Usually 30-40k of that is me (big ooh), but with temps in the 90s and the PC in a no-AC room, I’m having to shut things down during the hottest part of the day.
Every work unit counts @NoFumus, but you are right about the heat. Folding can make more of it LOL. We’re in the 80’s and 90’s, and I think I heard rumors of a “heat wave”, but hard to tell, as everything is being hyped these days.

Not sure it’s the work units - it might be the algorithm or some calculation that fails for some reason - the error being “particle coordinate is nan” (not-a-number)
Well @daath (and ELR Team), it appears they sorted out those bad work units, but looking like we ran outta work units all together again. I noticed the office wasn’t “warm” LOL, and …

One million volunteers and more than 2.5 exaFLOPS later, the group behind the crowdsourced distributed-computing project says it has found possible targets for stopping the SARS-CoV-2 virus.
In its SARS-CoV-2 simulations, F@h first targeted the spike, the cone-shaped appendages on the surface of the virus consisting of three proteins. The spike must open to attach itself to a human cell to infiltrate and replicate. F@h’s mission was to simulate this opening process to gain unique insight into what the open state looks like and find a way to inhibit the connection between the spike and human cells.
And it did so. In a newly published paper, the Folding@home team said it was able to simulate an “unprecedented” 0.1 seconds of the viral proteome. They captured dramatic opening of the spike complex, as well as shape-shifting in other proteins that revealed more than 50 “cryptic” pockets that expand targeting options for the design of antivirals.
SARS-CoV-2 has intricate mechanisms for initiating infection, immune evasion/suppression, and replication, which depend on the structure and dynamics of its constituent proteins. Many protein structures have been solved, but far less is known about their relevant conformational changes. To address this challenge, over a million citizen scientists banded together through the Folding@home distributed computing project to create the first exascale computer and simulate an unprecedented 0.1 seconds of the viral proteome. Our simulations capture dramatic opening of the apo Spike complex, far beyond that seen experimentally, which explains and successfully predicts the existence of “cryptic” epitopes. Different Spike homologues modulate the probabilities of open versus closed structures, balancing receptor binding and immune evasion. We also observe dramatic conformational changes across the proteome, which reveal over 50 “cryptic” pockets that expand targeting options for the design of antivirals. All data and models are freely available online, providing a quantitative structural atlas.
