Abstract: A job in a high performance computing system is executed according to a current scheduler configuration. The job is monitored to determine the job's actual resource usage, the job's performance metric and the job's completion. Responsive to determining that the job completed executing, a difference is computed between allocated resources allocated according to the current scheduler configuration at job submission for execution on the high performance computing system and the job's actual resource usage at the job's completion, wherein the difference is computed for each of N number of jobs that complete executing on the high performance computing system, wherein all of the N number of jobs are associated with a given user. Responsive to determining that the difference for said each of N number of jobs meets a criterion, the current scheduler configuration is automatically reconfigured to reduce the allocated resources for the jobs associated with the given user.

Abstract: A computer storage management system includes a memory storing a process; a processor executing the process; and an operating system (OS). The OS includes a filesystem configured to receive a plurality of requests from the process to access data stored on the memory; and a filesystem event handler configured to receive the requests in a sequence determined by an order in which instructions associated with the requests occur within the process, store the sequence of requests without accessing the memory, and execute the sequence of requests.

Abstract: A method of conducting computing experiments, includes executing a set of jobs, performing a comparison of a result of the executed set of jobs with templates of previously-executed experiments which are stored in a knowledge base, and identifying a prunable job of the set of jobs based on the comparison and a user constraint.

Abstract: Resource usage is monitored for a hybrid cloud computing environment having on-premises computing resources and off-premises computing resources, for at least a first time period. For the time period, the amount of the on-premises computing resources and off-premises computing resources are related to the demand for computing services from the environment. Future demand for computing services from the environment is dynamically predicted based on the relating step and a learned function of the demand and/or a projection of future business growth for a business utilizing the on-premises and off-premises computing resources. Based on the predicted future demand, the amount of the on-premises computing resources is dynamically optimized for a future time period, so as to minimize costs for the future time period; and new amounts of on-premises computing resources and off-premises computing resources are provisioned for the future time period, in accordance with the optimizing step.
