Estimate Load-dependent Service Demand for Modern CPU

Balancing CPU Load for Irregular MPI Applications

MPI applications typically are designed to be run on a parallel machine with one process per core. If processes exhibit different computational load, either the code must be rewritten for load balancing, with negative side-effects on readability and maintainability, or the one-process-per-core philosophy leads to a low utilization of many processor cores. If several processes are mapped per cor...

CPU Service Classes for Multimedia Applications

We present the design, implementation, and experimental results of our soft real time (SRT) system for multimedia applications in a general purpose UNIX environment. The SRT system supports several service classes for the real time processes based on their processor usage time pattern: periodic constant processing time(PCPT) class, aperiodic constant processing time(ACPT) class, variable proces...

Modeling CPU Demand in Heterogeneous Active Networks

Active-network technology envisions deploying execution environments in network elements so that application-specific processing can be applied to network traffic. To provide safety and efficiency, individual nodes must include mechanisms to manage resource use. This implies nodes must understand resource demands associated with specific traffic. Wellaccepted metrics exist for expressing bandwi...

Ray-Triangle Intersection Algorithm for Modern CPU Architectures

We present an algorithm for determining if a ray intersects a triangle interior; and computing intersection point parameters as well as distance of intersection in response to the ray intersecting a triangle interior. Particularly a variation of a hybrid test having all benefits of Plücker and projected barycentric tests is proposed. The test is also vectorized using SIMD instructions for effic...
