Building HPC Clusters
In the last installment of our Parallel Platters series, Jeff Layton looks at the next generation of parallel file systems: Object Based File Systems.
As vendors strive for faster processors and denser systems, power and cooling has become a major issue for the HPC market.
The correct choice of I/O & communication interconnects can increase application performance by 2-3x. However, interconnects and their interaction with highly-parallel applications are often not well understood. Learn how the architecture of InfiniBand and Ethernet interconnects impact performance on a variety of applications.
FLOPS are dirt cheap right now. How excited should you really be though?
Now that all of the major processor vendors have introduced multi-core chips, the impact of this relatively new technology on high-performance computing should to be addressed. What will is the immediate impact on HPC application development? And what will "many-cores" ultimately mean for the future of the HPC cluster?
Managing HPC Clusters
Here is your challenge. You have a need for speed, your current computing power is insufficient for the task at hand. You have some large number of calculations to perform, and very little time to achieve this goal. Can you solve this problem? Cost effectively? Quickly?
An often asked question by new HPC cluster users is, What kind of interconnects (networks) are available? This question is important because the network is perhaps the single most important factor in terms of cluster performance. GigE, 10 GigE, Infiniband: Which one is right for you?
What’s stopping clusters from being useful tools?
While implementing and managing a powerful and complex cluster environment can seem like a daunting task, you can make your life much easier and your users more productive by sticking to a few simple rules. Here’s a guide.
Linux clusters have become so successful that they've proliferated internationally through research labs, universities, and large industries that require an inexpensive source of high performance computing cycles. Developers and users have pushed the technology by scaling their applications to more and more processors so that larger problems can be solved more quickly. This has resulted in clusters where some applications can actually become I/O bound -- the input/output of data to/from a large number of processors limits the performance of the application.

Forget the glossy data sheets and single number benchmarks. Get the right information to make the right decisions.
"It's a bunch of scientists that don't know enough about system administration to realize that systems need administration." -- Daniel O. Cummings on scientists with supercomputers.
The ever-increasing demand for storage, network and compute resources for instant access of data and computational requirements lead to the continued growth of the variety of networks found in the data center. HPC is no exception to this trend.
