DGX Spark memory management challenges detailed for LLM serving

By PulseAugur Editorial · [2 sources] ·

The DGX Spark, a system featuring the NVIDIA GB10 Grace Blackwell Superchip, offers approximately 115 GiB of usable memory for LLM serving after accounting for system processes and CUDA allocations. However, managing this shared memory pool is critical, as driver allocations can exceed process-level cgroup limits, potentially leading to system freezes and automatic restart loops. Strategies to mitigate these issues include careful monitoring of memory usage, disabling or shrinking swap space, and implementing specific commands to update container restart policies before rebooting.

    DGX Spark (GB10) memory sizing for LLM serving: the numbers

    <p>121.7 GiB is the Linux <code>MemTotal</code> we measured on one DGX Spark. The CUDA view on the same GB10 node reported 119.7 GiB. A sampler observed about 5.5 GiB in use with a Ray head and one GPU process running. For capacity planning, I use the lower CUDA total and round t…
