“…In the case of MPICH-G2, the initialization and connection aspects are very helpful in building The scattered code about orthogonal concerns in the above figure is separated as aspect code in three different files. We have a few lines of code for rollback recovery since the concern is implemented by reusing the initialization code NAT-enabled MPI implementation, since the proxy [54] for MPICH-G2 is similar to the Message Gateway.…”

In complex software systems, modularity and readability tend to be degraded owing to inseparable interactions between concerns that are distinct features in a program. Such interactions result in tangled code that is hard to develop and maintain. Aspect-Oriented Programming (AOP) is a powerful method for modularizing source code and for decoupling cross-cutting concerns. A decade of growing research on AOP has brought the paradigm into many exciting areas. However, pioneering work on AOP has not flourished enough to enrich the design of distributed systems using the refined AOP paradigm. This article investigates three case studies that cover time-honored issues such as fault-tolerant computing, network heterogeneity, and object replication in the cluster computing community using the AOP paradigm. The aspects that we define here are simple, intuitive, and reusable. Our intensive experiences show that (i) AOP can improve the modularity of cluster computing software by separating the source code into base and instrumented parts, and (ii) AOP helps developers to deploy additional features to legacy cluster computing soft-A preliminary version [1] of this paper was presented at IEEE Cluster 2007,

“…At a given rescheduling event, the job scripts on the active running batch queues synchronize using the global coordinator 2 and simultaneously launch multiple MPI applications, one for each active queue, that coordinate to form a single MPI world. Existing middleware mechanisms including PACX-MPI [9] and MPICH-GX [10] can be used to coordinate the MPI components executed on different batch systems to form a single MPI world. These mechanisms can be used for communications between application components started on different batch systems.…”

Adaptive Executions of Multi-Physics Coupled Applications on Batch Grids

Long running multi-physics coupled parallel applications have gained prominence in recent years. The high computational requirements and long durations of simulations of these applications necessitate the use of multiple systems of a Grid for execution. In this paper, we have built an adaptive middleware framework for execution of long running multi-physics coupled applications across multiple batch systems of a Grid. Our framework, apart from coordinating the executions of the component jobs of an application on different batch systems, also automatically resubmits the jobs multiple times to the batch queues to continue and sustain long running executions. As the set of active batch sysThis work is supported partly by Ministry of Information Technology, India, project ref. no. tems available for execution changes, our framework performs migration and rescheduling of components using a robust rescheduling decision algorithm. We have used our framework for improving the application throughput of a foremost long running multi-component application for climate modeling, the Community Climate System Model (CCSM). Our real multi-site experiments with CCSM indicate that Grid executions can lead to improved application throughput for climate models.
