Thunder Nodes (ARM) — Let Us Know If You Use Them: Our ARM-based Thunder nodes at NCAR are currently in maintenance and may be removed from Chameleon service in the near future due to low utilization. If your research depends on these nodes, please reach out to us with a comment below or reach out directly to our project manager, Marc Richardson (mtrichardson@uchicago.edu) by the end of May 2026.
