CD-HIT Workflow Execution on Grids Using Replication Heuristics

J. L. V, E. Huedo, R. S. Montero, I. M. Llorente
2008 2008 Eighth IEEE International Symposium on Cluster Computing and the Grid (CCGRID)  
In this work, we analyze their use for workflow scheduling on Grid infrastructures.  ...  Different heuristics such as list scheduling, agglomeration and replication are available for optimizing workflow execution.  ...  Nevertheless, execution times measured on the Grid were higher than those obtained locally as Grid environment is highly dynamic, heterogeneous and faulty.  ...

2013 Proceedings of the 27th international ACM conference on International conference on supercomputing - ICS '13  
The techniques in our framework include dynamic scheduling of work on CPU and GPU cores, maximizing reuse of data present in GPU memory, data management in GPU memory, and combining multiple kernels.  ...  The effective use of GPUs for accelerating applications depends on a number of factors including effective asynchronous use of heterogeneous resources, reducing memory transfer between CPU and GPU, increasing  ...  The G-Charm runtime then schedules these objects for GPU execution. Thus the G-Charm runtime performs work agglomeration dynamically by combining kernels of multiple work requests for GPU execution.  ...
