spec property
Spec is the machine's static capability — os, arch, cores, RAM, accelerators. Every field is bounded on write and at most 32 accelerators are accepted, so what comes back may be clamped. Omit it for a destination nothing probes.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
