Managing the complexity of lookahead for LU factorization with pivoting
We describe parallel implementations of LU factorization with pivoting for multicore architectures. Implementations that differ in two different dimensions are discussed: (1) usin...

Buffer-space efficient and deadlock-free scheduling of stream applications on multi-core architectures
We present a scheduling algorithm of stream programs for multi-core architectures called team scheduling. Compared to previous multi-core stream scheduling algorithms, team schedu...

A universal construction for wait-free transaction friendly data structures
Given the sequential implementation of any data structure, we show how to obtain an efficient, wait-free implementation of that data structure shared by any fixed number of proces...

On the bit communication complexity of randomized rumor spreading
We study the communication complexity of rumor spreading in the random phone-call model. Suppose n players communicate in parallel rounds, where in each round every player calls a...
