Deploying the memory-aware placement showed node01 to node04 reporting 7G
and node05 reporting nothing, on a machine whose /proc/meminfo plainly says
32 GB. node05 has no nvidia-smi, so GPU discovery returns an error, Discover
returns with it, and the memory read — which has nothing to do with cards —
never happened.
That is the node whose memory matters most, because a CPU profile is what a
GPU-less node will be asked to run, and min_memory_gb would have excluded it
from everything.
Read first now, before any path that can return early. The test fails
against the old order.
