The Limits Of Virtualization


By Ed Sperling The future of virtualization in the corporate data center is firmly established, but questions about the value of virtualization beyond that world remain as fuzzy as the future of many-core systems. While there is no theoretical limit to how many cores can be added into SoCs, there is very little progress in developing applications that can take advantage of all of those core... » read more

Experts At The Table: Coherency


System-Level Design sat down to discuss coherency with Mirit Fromovich, principal solutions engineer at Cadence; Drew Wingard, CTO of Sonics; Mike Gianfagna, vice president of marketing at Atrenta, and Marcello Coppola, technical director at STMicroelectronics. What follow are excerpts of that conversation. SLD: We’ve been hearing a lot about Wide I/O. Why is it so important and what effec... » read more

Power Shift


By Ed Sperling For the past decade, most of the real gains in energy efficiency were developed for chips inside mobile electronics because of the demand for longer battery life. Dark silicon now represents the majority of mobile devices, multiple power islands are commonplace to push many functions into deep sleep, and performance is usually the secondary concern for most applications. Whil... » read more

Making Sense Of Virtualization


By Achim Nohl In the last month I’ve had the opportunity to get some hands-on experience with hardware virtualization and hypervisors. My knowledge so far on this has been mainly limited to what I could read about it and what other people are saying about it. However, the PowerPoint slides I’ve seen leave a lot of white fog between the bullet items. This didn’t make me feel very comfo... » read more

Why PCs And Servers Aren’t Going Away


By Pallab Chatterjee With the rise of mobile appliances, smart phones and tablets, there has been a lot of discussion about the place for PCs, servers, embedded processors and networks. A number of companies have claimed they will rule the world of computing and there will no room for others. Reality seems to be somewhat different, however. The mobile end point devices—smart phones, table... » read more

Deja Vu All Over Again


Every now and then you get the feeling you’ve been here before, and with technology this is a persistent theme. Virtualization looks remarkably similar to time sharing, which is what most engineers in their 40s and 50s used when they were in college. And 3D stacking, particularly the 2.5D version, looks eerily like the old MCM, aka multi-chip module. There’s nothing wrong with resurre... » read more

Virtualization In Your Hand


By Ed Sperling The addition of multiple cores inside of computers has created an enormous opportunity for virtualization. Instead of running one operating system or one application, a single server or multicore PC can run multiple virtualized OSes on a single machine at the same time. From the standpoint of energy efficiency, this has been a huge gain in data centers and the corporate ent... » read more

Greener Data Centers


By Ed Sperling For decades the race inside the data center was all about performance. If you upgraded from an IBM Series/370 mainframe to a Series/380 your applications ran faster. And if you upgraded your PC server from a Pentium II to a Pentium 4 you got significantly better performance. The race now is to reduce the number of servers altogether, to lower the cooling costs per server ra... » read more
