Hello. I wrote here to start a new ptoject around the arallel computing in linux. I am learning onto a cluster made by single board computer to have my house as less buisy as possible. The project is at first to learn, and then creating a linux cluster.
The needed is not a cluster around webservices as apaches. The final work of the cluster will be not internet services and not internet vps. It should be a workstation for only one person. The project is to make an user see an only one computer with a lot of cores working together.
For example: comuter 1 = 8 cores,Ram 8Gb, Disk 500 Gb; computer 2 = 8 cores; 8Gb ram; 500 Gb disk. The cluster will be: 16 cores; 16 Gb ram; Disk distribuites with 500 Gb or 1Tb,
The software to do that? Docker? Kubernetes? Ansible? There is a galaxy around cluster software. Ho is it the road to implement a workstation in parallel computing? Many thanks.

Hi.

I've planed on something like this some day too...

Distrowatch has a search ("Distribution category") for cluster to start you down the opinions(, mine: Debian-Sid-netinst-CLI--to start).

...and, a net search not including Pi xx (or whatever SBP:) could go:
how to build a cluster?

Have fun!

It depends on your goals. You want parallel computing but not every task works that way. You can not magically combine the memory of each node into a single supercomputer, a cluster is for horizontal scaling, i.e. running the same thing multiple times. It will not run games or a web browser faster.

This leads my search to:
what can I use a cluster for

e.g: http://etutorials.org/Linux+systems/...Use+a+Cluster/

Hi. Thanks for your patience and your replyes. I found your links very usefull. I am making experiments to create a cluster. The cluster could be used both to have a securely online machine (if a node goes down there are the others that will run); and a parallel working. The sum of computational threads will given to a VPS that will be the only one computer that I will see. This machine will be an experiment in a room with a isolated network and six or seven normal PCes. This experiment is done to learn and study the VPS system. I had a VPS on Linode. The help service operator told me that the core are representative of a number of threads that they rent us; the VPS cores, listed in the prices vps page, are not fisical cores. I learned that they use Virtuozzo. They have a big machines farm and they rent VPSes. Every customer runs a CLI where he can operate and where he can enjoy his threads.
I would like to create a cluster that runs and mantain alive an ONLY one VPS. That VPS will be the only one machine that I will use. I have a clear project but I am a little confused around the software that I could use for.
Many thanks for this mind crusade, and I hope to have friends here to learn from and to operate with!!
The project is a plan that will contibute to crypto-tokenize a company. Many thanks.

Thanks for the tutorial link. In the chapter 10 there is the PVM description and implementation. This is what I mean. I am beginning to this. But the software in this case can be choosed correctly.
