Abstract: Methods and systems are provided for improving user authentication and access control by a network file system service in a multi-tenant public cloud environment by receiving a request for a connection to a file system from a file system client (client), sending an identification request for identification authentication of the client to a control system, receiving a response from the control system, establishing the connection to the file system upon determining that the connection to the file system is allowed based on cloud tenant information associated with the client, receiving an attempt to access the file system from the client by a sub-user, authenticating the sub-user based on the cloud tenant information, issuing a security token including a globally unique sub-user identifier of the sub-user, and using the security token to determine access rights of the sub-user to the file system for a subsequent request.

Abstract: A method, computer program product, and system for providing provenance tracking in a workflow system. The computer-implemented process provides for one or more processors to receive a workflow definition input. One or more processors perform workflow job commands, in response to receiving a workflow definition, and a workflow instance request. One or more processors access an input file associated with the workflow instance. One or more processors generate, at run-time, provenance metadata. One or more processors generate, at run-time, a global file identification (ID) associated with an output file. One or more processors link the global file ID and the provenance metadata to the output file of the workflow instance, and one or more processors store the output file, which includes the global file ID and the provenance metadata, both linked to the output file.

Abstract: For workflow test, a processor executes a workflow instance. The workflow instance includes a first workflow description of step names for a plurality of jobs. The processor further receives a modification to the first workflow description as the workflow instance executes. In addition, the processor synchronizes the modified workflow description to the executing workflow instance as the workflow instance executes. A workflow context of the executing workflow instance is preserved.

Abstract: As disclosed herein a method, executed by a computer, for automatically determining a workflow completion state includes initiating a workflow including one or more jobs, receiving a notification that a first job corresponding to the workflow has finished, checking dependency requirements of a successor job corresponding to the first job, submitting the successor job for processing if the dependency requirements have been satisfied, and evaluating a completion status of each of the one or more jobs to determine whether the workflow is still running. Complex workflows may consist of many jobs, all of which may not be required to complete for the workflow to complete successfully. The method described herein enables the completion state of a workflow to be determined without requiring user defined completion criteria.

Abstract: Work flows consist of the following steps: (i) receiving a work flow data set that defines a work flow which includes a plurality of work items; and (ii) defining, a centralized and pattern-based work flow level job input/output (I/O) characteristic set that includes at least I/O settings for work items included in the work flow.
