Data mining and fast queries are always in that bin of hard to do things where doing something smarter can yield big results. Bloom Filters are one such do it smarter strategy, compressed bitmap indexes are another. In one application "FastBit outruns other search indexes by a factor of

There are a lot of questions about the server components, and how to choice and/or build perfect server with consider the power consumption. So I decide to write about this topic. Key Points: * What kind of components the servers needs * The Green Computing and the Servers components. * How much

Hello highscalability world. I just discovered this site yesterday in a search for a scalability resource and was very pleased to find such useful information. I have some questions regarding distributed caching that I was hoping the scalability intelligentsia trafficking this forum could answer. I apologize for my lack of
We are at the beginning of the multicore era. Computers will have increasingly many cores (processors), but there is still no good programming framework for these architectures, and thus no simple and unified way for machine learning to take advantage of the potential speed up. In this paper, we develop

Scale-up solutions in the form of large SMPs have represented the mainstream of commercial computing for the past several years. The major server vendors continue to provide increasingly larger and more powerful machines. More recently, scale-out solutions, in the form of clusters of smaller machines, have gained increased acceptance for

The Gear6 Web Cache hybrid DRAM-flash memory architecture allows for 5-10 times more memcache memory per unit of rack space than DRAM-only configurations, and cuts memory costs by 50%. Other software enhancements include a slab allocator that is more efficient than traditional memcache implementations due to its fine-grained bucket sizing.

I just saw this article in HFadeel blog that spaek about Parallelism in .NET Framework 4, and how Thread Pool work, and the most faoums scheduling algorithm : Work-stealing algorithm. With preisnation to see it in action.
