The Perlmutters visit @NERSC's Perlmutter supercomputer!

It was an honor to show the Perlmutter family around our machine room this morning & introduce them to all of the great science their namesake system supports.

I won a thing one time. Perhaps you know someone else who should win it too! If so, please nominate them by December 31st!

[NERSC @NERSC]

Congrats again to NERSC's own @hpcgal , who set the bar high for winners of the Krell Institute's James Corones Award. Do you know the next honoree—a mid-career scientist impacting their field? Nominations are due 12/31! See below for details.

@astrotoya Possibly teething? They definitely can have regressions like this, it's perfectly normal. Hopefully he gets back to his old habits soon.

Y'all, I'm hiring for a Science Engagement Engineer @NERSC. Help us build a user community of practice, in which #HPC users interact to share best practices & improve their skills! Remote friendly, US citizenship not required. https://t.co/rCIfxdvIOV

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

Y'all, I'm hiring for an #HPC consultant position @NERSC. If you like helping users of HPC resources use them even better & want to bring science solutions to the world, this is a good job for you! US citizenship NOT required, remote friendly. More info: https://t.co/oE0RfRzzf4

@dahong_li Thank you for all your hard work in making MANA usable!

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

There was a Livestream error at first, but SuperCheck-SC22 is off to a good start. More than 40 people in person. Currently, invited speaker Johann Lombardi is speaking about DAOS. Unfortunately, I arrived in the middle of his talk (due to aforementioned Livestream glitch)

[NERSC @NERSC]

When it comes to fault-tolerant computing, checkpoint/restart has become a critical tool for #HPC. Learn more about ongoing R&D advances at today’s SuperCheck #SC22 Symposium, 8:30-12 CST, C143-149 https://t.co/5eXit5f2U8

@PawseyCentre End of an era! 😢

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

This made me literally LOL 😆🤣

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

Today at 12:15 @Supercomputing , we are holding a #BOF on our proposed standard for checkpoint/restart! Please join us in C141-143-149 to learn about CRI v 1.0.

If you're not at #SC22 in person & want to see the standard let me know & I'll get it to you.

A member of my group is also using this so both spouses are able to travel at the same time! Back in the day when my husband came along to help me with signage at the conference, we left our son with my parents. We might have brought him along if this had been available then!

[Nalini Kumar (she/her) @NaliniK06051863]

Huge shout out to @Supercomputing organizers and the #SC22 inclusivity chair for providing on-site child care. It's a great resource which allows me to be a parent and a passionate HPC practitioner at the same time!

[Dr. Hai Ah Nam @DrHaiAhNam]

So excited at #SC22 to see which team will win the @SCCompSC.

Teams are working hard benchmarking #HPL #HPCG #IO500 #AI before the application workload kick off at the gala tonight.

Thanks @MLPerf @MLCommons @grigori_fursin @OctoML for the #AI benchmark.

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

That was it! Thanks everybody for a successful workshop. Cool talks!

[Dr. Rebecca Hartman-Baker @[email protected] @hpcgal]

Future work: get working on Perlmutter, support dynamic linking of lower half in MANA (will be a big part of it), improve testing/debugging capabilities.
