DGX Spark week-one tests expose rough edges

A LocalLLaMA user shared an early hands-on report after building a gateway and load-balanced workload setup across DGX Spark units. They report acceptable CPU/GPU behavior and low power usage, but significant friction from ARM compatibility, missing Python wheels, source builds, unified-memory limits, and no MIG support.

// ANALYSIS

DGX Spark looks promising for compact local AI infrastructure, but today it still demands operator patience and Linux-level troubleshooting.

–Power efficiency and baseline compute seem good enough for always-on local inference experiments.
–Toolchain maturity is the bottleneck: dependency conflicts and missing ARM wheels slow iteration more than raw hardware limits.
–Lack of MIG and tight unified-memory management make multi-tenant or mixed-workload scheduling harder than on datacenter GPUs.
