Distributed computing with Linux and Hadoop

Every day people rely on search engines to find specific content in the many terabytes of data that exist on the Internet, but have you ever wondered how this search is actually performed? One approach is Apache's Hadoop, which is a software framework that enables distributed manipulation of vast amounts of data. One application of Hadoop is parallel indexing of Internet Web pages. Hadoop is an Apache project with support from Yahoo!, Google, IBM, and others. This article introduces the Hadoop framework and shows you why it's one of the most important Linux®-based distributed computing frameworks.

SmoothIT – Incentive-based Models for Peer-to-peer Networks

The largest share of data traffic on the Internet is attributable to peer-to-peer networks which are independent of defined Internet Service Providers. The EU project SmoothIT under the leadership of Burkhard Stiller from the University of Zurich now aims to develop economic incentive schemes with which providers should more efficiently adapt their networks to peer-to-peer use and therefore be able to offer cheaper and simultaneously better services.

Lawrence Livermore erects HPC test bed

One of the biggest challenges for managers of high-production computer systems is testing new code or hardware before it is rolled out across thousands of nodes. Something may work fine on a single server, but it could collapse as it is extended across many more nodes. Compounding the problem is that supercomputer cycles are so in demand these days that getting time on the big iron for testing purposes isn't very likely.

Reconfigurable Computing Prospects on the Rise

With all the recent hoopla about GPU-accelerated HPC, reconfigurable computing with Field Programmable Gate Array (FPGA) has been getting proportionally less attention. While NVIDIA has led the GPU push in HPC, there is no single vendor in the reconfigurable computing space that has jumped into the driver's seat. That hasn't kept a variety of smaller players from trying.

CMU does research on cloud computing

The era of sifting through encyclopedia-sized books for pieces of information is long gone. Since search engines like Google and Yahoo! have become highly popular, vast stores of information are now at everyone’s fingertips. This concept of accessing data stored in different locations from the comfort of one’s home makes up the basis of a field of research known as “cloud computing.” The concept, as simple as it seems, has a plethora of uses, some of which are being explored here at Carnegie Mellon University.
