With the progress of research on cluster computing, more and more universities have begun to offer various courses covering cluster computing. A wide variety of content can be taught in these courses. Because of this, a difficulty that arises is the selection of appropriate course material. The selection is complicated by the fact that some content in… (More)
—SIFT is a widely-used algorithm that extracts features from images; using it to extract information from hundreds of terabytes of aerial and satellite photographs requires paral-lelization in order to be feasible. We explore accelerating an existing serial SIFT implementation with OpenMP parallelization and GPU execution.
—Many computational science applications utilize complex workflow patterns that generate an intricately connected set of output files for subsequent analysis. Some types of applications, such as rare event sampling, additionally require guaranteed completion of all subtasks for analysis, and place significant demands on the workflow management and execution… (More)
Kendall Square Research introduced the KSR1 system in 1991. The architecture is based on a ring of rings of 64-bit microprocessora. It is a distributed, shared memory system and is scalable. The memory structure is unique and is the key to understanding the system. Different levels of caching eliminates physical memory addressing and leads to the… (More)
The Buffered Message Interface (BMI) of PVFSv2 is a low level network abstraction that allows PVFSv2 to operate on any protocol that has BMI support. This work presents a new BMI module that supports the VIA over an early release version of InfiniBand and also over Myrinet. The baseline bandwidth and latency of the implementation were compared to the BMI… (More)
—In this paper, we present JUMMP, the Job Uninterrupted Maneuverable MapReduce Platform, an automated scheduling platform that provides a customized Hadoop environment within a batch-scheduled cluster environment. JUMMP enables an interactive pseudo-persistent MapReduce platform within the existing administrative structure of an academic high performance… (More)
This paper describes measurement tests of Parallel Virtual File System (PVFS) and Network File System (NFS) over a commodity Linux cluster connected with Myrinet. PVFS stores a file by storing fixed-size stripes in round-robin fashion across I/O servers. The number and identity of I/O servers is selectable at execution time. Our evaluation includes testing… (More)
