run relax at cloud.sagemath.com

Try relax at cloud.sagemath.com

This tutorial shows how to get relax running at cloud.sagemath.com.

cloud.sagemath.com is optimal for

fully functional linux and python environment
online accessibility
rapid installation of relax
testing purposes
teaching

cloud.sagemath.com is not the optimal for

long-time calculations stretching over several days
multiple CPU's (above 4 CPU's )

pricing

The benefits are well explained here: http://www.sagemath.org/library-why.html

The meanings are

Member hosting: This lets you move a project to a members-only server, which has much less load. If you have 16 of these, you can move 16 projects. You can change which projects you move at any time, though it can take a little while to move a project (depending on load).
Network access:' This makes it so your project has 100% access to the whole internet, so you can connect to any external website. Otherwise, there is a small whitelist of sites (e.g., pypi, github) that a project may connect to.
Idle timeout You can allocate time between projects so that if you just shut your browser and come back (or aren't active), the project will continue running your code instead of just shutting down. By default, projects top running after 1 hour of not being actively used through a web browser.
CPU shares: This allows you to increase your priority relative to other users on the same computer. So if the system is loaded, your code will run a bit faster than other users.

Sign-up and ssh to account

Do the following

Go to https://cloud.sagemath.com/
Sign-up for account. Note, you don't even need a "working e-mail", as no confirmation mail is send. It just works.

Establish file access over SSH

At your own computer, create a SSH-keypair.

tlinnet@linmac:.ssh$ ssh-keygen
