Re: [riot-devel] Mailserver issues

[Adam Hunt]

What sort of hardware would RIOT need for CI? Would a machine with,
for example, a pair of E5-2670 (eight cores @ 2.60 GHz), Xeons between
64 and 128 GB of DDR3 ECC RAM, an SSD or two, and maybe some spinning
storage suffice or are we talking about something like a highly
available cluster consisting of half-dozen or more HP ProLiant DL380
Gen10 machines each with a pair Xeon 8100s (28 cores @ 3.60 GHz), a
terabyte of DDR4 RAM, and a pile of blazing fast NVMe drives?

I'm just thinking that if a machine or two with specs closer to the
first example would suffice than I imagine the RIOT community might be
able to find a way to make it happen.

A word of warning… While I'm absolutely serious about trying to help
out in this area (and other) please know I'm currently trying get the
ball rolling and determine what type of resources the project could
most use; it'll take a bit of time to turn these early thoughts into
something real. Personally, I may not have piles of cash laying around
but I do have something else of value, time.

To offer an alternative, I can offer the services of Studenten Net
Twente[1]. Studenten Net Twente is a student associations of the
University of Twente aimed at providing IT services. We have a history
of supporting open source projects by offering FTP space and/or
colocation services for free.

As we use RIOT-os for an internal project, we'd love to return something
to the project. If a host for CI or other services is needed, I can see
if I can get a virtual machine or some real hardware available for
RIOT-os infrastructure.

They also offer to host a server of your own. We do that for the 
Enlightenment project for several years now. Their connectivity and 
general admin service has worked very well for us.


We have a beefy server there hosting our own tons of git repos, web 
services, downloads, CI, etc. I don't think there is any bandwidth 
limitation or such. All in all a really nice service from them to the 
open source communities.


If it is something interesting for RIOT I have no idea but if you are 
looking for something in that regard it is surely worth talking to them.

I'm not affiliated with OSUOSL, I just live in their area.

Actually not. In fact, the maximum number of MTA and content filter processes
were configured too low.

Currently, some of the services (e.g., web and mail) are hosted privately by
community members, other services are sponsored by supporting institutions
such as FU Berlin, HAW Hamburg, and Inria. In general, additional resources
are always helpful, particular for the CI system, I guess. Do you have
something particular in mind?

Oleg

Just out of curiosity, was this due to a lack of machine resources?
How is RIOT's infrastructure (e.g. web and mail hosting) handled; is
the hosting donated by one or more of the supporters listed at the
bottom of the project's homepage? Would additional hosting resources
be helpful?
