Employing Software-Managed Caches in OpenACC: Opportunities and Benefits
Ahmad Lashgar, Amirali Baniasadi
Article No.: 2
The OpenACC programming model has been developed to simplify accelerator programming and improve development productivity. In this article, we investigate the main limitations faced by OpenACC in harnessing all capabilities of GPU-like...
Validating the Simulation of Large-Scale Parallel Applications Using Statistical Characteristics
Deli Zhang, Jeremiah Wilke, Gilbert Hendry, Damian Dechev
Article No.: 3
Simulation is a widely adopted method to analyze and predict the performance of large-scale parallel applications. Validating the hardware model is highly important for complex simulations with a large number of parameters. Common practice...
Dealing with Dead Ends: Efficient Routing in Darknets
Stefanie Roos, Thorsten Strufe
Article No.: 4
Darknets, membership-concealing peer-to-peer networks, suffer from high message delivery delays due to insufficient routing strategies. They form topologies restricted to a subgraph of the social network of their users by limiting connections to...
Sojourn Time Approximations for a Discriminatory Processor Sharing Queue
A. Izagirre, U. Ayesta, I. M. Verloop
Article No.: 5
We study a multiclass time-sharing discipline with relative priorities known as discriminatory processor sharing (DPS), which provides a natural framework to model service differentiation in systems. The analysis of DPS is extremely challenging,...
