With the arrival of cloud computing and Big Data, many scientific applications with large amount of data can be abstracted as scientific workflows and running on a cloud environment. Distributing these datasets intelligently can decrease data transfers efficiently during the workflow's execution. In this paper, we proposed a 2- stage data placement strategy. In the initial stage, we cluster the datasets...
The computation of the three-point correlation function (3PCF) is a critical challenge in astrophysics. An algorithm, named as RCSF (recursive convolution for scalar fields), has been proposed to solve 3PCF by using a filter matrix to reduce the computation load. In this paper, we accelerate the 3PCF by parallel implementation of RCSF. The proposed parallel algorithm, denoted as p-RCSF, splits the...
There is a very important class of applications which is named Many-Task Computing (MTC). For a lot of MTC applications, a large number of independent tasks which differ significantly on task complexities will be generated. This brings a great challenge for grids to achieve a high performance for such MTC applications. In this paper, we describe the TCE algorithm, a scheduling algorithm based on Task...
