Sea of ‘wimpy’ cores may sink you

September 17th, 2010 · No Comments

Google is the modern data poster-child for parallel computing. It’s famous for splintering enormous calculations into tiny pieces that can then be processed across an epic network of machines. But when it comes to spreading workloads across multi-core processors, the company has called for a certain amount of restraint.
With a paper (PDF) soon to be [...]

Intel tools harness the true promise of multicore chips

September 16th, 2010 · No Comments

by Neil McAllister
Multicore chips achieve performance gains through parallelism, but parallelism in software doesn’t come for free. Before an application can take advantage of today’s multiprocessor architectures, developers must build support for parallel task and data management at the lowest levels. Unfortunately, many of today’s developers learned their craft at a time when this level [...]

Let’s go beyond the CPU to the GPU

September 16th, 2010 · No Comments

By Margaret Lewis
Traditionally, the way we think about software development is that you have a CPU (central processing unit) and a GPU (graphics processing unit), and each is good at handling certain sets of tasks. The x86 CPU is good at executing a sequence of stored instructions, and even has the ability to handle multiple [...]
