Abstract: An injection system and method for monitoring and controlling task execution in a distributed computer system. The distributed computing environment is comprised of a plurality of computing nodes for executing an application, wherein the application is divided into tasks that are executed within containers on each of the nodes, and the tasks process vectors comprised of one or more data elements. A control plug-in injected into a specified container for execution with the tasks, wherein the control plug-in profiles footprint information for a targeted vector operated on by the tasks executed within the specified container.

Abstract: A method for estimating job start times on a system may include: performing a first simulation of the system by a first process to generate a first estimate of the start time based a first snapshot of the computing system; and performing a second simulation of the system to generate a second estimate of the start time. The first and second estimates may each be either a distinct time estimate or a range of time estimate, depending on whether the simulations dispatches the job before the respective first and second processes end. The method may then include generating a fifth estimate of the time that the computing job will start by a third process based on estimates respectively generated by the first and second processes.

Abstract: A method for reducing job credentials management load is provided in the illustrative embodiments. A determination is made whether a credential data submitted with a job matches a second credential data stored in a repository, the credential data comprising a set of attributes. Responsive to the credential data matching the second credential data, a reference to the second credential data is associated with the job. The second credential data is updated to enable the job for execution. The job is forwarded with the reference to a receiver application, wherein the reference provides the receiver application an authorization to execute the job.
