 If you share my screen I can give you the executive summary like this kind of, if you have to give it to the CEO or somebody like? Executive summary what are the bullet points that you need to know, not fancy much about this system is that module system is every cluster has their own software installed, It depends on the cluster, but almost all of them use these modules to make it available for the users. So what are the modules? They are basically like a fancy way of loading software. It's fancy on the bottom, like it's fancy for the execution is fancy, but the usage is very simple. So like Richard in his example had, he had this module purge command, so there is good command to make certain that I have no modules loaded. You can use module list to check if you have any modules loaded, and then you can run module load to load a module. And what are the modules? They are basically like shortcuts to different programs, and every HPC cluster provides their own list of programs. So we have a bunch of programs here in the applications page. We have a huge bunch of programs, CSC has a huge bunch of programs, other sites have a bunch of programs, lots of programs, everybody installs them, and they provide them with these modules. So let's say we want to load MATLAB. We want to have MATLAB available to us. In our system, we module load MATLAB, and if we now run module list, we have a MATLAB loaded. What does that mean? It means that now we have MATLAB command available to us, and we can run MATLAB. So usually you just have, you can look at the applications page for a specific application that you want to use, and you can then load the relevant module and use that application. It's as simple as that basically, and going to too much detail would be disservice to the whole system I'd say. If you want to search for available modules, you can run module spider, and this will produce you with a huge list of software. I guess you can module spider for a certain name somehow. Yeah, you can module spider for example MATLAB, and it will give you different versions of MATLAB that are available. Or you can use this module available to produce this list as well. That will be a big list of software. But I would recommend before loading some simple module, I would probably go to the documentation and check the application page if there's an example on how to use the specific application. So that's the better way of doing it. We have in our information, where is it? Under Triton, we have a whole application section which lists many things which need special instructions somehow. Okay, so yeah, is that it for modules then? Yeah, so the actual chapter has more information, more commands, like you can check various things. But really what you need to do is that if you want to use some program that we have already provided for you, and you probably should because we usually try to test them out and make them as easy to use in the system as possible. So if there's such a program available, if the application page gives instructions, use that. If you can just load the module, try that, and then play around with it and give us a hint or give us an issue if the software doesn't perform as you expect. It's usually a good idea to just run a quick search through the documentation or the module avail to check if there's available software. And if it isn't there, then let us know if you want it to be installed by us or if you want health finding. Yeah. What about if something's not in module? Is module the only way of getting applications? No, of course you can install applications yourself, like many people do it. But usually, especially the more complex application, the harder it usually is to install. And some applications are really hard to install. So that's why we try to provide them centrally so that it helps everybody and nobody, like people don't have to hit the head in the brick wall installing. And we can do the heating ourselves. But of course you can install a software yourself as well as yourself. I think I remember one person yesterday in the icebreaker question. They said they wanted to use singularity on Triton. Should we talk about that now or later? Maybe later? Yeah, I think later. That's an advanced kind of word. If you're interested in that, I would suggest coming to the garage. That's probably the case, because it becomes advanced stuff immediately. We do have pages on singularity. And with what you're learning now, you should be able to read that page and do it pretty quickly.
