Wildfire: distributed, Grid-enabled workflow construction and execution

Francis Tang, Ching Lian Chua, Liang-Yoong Ho, Yun Ping Lim, Praveen Issac, Arun Krishnan
2005 BMC Bioinformatics  
We observe two trends in bioinformatics: (i) analyses are increasing in complexity, often requiring several applications to be run as a workflow; and (ii) multiple CPU clusters and Grids are available  ...  The traditional solution to the problem of running workflows across multiple CPUs required programming, often in a scripting language such as perl.  ...  Component eval1 is executed four times in parallel within a parallel for loop.  ...

GridRod

Shahaan Ayyub, David Abramson
2007 Proceedings of the 21st annual international conference on Supercomputing - ICS '07  
Such flexibility allows the pipelining of temporally dependent components, or in contrast, delaying of tightly coupled computations based on the current resource availability and network connectivity.  ...  The scheduler in this case, not only allocates components to distributed Grid resources, but also specifies the inter-component communication mechanism (socket, pipe etc.)  ...  However, when remote communication is performed, a single point of network or CPU failure, which is very common in Grid environments, would require rescheduling of the components.  ...

We refer to this future Grid environment as the "divergent Grid".
