Automate jobs submission in Slurm

Previously, I've posted about a simple script that I used for running MD simulations. This script recursively submits the same instructions to PBS. Nothing complicated, but it's really useful for me. Lately I've been working with another scheduler, namely Slurm. So, I've adapted the PBS script and I made it simpler. I just need to write a script and then submit the jobs to Slurm using this…

My new mailbox

I did it, I've finally have a new inbox further away from Google filthy hands! Despite having an address with a custom domain, my email was still operated by Gmail which means: lack of privacy, profilation, painful user experience and data outside of EU borders. If you have no idea about how Google processes your data, please take a look at this tosdr page . In order to regain control of my own…

Being almost offline

I've never been obsessed with social media, however I had an account both on Facebook and Instagram. When those platforms still had the social aspect, it was fun scrolling through my friends' stuff, react and engage with them, it was a mean of communication. Nowadays, I don't see much value in it as any networking capabilities have been buried with ads and attention seeking content. While I've…

Automate the submission of MD simulations

In our research group we recently faced a problem with our cluster. Basically, most people started to submit jobs that took months to complete, thus making impossible for everyone else to submit even small jobs. We use PBS as queue manager and even tweaking with its config the problem was not solved. The obvious solution is to split a long job in small pieces, however that can be tedious to do by…

I guess we'll have a spaceport

Although I've spent the last five years in Bologna and Pisa, the place that I consider home is Salento (Puglia, IT). This is where I was born and I belong, so my desire is to come back there eventually. Southern Italy is different from the north, Italy is basically divided in two parts with the south being the poorer and generally excluded from the industrialization and innovations of Central…

I've joined a webring

Table of contents _ I've always complained about the decay of web, and more generally of technology, that we've seen in the past years. I'm not going to talk about that here, as this topic has been discussed over and over (more recently on tildes.net ). What I'm going to tell you is that I've joined a webring! What is a webring? Well, in simple terms a webring is a circual structure where websites…

Implementing Monte Carlo in Python

Table of contents _ As a bioboy I'm interested in the study of biopolymers' (e.g. proteins) conformations and interactions. These systems are incredibly complex and pose difficult challenges to both experimental and computational researchers. Lately I've been introduced to the application of Monte Carlo (MC) methods to the study of such systems, and I'm amazed by how a conceptually simple method…

Getting notified after a workload finishes

Hey! A couple of days ago I started working on the research project for my master's thesis (more on that in the future). I started doing some calculations that are taking days to complete, so I thought it would be nice to remind my fellow biophysicalchemistry-enjoyer that you could do some bash scripting to get notified after a job is done. In that way you could do some bibliographic research…

I created a game in two days

Hey all! Lately I was feeling a little bit overwhelmed by things to do and everyday life. I needed something new to try to distract myself, so I've decided to download the Godot game engine and create a little game. I chose Godot because it's free and open-source, I knew nothing about it. It's a great engine, easy to learn, but at the same time incredibly powerful. To motivate myself, I've even…

Learning Physical Chemistry

Table of contents _ Physical Chemistry is, in my opinion, the most beautiful declination of Natural Sciences as it lets you describe whatever physical or chemical phenomena. Mastering this discipline empowers you the ability to look at the world in a special way, the same way an artist observes it, but using mathematical lenses. I would like to dedicate this space to a not-complete and subjective…

Hello World!

Hey you! If you are seeing this you are a curious person and you are probably wondering what I am doing with this website. Well, this is a I don't rememberth -iteration of the website, but nothing really changed from the others. I really wanted to start a blog or something, but I never had the time to do it. In the past I have published some science-related content, but I'd prefer to leave this…
