@firstadopter I heard the first person was there at 2:30 am :)

Guy said there are people lining up at 4AM to buy the limited inventory of RTX 5090s available for sale each day at GTC. lol

@PNY_Pro @NVIDIAGTC @nvidia great talking to you at the booth!

Introducing PNY's Token to Innovation Giveaway✨ In celebration of @NVIDIAGTC, we're giving 3 lucky professionals a chance to win an @NVIDIA DGX Spark. Stop by PNY Booth #1321 at the upcoming event to learn more, and find out how you can enter to win. We'll see you there 😉 #PNY #PNYPRO #NVIDIAGTC

@TheAhmadOsman I would say 3090 Ti for (3) - The original 3090's RAM chip placement can lead to overheating - it was fixed in the 3090Ti

If you’re asking what to buy, my recommendation based on the budget: 1. RTX PRO 6000 2. RTX 5090 3. RTX 3090 (used, from r/HardwareSwap)

@mvapich is at @NVIDIAGTC 2026 with posters focusing on #LLM inference, enhanced #GPU-Aware #MPI optimizations, and Vision #AI models. Major congratulations to our PhD Student Chen-Chun Chen for being nominated as one of the best poster finalists at #NVIDIAGTC this year!

@digitalix I just wonder/hope if there will be a refresh of it with much higher memory bandwidth - for our HPC codes, the memory bandwidth is too low to make sense for the cost

what do you want to know about the DGX Spark that might still be unknown? Like, are there features that you thought it has, but not sure. What questions do you want answered? I’m especially looking for questions about real performance, clustering, model support, software, and whether this makes sense vs a traditional GPU setup. Drop them below.

Attending the Solar Orbiter workshop? Don't miss our talks! 3/17 @ 10:05: "Comparison of Predicted Solar Polar Fields with Solar Orbiter Observations" (Jon Linker, C. Downs, R. Caplan, J. Turtle, P. Riley, G. Valori, Solar Orbiter PHI Team) buff.ly/AJIjRMe

🚨 New paper alert! 🚨 Yuan-Kuen Ko and co-authors (including PSI's Pete Riley and Roberto Lionello) deep dive into two coronal holes to present evidence for a surprisingly thick coronal hole boundary, and its implications for the "slow" solar wind. buff.ly/J7vBHYG

Just completed the Google for Developers "Intro to Inference: How to Run AI Models on a GPU" (developers.google.com/learn/pathways…) and it was my first experience running AI inference! I learned a lot! #NVIDIAGTC

@__tinygrad__ Some kind of supped up raspberry pi style tiny pc?

We are going to ship our first mass affordable product this year. Tentative price: $199. Who can guess what it is?

This week, we're showcasing another component of our in-house -- but open source -- suite of modeling tools...the Solar Wind Generator (SWiG)! If you need to rapidly generate WSA-like solar wind outputs, SWiG is a must-have. buff.ly/27eESkx

In @carolinevans04, Cooper Downs, and Don Schmit's new #ApJ paper, a series of simulations at increasing resolution uncover the correlation between magnetic complexity and coronal heating. The MAS model acted as a lab to probe difficult-to-observe scales. buff.ly/ls2p29Z
