In this paper, the concept of a new 5-axis hybrid machine tool is proposed. The machine is a tool being with both parallel and serial structures, which is based on a novel 2-DOF parallel platform and serial orientations. The machine tool has advantages in terms of high stiffness, high dexterity, high speed, and being capable of long components manufacturing. The kinematics characteristics, such...

Profess is a parallel program simulation tool designed to help application programmers in evaluating the performance of candidate implementations of their programs on a parallel machine. Users provide a high-level description of each program as structured compositions of known programming skeletons and program components. The system then uses a mixture of performance models and actual runs on t...

Parallel compilers need detail architectural knowledge about the target machines to optimize user programs. The knowledge is needed in order to realize the potential parallelism provided by the hardware and to match the program parallelism with the machine parallelism. In most parallel compilers, the architectural infonnation of the target machine are blurred into the control structures of the ...
