So Your Processor has Multiple Cores -- Now What? · 239 days ago
It is nearly impossible today buy servers or desktops that do not have processors with multiple cores.
The use of several cores has gone from an important innovation to a universal feature in two years’ time. (Technically, non-x86 processors had multiple cores before this time frame, but the concept was not mainstream until the x86 vendors — Intel and AMD — picked it up.) As a result of this ubiquity, sites that are buying new servers need to begin considering the effect of multiple cores. Read more…

The prescient Amdahl · 240 days ago
This week GCN has a feature story on how programmers can write their programs to get the most out of multicore processors.
The problem is only partially about how to break up the problem in such a way that it uses all the processor cores you have available. That’s complicated enough, but there is an additional trick—you must break up the problem in such a way that any gains in efficiency aren’t eaten up by the overhead it takes to manage the execution across numerous cores.
