back to article Open source at America's famous Los Alamos Lab: Pragmatism as its nucleus

Established 80 years ago this year, Los Alamos National Labs remains most famous for its central role in developing the first atomic bomb. But that belies the breadth of scientific research it has undertaken since, encompassing physics, chemistry and biology, and addressing the threat of COVID-19. Despite the breadth of …

    The backend database on an HPC system is to store the model configuration, so you need ease of use and quick snapshots more than you need complex custom SQL triggers and report generation

    Good enough for Los Alamos?

    Good enough for me.

    Do they use OpenZFS to store their data, just like their cousin, the Lawrence Livermore National Laboratory?

    Not going to throw stones, I'm running 10.3 in production, the Enterprise branch for which 10.6 is still the most recent. Upgrading is on the way, but needs to be done with zero downtime, so quite carefully. I really like MariaDB and their support team.

    Engineers and wonderfully practical

    “Being able to burst into the cloud is wonderful, but don't neglect the core engine in your car...." Words of wisdom in today's "where's my data?" -- or -- "the cloud is down?" world.

      But... But... The cloud can't possibly be down. They promised.

    "It might surprise some, then, that the 20,000-node cluster, dubbed Trinity, running on Cray hardware relies on an open-source community edition of MariaDB"

    Good, and it sounds like they have permanently avoided the menacing clutches of Larry's Oracle.

    I'm not criticising here, just observing.

    Step 1. "The Department of Energy needs an HPC facility to simulate nuclear explosions and such."

    Step 2. Money is allocated, and the HPC is installed.

    Step 3. "This HPC thing works great, but we've got a lot of unused capacity here. It would make economic sense to run other scientists' workloads, too."

    Step 4. DoE HPC becomes wildly popular among scientists using it to run their jobs. Many scientists and organizations want to use it.

    Step 5. "This HPC thing still is working great, but we're uncomfortably-close to maxing it out. We need a faster HPC to cope with the workloads."

    Step 6. Go to step 2.

      Better mousetrap, and all that.

      Really, it's a "simple" (heh) demonstration of the idea that good quality and service attracts customers.

      Big dumb corporations try to replicate that success with the usual dirty tricks, e.g. vendor lock-in, monopoly strangleholds, anti-competitive behavior, overt and possibly deceptive marketing, and so on. Unfortunately the mania for short-term growth at all costs tends to reward their behavior.
