Update resourcesdir todi.py

[lucamar]

Provide folder with resources on Todi, that would be required for some applications (e.g. NAMD)

Thanks @lucamar!

Hi @lucamar and @RMeli . After discussing it in vcue, we decided to not use the resourcesdir anymore in the new systems, unless really necessary. (We have a note in the bottom of this confluence page, in section "Adding larger resources to the tests"). The idea is to make it more portable by moving resources to jfrog, whenever possible.

For this reason we created this directory in jfrog that is open and you get simply wget <jfrog_url>. From what I could find, we only need a few MB of data for production tests (including NAMD) so the pulling should be very quick.

I believe cscs staff can push to the directory (with credentials), but then pull without. Please have a look and let us know if you still think that we need the resourcesdir.

Thanks @ekouts, I'll add the necessary machinery in #245 to download the resources from JFrog.

Yes, I think this is indeed the case. The NAMD test already needs to accesses JFrog to download the source code (because of licensing), so the credentials need to be set in CI anyways (see #245).
