In this paper we analyze energy usage in divisible load processing. Divisible load theory (DLT) applies to computations which can be divided into parts of arbitrary sizes, and the parts can be independently processed in parallel. The shortest schedule for divisible load processing is determined by the speed of computation and communication. Energy usage for such a time-optimum schedule is analy...

In this short paper, we would like to call professional community’s attention to a daring idea that is surely unhelpful, but is exciting for programmers and anyway conflicts with the trend of energy consumption in computer systems.

Cosmology is undergoing an explosive period of activity, fueled both by new, accurate astrophysical data and by innovative theoretical developments. Cosmological parameters such as the total density of the Universe and the rate of cosmological expansion are being precisely measured for the first time, and a consistent standard picture of the Universe is beginning to emerge. Recent developments ...

Current scanning detection algorithms are based on an underlying assumption that scanning activity can be attributed to a meaningful specific source (i.e. the root cause or scan controller). Sophisticated scanning activity including the use of botnets, idle scanning, and throwaway systems violates this assumption. We propose a class of scanning detection algorithms that focus on what is being s...

• Decision epochs are the beginning of every period. • Action space includes Keep (K), Release & Work (RW), Release & Idle (RI) and Idle (I) for each server. The 16 unique combinations of the two workers’ actions constitute the system’s action space. Action “Keep” requires the worker to continue working on the current job for one more period. Action “Release & Work” requires that the worker sto...
