LHC@home

CMS never runs test units, not even on the dev server.

Like I said, one CPU per WU. Or as Preferences phrases it, "Max # of CPUs for this project" = 1.

<app_config>
<app>
  <name>ATLAS</name>
</app>
<app_version>
    <app_name>ATLAS</app_name>

    <avg_ncpus>1.0</avg_ncpus>
    <cmdline>--nthreads 1</cmdline> 
</app_version>
</app_config>

Now I get an error in BOINC:

"LHC@home: Notice from BOINC
Your app_config.xml file refers to an unknown application 'Theory'. Known applications: None"

Any comments you have on this would be welcomed.

The proton, a particle found at the heart of every atom, appears to have a more complicated structure than is traditionally given in textbooks. The find could have ramifications for sensitive particle physics experiments like the Large Hadron Collider (LHC).

Has anyone else had this issue with the latest release of Mint / Ubuntu?

The hunt for new physics is back on. The world’s most powerful machine for smashing high-energy particles together, the Large Hadron Collider (LHC), has fired up after a shutdown of more than three years. Beams of protons are once again whizzing around its 27-kilometre loop at CERN, Europe’s particle-physics laboratory near Geneva. By July, physicists will be able to switch on their experiments and watch bunches of particles collide.

In its first two stints, in 2009–13 and 2015–18, the LHC explored the known physics world. All of that work — including the triumphant 2012 discovery of the Higgs boson — reaffirmed physicists’ current best description of the particles and forces that make up the Universe: the standard model. But scientists sifting through the detritus of quadrillions of high-energy collisions have yet to find proof of any surprising new particles or anything else completely unknown.

This time could be different. The LHC has so far cost US$9.2 billion to build, including the latest upgrades: version three comes with more data, better detectors and innovative ways to search for new physics. What’s more, scientists start with a tantalizing shopping list of anomalous results — many more than at the start of the last run — that hint at where to look for particles outside the standard model.

“We’re really starting with adrenaline up,” says Isabel Pedraza, a particle physicist at the Meritorious Autonomous University of Puebla (BUAP) in Mexico. “I’m sure we will see something in run 3.”

The true causes, to a physicist, are the fundamental forces acting between particles; all effects ripple out from there. Indeed, these forces, when they can be isolated, appear perfectly deterministic and reliable — physicists can predict with high precision the outcomes of particle collisions at the Large Hadron Collider, for instance. In this view, causes and effects become hard to predict from first principles only when there are too many variables to track.

Furthermore, philosophers have argued that causal power existing at two scales at once would be twice what the world needs; to avoid double-counting, the “exclusion argument” says all causal power must originate at the micro level. But it’s almost always easier to discuss causes and effects in terms of macroscopic entities. When we look for the cause of a fatal car crash, or Romeo’s decision to start climbing, “it doesn’t seem right to go all the way down to microscopic scales of neurons firing,” DeDeo said. “That’s where Erik [Hoel] is jumping in. It’s a bit of a bold thing to do to talk about the mathematics of causation.”

Other things to look forward to in Run 3 include the operation of two new experiments, FASER and SND@LHC, designed to look for physics beyond the Standard Model; special proton–helium collisions to measure how often the antimatter counterparts of protons are produced in these collisions; and collisions involving oxygen ions that will improve physicists’ knowledge of cosmic-ray physics and the quark–gluon plasma, a state of matter that existed shortly after the Big Bang.

Scientists just outside Chicago have found that the mass of a sub-atomic particle is not what it should be. The measurement is the first conclusive experimental result that is at odds one of the most important and successful theories of modern physics.

The team has found that the particle, known as a W boson, is more massive than the theories predicted.

So I modified the file /usr/lib/systemd/system/boinc-client.service and uncommented this line in the [Service] section:

PrivateTmp=true

I played around with WSL2 BOINC configurations, to be able to control it from Windows BOINC Manager and it doesn't seem to work cleanly. Configurations seem to be crisis-crossing somehow, WSL2 BOINC data directory seems to be getting changed or duplicated (still not sure which happens). Proxy settings on one affect the other. I'm still not all clear on what's going on but it doesn't seem to function like I expected, where you can manage both independently without one affecting the other. Unlike you, I don't have anything else connected, so I can see how your set up can get even more complicated. Do you have your BOINC clients set up to listen to different ports? That's what I had to do to prevent a problem in the last post. I changed the WSL2 one as it was easier but that made managing it through command line more difficult.
