Can a File System Virtualize Processors?

Overview Supercomputers comprise more and more processors and these processors are increasingly heterogeneous, with differing performance characteristics. The conventional programming models assume that all nodes run in lockstep. Thus, applications run at the speed of the least powerful processor. This paper introduces DesyncFS, a new programming model based on the block abstraction of traditional file systems. It virtualizes the performance characteristics of processors; this allows their heterogeneity to be hidden. The paper shows that DesyncFS allows cluster throughput to scale with average processor throughput instead of being limited by the slowest processor.

SGI to unveil new supercomputer

The density of the Origin 3900 is largely accomplished through the low-energy characteristics of the company's MIPS processor, which consumes about 17 watts, about the same as a notebook chip. The Origin 3900, which SGI will also show off at the...

IBM to build fastest supercomputers yet

The design details of Blue Gene/L still haven't been settled beyond a plan for it to have 65,636 computing nodes, said Peter Ungaro, IBM vice president of high-performance computing. For enormous systems with thousands of processors, a major...

Sun and Fujitsu merge Unix server lines

Sun cancelled development of its high-end UltraSparc V processor earlier this year, a move that wasn't related to the Fujitsu deal, said Marc Tremblay, Sun fellow and chief architect of the company's processors and network products.

IBM to sell supercomputing server

And those 12 computing nodes consume up to 41.6kW. The p5-575 combines eight Power5 processors and as much as 32GB of memory into a computing slab 8.9cm tall, 61cm wide and 127cm deep. Each system uses eight 1.9GHz Power5 processors.

IBM targets Sun with entry-level Unix servers

Fifield said: "The smaller size of the processor and the lower heat output it gives is one of the main design gains of these the new processors and the new systems. It uses a 30 per cent smaller processor size - 90nm rather than the 130nm in the...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
