Developers must face parallel programming issues

August 31st, 2008 · No Comments

David Stuart, the CEO of Critical Blue, writes an article on EETimes Asia saying that his customers are deploying multi-threaded software onto multi-core platforms. They’re not using new languages or tools, just applying their brains to the problem, and launching products to market at an amazing rate.
Don’t get me wrong. Academic research is vital, and [...]

Multicore Multifiasco?

August 30th, 2008 · No Comments

In response to Dave Patterson’s thoughts on multicore challenges and the rationale for increased government funding to solve them, Philip Machanick of the University of Queensland wrote a comment. He listed four lessons about parallel programming that were learned but forgotten. They are:

parallel programming is inherently hard, and tools and techniques claiming to avoid the [...]

Parallelism matters

August 30th, 2008 · No Comments

Here is a blog post by Jonathan Edwards, whose previous post (Too many cores, not enough brains) got some attention, now admits that parallelism matters.
latency can often be a more important issue than raw speed, and requires parallelism even on single-core processors. Performance tuning is often only needed in small regions of code, but latency [...]

SSDs not ready for ’storage-class’ apps

August 29th, 2008 · No Comments

Solid-state drives (SSDs) are promising, but the technology may not be ready for prime time in higher-end enterprise or ‘’storage-class” applications, according to an analyst.
For these high-end, ‘’storage-class” applications, NAND-based SSDs could hit the wall. Instead of using NAND, phase-change and resistive memory technology looks more promising in storage devices, said Bob Merritt, an analyst [...]

Researchers create quantum repeater

August 29th, 2008 · No Comments

Scientists from Austria, China and Germany have implemented a stable quantum repeater. The device has the potential to obtain a central function in future quantum effect-based communication networks.
The quantum repeater could counteract the signal attenuation on long-distance data transfers, the researchers said. While in electronic networks, amplifiers and filters that regenerate the signal after certain [...]

Nvidia 55nm parts are bad too

August 29th, 2008 · No Comments

HOT ON THE heels of its denials that anything is wrong with the G92 and G94s comes another PCN that shows the G92s and G92b are being changed for no reason. Yup, the problems that are plaguing G84 and G86 are the same that affect seemingly all 65nm and now 55nm Nvidia parts.

Ecosystems Are Messy

August 29th, 2008 · No Comments

HPCWire has an article that talks about current messy state of IT Ecosystem.
“The ascent of the x86 architecture took place at a time when the computing ecosystem was reasonably stable — the 1970s through 1990s. Applications written in serial programming languages like C, Fortran, and COBOL automatically got faster with each passing year as clock [...]

Bridging options enable FPGA-based configurable computing

August 28th, 2008 · No Comments

As PCI Express continues to invade embedded systems, the history of legacy PCI is repeating itself. The twist is that FPGAs have taken on processing tasks within many embedded systems, augmenting or displacing dedicated processors and DSPs. Consequently, FPGA endpoint bridging solutions for PCIe must enable the FPGAs to truly fulfill their new role.
For common [...]

Atom is Just the Beginning

August 28th, 2008 · No Comments

While Intel picked up some market share in the PC world after AMD stumbled on product development over the past year, most of its growth prospects still revolve around computers. But compared with handsets, which continue to blanket the world in ever-increasing numbers, the market for computers is relatively flat. Most of it has become [...]

Parallelism for paranoids or what?

August 28th, 2008 · No Comments

Here is a blog post asking whether the parallel programming techniques take off their old academic clothes and dress in some new fashion that is friendlier to common developers? An excerpt from the post:
“That is actually a derived question brought up by some professors in their presentation about the evolvement of parallel programming and what [...]
