Dynamic resource management in HPC is promising, but it only matters if it works under realistic supercomputer conditions.

If you care about practical dynamic resource management in HPC (not just theory), this oneโ€™s for you ๐Ÿ˜Š

In some cases, the LLM may perform better (especially when you are assigned a paper outside your main area of expertise). However, LLM's recommendations often tend to lean towards "accept with minor revisions".

I've always wished, and asked, to have screen monitors for the panelists or BoF speakers. So you can see the presentation of your partners and have a better understanding of the afterward discussions with the audience. Regrettably, it has never been implemented โ˜น๏ธ Hope you could do something ๐Ÿคฉ
