== Purpose ==
Why ?
* The first installation of '''relax''' can be an energy barrier
* It could be of interest to make relax available in "the cloud" for the first analysis, so time is not used on solving software dependencies
Problems with "the cloud"
* Very time consuming to "run an online" cloud.
* The benefits of cloud.sagemath.com are well explained here: http://www.sagemath.org/library-why.html
Other info
* The prizing is here: https://cloud.sagemath.com/policies/pricing.html
* There is also the Bio-NMR initiative: http://www.bio-nmr.net
* And a web service with all NMR software - WeNMR: http://www.wenmr.eu
== Possibilities with cloud.sagemath.com ==
cloud.sagemath.com currently don't provide admin account or dedicated SMC servers. <br>
A purchase for a subscription for $ 49 / month (or $499/year), one can apply the quotas listed here to any projects:
* 16 upgrades Member hosting
* 40 upgrades Network access
* 8 days Idle timeout
* 24 GB Memory
* 40 GB Disk space
* 4 shares CPU shares
* 2 cores CPU cores
The procedure should be
* A "new interested scientist" would go to SMC, create a project.
* Add "relax" as a collaborator to their free project, and "we" would click a button to upgrade their project to "member hosting".
* This add '''network access''', increase the cpu shares, etc.
* "We" have a page which lists, for each project, what upgrades "we" have applied
* "We" can also see if the project is being used.
* "We" can remove upgrades at any time (in any granularity).
The value of upgrading to "member hosting" is:
* Computation is '''much''' faster. The free pool of computers are typically '''massively''' loaded during the week.
* The "free servers" work fine, but they can easily be 15% of the speed of the members-only machines.
* With the $49/month subscription, "we" get to move 16 projects to members-only machines.
Installation of relax in cloud.sagemath.com
* Instead of making "relax" available for all users on cloud.sagemath.com, each user should install their local copy of relax
* When using svn to checkout relax, there will be a: install_relax_cloud_sagemath_com.sh bash script
Analysis
* Use ssh to send data to the server
** Supported right now, even for free projects. See the button "ssh to your project" in project settings.
* The uploaded data for the researcher is private:
** Even for free projects, data in projects is only visible to collaborators on that project and nobody else. SMC is not like github,
where free = public by default. With SMC everything is private by default, even for free users.
** However, people can also explicitly share any file or directory tree, and that makes it publicly available
(so good way to share data related to a paper or research project).
