Automatic Task Graph Generation Techniques
TLDR
We present a model of parallel computation, the parameterized task graph, which is a compact, problem size independent, representation of some frequently used directed acyclic task graphs. Expand

The Komornik-Loreti Constant is Transcendental
Theorem [Komornik-Loretil. There exists a smallest q E (1, 2) for which there exists a unique expansion of 1 as 1 = ESn=j 8nq n with an E{, 11. Furthermore, for this smallest q, the coefficient 8n is… Expand

Parallel QR decomposition of a rectangular matrix
SummaryWe show that the greedy algorithm introduced in [1] and [5] to perform the parallel QR decomposition of a dense rectangular matrix of sizem×n is optimal. Then we assume thatm/n2 tends to zero… Expand

SLC: Symbolic scheduling for executing parameterized task graphs on multiprocessors
TLDR
We present a scheduling algorithm for a parameterized task graph which first derives symbolic linear clusters and assigns task clusters to processors in a multi-threaded fashion. Expand
