1. A method for managing I/O operations in a shared file system environment, the method comprising:
- receiving, by a plurality of I/O masters executed by a computer processor, from an I/O agent running on each of a plurality of compute nodes organized into a plurality of subsets, information associated with I/O accesses to a shared file system and applications for executing the I/O accesses, wherein each I/O master is responsible for and receives the information from a corresponding subset of the plurality of compute nodes;
creating, by an analytics engine executed by the computer processor, application profiles, based, at least in part, on the received information;
transferring the application profiles from the analytics engine to a job scheduler executed by the one ore more computer processors;
determining, by the job scheduler, application execution priorities for the applications, based, at least in part, on the created application profiles;
determining, by the job scheduler, resource allocations for the application execution priorities based, at least in part, on the created application profiles,wherein the application execution priorities and the resource allocations are used to manage the I/O operations in the shared file system environment.

Abstract
A method for managing I/O operations in a shared file system environment. The method includes receiving for each of a plurality of compute nodes, information associated with I/O accesses to a shared file system, and applications for executing the I/O accesses. The method includes creating application profiles, based, at least in part, on the received information. The method then includes determining execution priorities for the application, based, at least in part, on the created application profiles.
