@lpgaff Thanks man! Should grab a beer next time we see each other in person.

[Wouter Ryssens @WRyssens]

I'm extremely proud to permanently join the nuclear astrophysics team @ULBruxelles with an @frsFNRS mandate.

Het type foto's dat Tanja eigenlijk écht wou posten:

@nuclearIdini I suspect that certain alerts for staff are set too, such that manual overrides can be made. There is a user's day every year and there is everything running from hospital development software to hardcore hydro.

[Wouter Ryssens @WRyssens]

@nuclearIdini No, the standard machines are there for whatever you want them for, development or production, you should check the website. The main stop for abuse is simply the job manager which sets fair use priorities; if you submit too much stuff your priority goes down enormously.

[Wouter Ryssens @WRyssens]

@nuclearIdini Larger machines need project proposals for CPU times on the order of 1M hours and upwards, but those are not so competitive.

[Wouter Ryssens @WRyssens]

@nuclearIdini On the standard machines, there is nothing to write to get CPU hours not in after reporting. The staff is active about cracking down on abuse but there is no a priori accounting.

[Wouter Ryssens @WRyssens]

@nuclearIdini They organize trainings and, on writing a proposal, can get you access on large industry-oriented (Belgian) machines and/or help you get time on EuroHPC machines.

[Wouter Ryssens @WRyssens]

@nuclearIdini I cannot emphasize enough how great this approach is, because (I) it provides a very decent amount of computing in the form that best suits your application to anyone who could need it while (2) putting the general care of systems in the hands of specialized people.

[Wouter Ryssens @WRyssens]

@gleet_tweet @ZenInternetHelp Please forgive me, but your problem is just fascinating. Who would go through the effort to do this to you? Why?

Isn't the most logical answer that there is another P. Stevenson equally as frustrated as you are that is trying to cancel his contract?

[Wouter Ryssens @WRyssens]

@anu_kankainen @SuomenAkatemia @jyflacclab @jyuscience @uniofjyvaskyla Congratulations, great work!

[Wouter Ryssens @WRyssens]

Been a while, but it's paper time 📰! Once more into the breach for BSkG2, the latest large-scale model of nuclear structure of the Brussels group, but this time on the exciting world of nuclear fission!

@PPapakonNucl Ah, Belgian rock history!

[Wouter Ryssens @WRyssens]

@nuclearIdini .... compared to a nuclear one. (Whether you measure this with air superiority or anything else.) On balance, a catastrophic climate impact from war seems to be to most likely to come from nuclear weapons. Only a part of the worlds nuclear arsenals are aimed at deserts!

[Wouter Ryssens @WRyssens]

@nuclearIdini I understand, but your tweet reads like "nuclear weapons don't have the height required, so no problem there". I think (as you do!) that napalm is perhaps more "effective", but such a campaign would need a vast amount of resources ....

[Wouter Ryssens @WRyssens]

@nuclearIdini These authors also claim that a "small" regional war involving 50-100 nuclear weapons is sufficient for global nuclear winter. What do they do wrong in your eyes that makes you doubt their study?

[Wouter Ryssens @WRyssens]

@nuclearIdini I remain sceptical about your claim that contemporary nuclear weapons cannot reach the required height. See O. B. Toon et al. (Atmos. Chem. Phys., 7, 1973–2002, 2007): these authors claim that the weapon itself is not so important for the soot injection, the fire itself is.
