nodes configured to process a job and communicatively coupled to accommodate a logical shape specified by at least one of a job policy and a job parameter;
- determine whether the failed node is allocated to execute the job;
- responsive to a determination that the failed node is allocated to execute the job, identify operational nodes, other than the failed node, in the first job space;
- terminate a task of the job on each of the operational nodes executing the job;
- deallocate the operational nodes from the job;
- identify a subset of nodes of the plurality of communicatively coupled nodes, other than the failed node, communicatively coupled in the logical shape;
- allocate the identified subset of nodes to execute the job in a second job space;
- and execute the job on the allocated second job space.
