Ok , lemme explain it a little bit more. What i want to do is buy some processors from market( may be 8 or 16 ) and using these processor, build a single processor. Everything else ( like mem, HDD ) should be common.   I dont have any previous knowledge of this, just came to know that this can be done, so thinking to doing so Any help is appriciated.

You can put them in one computer, but things like on-chip cache will always remain separate to each individual processor.   What you need is a motherboard you can plug them all into, or some way of extending a motherboard so you can plug in more CPUs.   e.g. http://www.geek.com/articles/chips/amd-shows-off-8-cpu-system-with-four- socket-motherboard-20040831/ IP Logged Wikipedia, Google, Mathworld, Integer sequence DB birbal Full Member     Gender: Posts: 250 Re: building multiprocessor   « Reply #5 on: Jan 31st, 2010, 8:59pm » Quote Modify thanks towr, this link is indeed helpful. I have heard there is some LAN technology with which we can make processors communicate, without actually putting them all into one motherboard. Please share if you have any knowledge of this.   Also i would like to know about the software/OS with which we can control the concurrency.

There are MPI libraries for several programming languages, and they allow you do do parallel computing over a LAN (or other similar setups) You can also look up clusters for other similar technologies for harnessing the power of multiple computers toward the same end.

LAN technology and MPI is something i was looking for. Can you give me idea how should i approach in building this system, it will be of great help.

But I think it's just a matter of connecting the computers via a switch and installing the appropriate software on them.   Here's a how-to for a beowulf cluster: http://clustercompute.com/ (although it's ten years old) Here's another one: http://www.mcsr.olemiss.edu/bookshelf/articles/how_to_build_a_cluster.ht ml     [edit]Another good article: http://www.hpccommunity.org/f55/so-you-want-build-cluster-five-things-co nsider-before-you-start-578/ [/edit] « Last Edit: Feb 2nd, 2010, 4:53am by towr » IP Logged Wikipedia, Google, Mathworld, Integer sequence DB Pages: 1  Reply Notify of replies Send Topic Print Forum Jump: ----------------------------- riddles -----------------------------  - easy   - medium   - hard   - what am i   - what happened   - microsoft => cs   - putnam exam (pure math)   - suggestions, help, and FAQ   - general problem-solving / chatting / whatever ----------------------------- general -----------------------------  - guestbook   - truth   - complex analysis   - wanted   - psychology   - chinese « Previous topic | Next topic »
