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)
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)
This paper describes a measurement study of the eeects of thread placement on memory access times on the Kendall Square KSR1 multiprocessor. The KSR1 uses a conventional shared memory programming model in a distributed memory architecture based on a ring of rings of 64-bit superscalar microprocessors. Memory consists of local cache memories attached to each(More)
