RE: Citizen Science on Hive: Report #2 - (A bumpy road to) simulate particle production at CERN’s LHC
You are viewing a single comment's thread:
I was definitely expecting for your report. When I saw it I was quite excited. Before reading it, I had two questions popping up from my mind:
- Have you managed to solve all disk space issues?
- Has everything gone fine this time?
It was cool to then read the report and see that "yes" was a good answer to both of these.
As for the last report you wrote, I really appreciated all the details you put, that I imagine will be useful for others reaching in the same problems (maybe in the future, if we have new people joining us; who knows...).
And now let me share my two comments. First of all, note that report2 as a name for the working directory is fine. We will use this one for a couple of episodes before starting to generate the real deal. There, it will be important to monitor what you generated closely. For this purpose, appropriate folder names definitely help. But here, we are still in a "tutorial mode" so that can still be a little disorganised.
I was a bit puzzled, then I discovered that yes, the 10GB I assigned as maximum space were really over. I created my virtual disk as Dynamically allocated, but that does not mean it is infinite, you have to assign a maximum space, so guys, remember to take something bigger than 10GB.
If I remember well, a large chunk of this 10GB is taken by the operating system. The simulation we performed should take more or less 1 GB. Do you mind confirming this? Thanks in advance!
PS: I was pleased to read you met Fortran at the university. This means that we may be of a similar age ;)
Thanks for the words! Definitelly this took a bit longer, I had to leave it for the weekend and the small issues and waiting times did not allow to feel I was working continuously on it. It is fun how it looks now that the problems were so small, once you know the answer everything is easy.
By the way, I have updated the original post for Report #1 to add a note on the HDD size and the need to install numpy.
Regarding the disk usage, I can confirm you that most of that space is the current basic installation of Xubuntu+basic packets (but python, fortran, C, make and so on are not so heavy), maybe close to 7GB. The MG5_aMC folder is only about 1.4GB and this weeks output below 1GB.
I started univeristy in the mid 2000s, there everyone thought Fortran was already too old school, just an excentricity. Later on, I had to pass mostly to Octave and Matlab and... a lot of easy solutions on Excel + VisualBasic (yes, I became that high level kind of people). Only this year is the moment I am modernizing myself and starting to use little python scripts. And python, that now looks omnipresent... was never in almost any conversation for us.
Btw, I need to find some time to try to write some of my normal posts, I want to update some of the topics I was covering the last months. But I also hope that the next episode of this project comes soon! I guess last week with so many days off... will not leave me so much time to write.
I would love to read again some of your normal posts too. There is however only 24 hours in a day and 7 days in a week, and there is not much we can do about it. However, don't worry, the next episode of the citizen science projet will be a bit lighter than the previous one, so that I won't take too much of your time ;) The reason is that we need to deal with the installation of another program (which may be super quick for some, but rather slow for others, depending on the system and how linux is mastered).
PS: I am definitely from the same generation as you, and I have experienced the same situation relative to programming. I was studying at the university during the end of the 1990s and the first half of the 2000s. Now, I am mostly dealing with codes in Python and C++. However, Fortran is still there a lot, in particular in the core of MG5aMC :)
