Optimal Coding of Multilayer and Multiversion Video Streams
Abstract--Traditional video servers partially cope with heterogeneous client populations by maintaining a few versions of the same stream with different bit rates. More recent vide...

Think globally, search locally
A key step in program optimization is the determination of optimal values for code optimization parameters such as cache tile sizes and loop unrolling factors. One approach, which...

A scalable auto-tuning framework for compiler optimization
We describe a scalable and general-purpose framework for auto-tuning compiler-generated code. We combine Active Harmony’s parallel search backend with the CHiLL compiler transfo...

Linear precoder design through cut-off rate maximization in MIMO-OFDM coded systems with imperfect CSIT
This paper proposes a linear transmitter design that aims at minimizing the packet error rate (PER) using partial channel state information at the transmitter (CSIT). The design is...
