* Cross-platform process metrics support (#887)Stefan Boberg4 days1-4/+1
| | | | | | | - **Cross-platform `GetProcessMetrics`**: Implement Linux (`/proc/{pid}/stat`, `/proc/{pid}/statm`, `/proc/{pid}/status`) and macOS (`proc_pidinfo(PROC_PIDTASKINFO)`) support for CPU times and memory metrics. Fix Windows to populate the `MemoryBytes` field (was always 0). All platforms now set `MemoryBytes = WorkingSetSize`. - **`ProcessMetricsTracker`**: Experimental utility class (`zenutil`) that periodically samples resource usage for a set of tracked child processes. Supports both a dedicated background thread and an ASIO steady_timer mode. Computes delta-based CPU usage percentage across samples, with batched sampling (8 processes per tick) to limit per-cycle overhead. - **`ProcessHandle` documentation**: Add Doxygen comments to all public methods describing platform-specific behavior. - **Cleanup**: Remove unused `ZEN_RUN_TESTS` macro (inlined at its single call site in `zenserver/main.cpp`), remove dead `#if 0` thread-shutdown workaround block. - **Minor fixes**: Use `HttpClientAccessToken` constructor in hordeclient instead of setting private members directly. Log ASIO version at startup and include it in the server settings list.
* compute orchestration (#763)Stefan Boberg2026-03-041-0/+382
- Added local process runners for Linux/Wine, Mac with some sandboxing support - Horde & Nomad provisioning for development and testing - Client session queues with lifecycle management (active/draining/cancelled), automatic retry with configurable limits, and manual reschedule API - Improved web UI for orchestrator, compute, and hub dashboards with WebSocket push updates - Some security hardening - Improved scalability and `zen exec` command Still experimental - compute support is disabled by default
