The Tera Multithrcadcd Architecture (MTA) is a new parallel supcrcomputer currently being installed at San Diego Supercomputing Center (SDSC). This machine has an architecture quite different from contemporary parallel machines. The computational processor is a custom design and the machine uses hardware to support very fine grained multithreading. The main memory is shared, hardware randomized...

It is straightforward to derive well-known higher-order flow analyses as abstract interpretations of well-known abstract machines. In this paper, we explore multi-core parallel evaluation of one such abstract abstract machine, the CES machine. The CES machine is a variant of CESK machines that runs Continuation Passing Style (CPS) λ-calculus. Using k-CFA, the concrete semantics for a CES machin...

We have designed and implemented a virtual machine monitor that virtualizes a sharedmemory multi-processor machine on a commodity cluster. This functionality greatly simplifies utilization of commodity clusters. For example, it enables parallel applications for sharedmemory multi-processor systems to run on clusters without any change of the applications. Moreover, commodity operating systems t...

Closed-form solutions were developed to optimize kinematics design of a 2-degree-of-freedom (2DOF) planar parallel manipulator. The optimum design based on the workspace was presented. Meanwhile, a global, comprehensive conditioning index was introduced to evaluate the kinematic designs. The optimal parallel manipulator is incorporated into a 5-DOF hybrid machine tool which includes a 2-DOF rot...

Automatically building a large bilingual corpus that contains millions of words is always a challenging task. In particular in case of low-resource languages, it is difficult to find an existing parallel corpus which is large enough for building a real statistical machine translation. However, comparable non-parallel corpora are richly available in the Internet environment, such as in Wikipedia...

We ported the computer algebra system Maple V to the Intel Paragon, a massively parallel, distributed memory machine. In order to take advantage of the parallel architecture, we extended the Maple kernel with a set of message passing primitives based on the Paragon's native message passing library. Using these primitives, we implemented a parallel version of Karatsuba multiplication for univari...

Given a sequence Q of n numbers positive and negative the maximum subsequence of Q is the contiguous subsequence that has the maximum sum among all contiguous subsequences of Q Given a two dimensional array A of n n numbers positive and negative the maximum subarray of A is the contiguous subarray that has the maximum sum among all contiguous subarrays of A We present two O log n time parallel ...
