....size ranges from 10 4 to 10 5 integers. Each data point represents the average of 10 runs on a cluster comprised of 2, 4, 6, 8, and 10 heterogeneous processors. the p Gamma 1 splitters requires gp(1 r s ) 2L time. Since each processor is expected to receive approximately c j n keys [Mor98b], Step 6 uses O(c j n) computation time and g Delta maxfr j c j ng communication time, where 0 j p. Once each processor receives their keys, sorting them requires O(c j n lg c j n) time. Thus, the total time of the algorithm is O(c s n lg c s n) g(n p p pr s r s c s n) 5L. The ....

....performance on a wide range of parallel machines. HBSP enhances the applicability of the BSP model by incorporating parameters that reflect the relative speeds of the heterogeneous computing components. Our starting point for the development of algorithms for HBSP are efficient BSP or HCGM [10, 11] applications. Specifically, we develop three HBSP algorithms prefix sums, matrix multiplication, and randomized sample sort that distribute the computational load according to processor speed without sacrificing performance. In fact, the cost model indicates that wall clock performance is ....
....languages runtime systems without a solid theoretical foundation. For an overview of these approaches, we refer the reader to the surveys by Siegel et al. 12] and Weems et al. 20] One notable exception is the the Heterogeneous Coarse Grained Multicomputer (HCGM) model, developed by Morin [10, 11]. HBSP and HCGM are similar in structure and philosophy. The main difference is that HGCM is not intended to be an accurate predictor of execution times whereas HBSP attempts to provide the developer with predictable algorithmic performance. 3 Heterogeneous BSP The Heterogeneous Bulk Synchronous ....

....of the interfaces between layers can result in an efficient design of the solution. 4 Computational Model ParLeda is based on a heterogeneous parallel computational model, named HBSP which is an extension to BSP model. The idea of design and using such model has been originated from [3] that used a similar model (HCGM) based on CGM. HBSP uses heterogeneous processors with different speeds. The speed of processors are considered as model parameters. This speed is a function of all software and hardware parameters like its virtual memory and processor speed involved in processor s ....
