Workflow Global Computing with YML

A Distributed and Parallel Asynchronous Unite and Conquer Method to Solve Large Scale Non-Hermitian Linear Systems

“…Additionally, other hybrid methods can be proposed with different computing components using unite and conquer approach, but it is difficult to implement them without the knowledge of MPI communication. YvetteML (YML) [7] is a workflow language based on user-friendly and hierarchical system-oriented development and execution environment, and XcalableMP (XMP) [14] is a directive-based language extension for distributed memory systems. With YML, the user can automatically allocate the computing units and establish the inter-communication for different tasks.…”

A Matrix Inversion Method with YML/OmniRPC on a Large Scale Platform

“…YML [2] is a framework dedicated to develop and run parallel applications on grids and peer to peer middleware. It is composed of a compiler and a just-in-time scheduler which manages tasks and data dependencies between components [3].…”

“…The figure 2 shows the intra-step and inter-steps parallelism. At each step, the loops (1) and (2) depend on the computation of the inverse block B kk and the loop (3) partially depends on (1) and (2). Then, all matrix products in the loops (1) and (2) are independent tasks and are executed in parallel.…”

“…parallel too, because it can start without the complete end of (1) and (2). At the step 2, the computation of the blocks represented by dark squares is not finished.…”

A Novel Lightweight Authentication Protocol for YML Framework

“…It acts as a well-adapted advanced tool to support designing and executing portable parallel applications over large scale peer to peer and grid middleware [5,6], and its extension version is able to manage at the run-time several middleware backends, achieving a dynamic federation of computing middleware [7]. We also extend the framework to be middleware for cloud computing platform [8,9].…”
