On formulating simultaneity for studying parallelism and synchronization

The physical meaning of synchronization and simultaneity in Special Relativity

Based on two previous papers, the physical meaning of synchronization and simultaneity as is presented in Einstein's Special Relativity paper of 1905 is reconsidered. We follow Einstein's argumentation to introduce a criterium of synchronization and for the same arguments we arrive at a different criterium for synchronization. From that we conclude that simultaneity is absolute. Introduction On...

Parallelism, distribution, and synchronization in SR

On the Loss of Parallelism by imposing Synchronization Structure

Recently a new parallel programming model has been presented that imposes synchronization restrictions in order to allow for fully automatic, retargetable program optimization. The motivation for the model is the conjecture that in practice the loss of parallel-ism due to the inherent synchronization restrictions is less than a factor of 2. In this paper we provide compelling evidence in favor ...

Finding Synchronization-Free Parallelism for Non-uniform Loops

A technique, permitting us to find synchronization-free parallelism in non-uniform loops, is presented. It is based on finding affine space partition mappings. The main advantage of this technique is that it allows us to form constraints for finding mappings directly in a linear form while known techniques result in building non-linear constraints which should next be linearized. After finding ...

Putting the Horse Before the Cart: Formulating and exploring methods for studying Cognitive Technology

The First International Conference on Cognitive Technology (CT’95, Hong Kong, 1995) explored a radically new way of thinking about the impact computer technology has on humans, especially on the human mind. Our main aim at that time was a consideration of these effects with respect to rendering the interface between people and computers more humane. And we exemplified our approach by pointing t...
