Using trace to solve the multi-core system debug problem

April 7th, 2011 · No Comments

by Aaron Spear, VMware
Modern multi-core designs often aggregate wildly different hardware and software technologies. Traditional debuggers, which show a snapshot of a portion of the system, do little to uncover issues that arise due to complex interaction of components.
Engineers routinely cobble together proprietary tracing facilities in order to have some chance of catching [...]

Researchers claim fix for multicore ‘concurrency bugs’

March 12th, 2010 · No Comments

American computer researchers say they have developed new software which makes programming of multi-processor machines much easier.
“With older, single-processor systems, computers behave exactly the same way as long as you give the same commands. Today’s computers are non-deterministic,” says Luis Ceze, computer science and engineering prof at the University of Washington, Washington. “Even if you [...]

Reconfigurable Computing Research Pushes Forward

November 23rd, 2009 · No Comments

Despite all the all the recent hoopla about GPGPUs and eight-core CPUs, proponents of reconfigurable computing continue to sing the praises of FPGA-based HPC. The main advantage of reconfigurable computing, or RC for short, is that programmers are able to change the circuitry of the chip on the fly. Thus, in theory, the hardware can [...]

Multicore Storage Allocation

November 6th, 2009 · No Comments

by Charles Leiserson
When multicore-enabling a C/C++ application, it’s common to discover that malloc() (or new) is a bottleneck that limits the speedup your parallelized application can obtain. This article explains the four basic problems that a good parallel storage allocator solves:
* Thread safety
* Overhead
