[News] Linux Clusters Parallelised to Become Supercomputers

ScaleMP touts cheap Linux multi-processors

,----[ Quote ]
| Software company ScaleMP is claiming to have turned virtualisation on its 
| head - instead of making one server look like several, it said that it can 
| make a cluster of entry-level servers look like a single high-end machine.  
| 
| Called Versatile SMP (vSMP), its software is a kind of pre-boot environment 
| which loads from flash and uses Infiniband for connectivity. The clustered 
| servers then appear as a symmetrical multi-processor (SMP) system, and can 
| run standard multi-processor versions of Linux, said Shai Fultheim, ScaleMP's 
| founder and CEO.    
| 
| He said that while the server aggregation happens in software, like other 
| clustering schemes, vSMP is below the operating system, not on top of it, 
| which reduces the overhead involved.  
| 
| "With [traditional] clusters, you need to work at the operating system or 
| application level to parallelise it, and you have to set up a cluster file 
| system and job scheduler," he explained.
