I was under the impression that superdome supports massive parallel computing and hence they are a kind of supercomputer.
Is the above statement true ?
Thanks,
Shiv

Re: Massive Parallel computing
Superdome is high-end UNIX server with superior:
-Performance
-Partitioning
-Connectivity
-Availability
-Mixing processors
The HP supercomputer is a 1,024-node Cluster Platform 4000 based on HP ProLiant DL145 servers with AMD Opteron├в ┬в processors running the Linux operating system. A high-speed Voltaire InfiniBand interconnect is used with HP's XC System Software providing cluster management capability.

Re: Massive Parallel computing
Superdome is defenitely powerful computer capable of parallel processing. Following link may be of help

SolutionIt kind of depends on how you define supercomputer. According to TechWeb's TechEncyclopedia ( http://www.techweb.com/encyclopedia ), a supercomputer is defined as
"The fastest computer available. It is typically used for simulations in petroleum exploration and production, structural analysis, computational fluid dynamics, physics and chemistry, electronic design, nuclear energy research and meteorology. It is also used for realtime animated graphics. See supercomputer sites."
The link to supercomputer sites says
"A compilation of the 500 most powerful computers and their installations was started in 1993 and is updated twice a year. Intended to detect trends and provide reliable tracking of high-performance computing systems, the list uses the Linpack benchmark to evaluate performance and rank the computers. To view the list, which includes system specifications and major application areas, visit www.top500.org."
So, by that definition, a superdome would have to be listed in http://www.top500.org - which it is. At number 252 is a "Integrity Superdome Itanium2 1.5GHz, Hyperplex/640" owned by Cingular Wireless. There are also others.
That makes a superdome a supercomputer.

Re: Massive Parallel computing
But this is probably where the road gets a bit worse, because while You could cross-connect multiple SuperDomes with InfiniBand, it probably won't scale as well as other systems using i.e. cc:numa, which would scale >512 CPUs, but of course this would depend on the I/O requirements Your application has. And, of course, 128 CPUs are really fast anyway ;)

Re: Massive Parallel computing
The HP Superdome (Integrity) offers high-end multi-OS capability that allows running all of the leading operating systems ├в HP-UX 11i, Linux, Windows Server 2003 and OpenVMS (in 2005) ├в on the same system, even concurrently in a consolidated environment. And now, the 128-way HP Integrity Superdome, with 1 terabyte of memory for running larger enterprise applications and with the cell board design/sx1000 Chipset, is available with the HP developed mx2 module ├в enabling the deployment of more Intel Itanium processors.
Cheers,
Raj.

Re: Massive Parallel computing
This is quite surprising to me :)
