For an initial study in divisible load scheduling, an optimal computing power allocation problem in a distributedparallelcomputing grid involving two sources and a sink is considered. The objective is to optimally allocate the computing power of the sink in the grid in a such way that the total parallelcomputing finish time of the entire load is equalized to the sequential computing finish time while utilizing the full computing power. A numerical method to calculate the optimal adaptive computing power via a deterministic analysis is presented under several computing constraints. Performance of the computing power adaptation is modeled and evaluated. For performance evaluation, we define average computing finish time.

As high-performance computing (HPC) systems continue to increase in scale, their mean-time to interrupt decreases respectively. The current state of practice for fault tolerance (FT) is checkpoint/restart. However, with increasing error rates, increasing aggregate memory and not proportionally increasing I/O capabilities, it is becoming less efficient. Proactive FT avoids experiencing failures through preventative measures, such as by migrating application parts away from nodes that are "about to fail". This paper presents a proactive FT framework that performs environmental monitoring, event logging, parallel job monitoring and resource monitoring to analyze HPC system reliability and to perform FT through such preventative actions.

This paper proposes Message Flow Simulator (MFS), which evaluates the communication algorithms for inter- connection network of large-scale parallel computer. MFS calculates communication time from the amount of message flow on communication links. To show the characteristics of MFS, we presented the run time of MFS and the estimated virtual communication time on fat-tree networks including up to 3456 nodes for all-to-all communication. We compared MFS with Booksim 2.0 developed at Stanford University, which is an existing flit-level simulator. The ratio of the throughput of the network estimated by MFS differs from that estimated by Booksim (500 flits/packet) by 2.1% on average (3.6% at maximum and 1.2% at minimum). The simulation results of Booksim were close to the results of MFS when a packet consisted of many flits. We conclude that MFS provides the simulation results that reflect characteristics of the communication algorithms.

Many attempts have been made to optimize the median filter from the software and hardware approach. An architectural design of hardware capable of performing real-time median filtering is presented. The architecture uses the histogram approach to calculate the median, while optimizing the sliding window method to reuse all its calculations. Data is output row by row and every input pixel is processed only once. The design is independent of window size or image size, and supports adding more processing elements to support wider images. The control unit design is minimized to enable self-adjustment of plug-and-play processing elements. The architecture is implemented in VHDL and synthesized to a Virtex-2 Pro FPGA. The architecture's performance as well as operation is compared to previous work.

High Performance computing has been very useful to researchers in the Bioinformatics, Medical and related fields. The bioinformatics domain is rich in applications that require extracting useful information from very large and continuously growing sequence of databases. Automated techniques such as DNA sequencers, DNA microarrays & others are continually growing the dataset that is stored in large public databases such as GenBank and Protein DataBank. Most methods used for analyzing genetic/protein data have been found to be extremely computationally intensive, providing motivation for the use of powerful computers or systems with high throughput characteristics. In this paper, we provide a case study for one such bioinformatics application called BLAT running in a high performance computing environment. We use sequences gathered from researchers and parallelize the runs to study the performance characteristics under three different query and data partitioning models. This research highlights the need to carefully develop a parallel model with energy awareness in mind, based on our understanding of the application and then appropriately designing a parallel model that works well for the specific application and domain. We found that the BLAT program is highly parallelizable and a high degree of speedup is achievable. The experiments suggest that the speed up depends on model used for query and database segmentation.
