System noise, OS clock ticks, and fine-grained parallel applications
As parallel jobs get bigger in size and finer in granularity, “system noise” is increasingly becoming a problem. In fact, fine-grained jobs on clusters with thousands of SMP...

Parallel sparse LU factorization on second-class message passing platforms
Several message passing-based parallel solvers have been developed for general (non-symmetric) sparse LU factorization with partial pivoting. Due to the fine-grain synchronizatio...

Tasking with out-of-order spawn in TLS chip multiprocessors: microarchitecture and compilation
Chip Multiprocessors (CMPs) are flexible, high-frequency platforms on which to support Thread-Level Speculation (TLS). However, for TLS to deliver on its promise, CMPs must explo...

A NUCA substrate for flexible CMP cache sharing
We propose an organization for the on-chip memory system of a chip multiprocessor, in which 16 processors share a 16MB pool of 256 L2 cache banks. The L2 cache is organized as a n...
