3The smallest mesh GPU program, for lifecycle tests: op 0 returns `arg * 3 + 7`. View: `0x0` magic
4"HELO" (set by init), `0x4` the last arg, `0x8` the last result. Counters: 0 tasks, 1 inits.

6A `ptx` package: `sexc build` compiles `src/hello.c` for nvptx64; `mesh-build-programs` links it into
7the catalog's `hello.ptx` in the cluster float mode.
