Idea for demo: best practices for debugging single locale Chapel programs

[dutta-alankar]

I was wondering if these sessions are recorded. Then, it would give me an idea of the format of the meeting and what to expect as a newcomer.

[agirish]

Yes, demo sessions are usually recorded and land on our YouTube page: https://www.youtube.com/c/ChapelParallelProgrammingLanguage

Please review the recent videos and let us know if you have any more questions. You’ll see that the format is generally quite relaxed. If there’s a topic you’d like to discuss in depth or demo, please share it here. We can discuss further and schedule a date that suits you.

[bradcray]

Hi @dutta-alankar : Tagging onto Abhishek's response, though we record demos that we think will be valuable to the community, we don't record and archive all instances of this meeting. E.g., if we were doing an interactive code review or pair-programming, we probably would not record it unless all participants wanted that.

[singhalshubh]

Hi everyone,
I am Shubhendra Pal Singhal, third year PhD student working under Dr. Vivek Sarkar at Habanero Labs. We have been in talks with Dr. Brad and Dr. Engin and they both recommended us to present our work here. We investigated performance results for Index Gather application on Frontier at ORNL for Conveyors (bale) and Chapel. We work in improving Conveyors and supporting graph applications using aggregation as a policy. I would like to propose an idea for our presentation sometime to present our results and get feedback on measurements and of any potential future research improvements. Please let us know which date suits the best. I will be the one presenting our slides and folks from Georgia Tech - Dr. Akihiro Hayashi, Dr. Vivek Sarkar and ORNL - Dr. Oscar Hernandez and Dr. Aaron Welch shall join the meeting as well. Looking forward to hearing from you all!
Thank you
Shubhendra Pal Singhal (Shubh)

[agirish]

Perfect, thanks for confirming Shubh. If anything changes, we'll certainly keep you posted. We'll announce this to the community a few days before the meeting. We're excited & looking forward to meeting you all as well.

[singhalshubh]

Sounds wonderful. Thank you and looking forward to meeting you all.

[singhalshubh]

Hi @agirish ,
Just wanted to confirm, our slot is on Sept 25th, since I see the scheduled slot on top of the page as 26th. Please let me know. Thanks

[agirish]

@singhalshubh It is Thursday, Sep 25th at 10 AM Pacific. Thanks for catching the typo on top of the page. I've fixed it.

[singhalshubh]

Thank you for confirming! Sounds good.

[bradcray]

I'd like to reserve the Sept 18 date for the next TSC meeting if that would be OK.

[agirish]

Sounds good. I'll update the list above - and also rename the calendar instance for the 18th (and for the one prior)

[bradcray]

@agirish: Can I reserve the Thursday, Oct 2 slot for the next TSC meeting?

[agirish]

Of course. I'll add it to the Scheduled meetings list above. And update the instance for Oct 2.

[bradcray]

We should take Oct 9 off for ChapelCon. :)

[@Agrish: I re-arranged the categories in the OP to have the upcoming meetings first since the completed meetings list will only get longer over time and push the more interesting/useful stuff further down]

[agirish]

Makes sense. I did remove the calendar entry for October 9.

[bradcray]

I'd like to reserve Oct 23 for our next TSC meeting if it's not already spoken for.

[markthitrin]

Hi everyone,
My name is Thitrin Sastarasadhit. I’d like to present my work on implementing transformers in Chapel at the upcoming Thursday meeting, if there’s time available.

I have implemented the model from scratch and conducted some performance experiments. I’d like to share the results and receive feedback on my measurement methods and findings.

[agirish]

@markthitrin, nice to virtually meet you! I've scheduled you for our meeting this Thursday, Nov 6 at 10 AM Pacific. We look forward to meeting you.

[markthitrin]

Thank you very much!

[agirish]

@markthitrin heard about the Teams issue. We recently updated our Calendar invites but this GitHub Discussion had the previous link, causing the issue. Apologies for the mixup, but glad you were able to join eventually. I've fixed this now - so future meetings shouldn't have this problem for anyone.

[singhalshubh]

Hi everyone,
Can I please ask for a slot for my second presentation on Chapel and Conveyors IG? I have some data points to discuss which should be interesting to discuss and present. Thank you!

[agirish]

@singhalshubh , sure! Tomorrow would be too short a notice for everyone to join. Next Thursday is Thanksgiving. So the soonest we can target this is Dec 4. If that works for you, I can double check availability and schedule it.

[singhalshubh]

Definitely. I will be able to join Dec 4th. Thank you so much for your prompt reply.
