Decision-first: On a GB10, pick low-active MoE models (A3B-class), serve GGUF (not MLX) via LM Studio, run one model at a time behind an OOM guard, and monitor GPU via DCGM but read the model footprint from system RAM (no framebuffer metrics). Dense 70B is unusable (~2-3 tok/s).

Scope & freshness: GB10 / Grace-Blackwell, 128 GB unified, DCGM 4.5.3 + driver 580-class, as of 2026-05-25. Re-check the DCGM profiling/framebuffer gaps after a driver/DCGM bump (≥585).

SSH Key Management#

SSH keys replace password authentication with cryptographic key pairs. The choice of algorithm matters:

Ed25519 (recommended): Based on elliptic curve cryptography. Produces small keys (256 bits) that are faster and more secure than RSA. Supported by OpenSSH 6.5+ (2014) – virtually all modern systems.

ssh-keygen -t ed25519 -C "user@hostname"

RSA 4096 (legacy compatibility): Use only when connecting to systems that do not support Ed25519. Always use 4096 bits – the default 3072 is adequate but 4096 provides a safety margin.
