Simulator knobs.

Fields

drive: DriveModel

The drive.

pool_pages: u32

Pages in the region pool.

lead_radius: u32

Regions within this walk distance of the player are requested (lead ring), nearest first.

keep_radius: u32

Unwanted regions within this distance are in the hysteresis band.

speed_units_per_second: u32

Player speed assumed for lead deadlines, units per second. The default is the design’s v_max of 470, a design estimate, not a measurement.

max_in_flight: u8

Transport depth.

tick_micros: u32

Microseconds per simulated tick (16 667: 60 Hz).

install_ticks: u32

Ticks of install work after a region lands (0: none, the region is resident when read). The design lists the install cost as unmeasured.

fail_every: u32

Every Nth read fails (0: none).

placement: Placement

Placement policy of the pool.

movable: bool

Whether compaction may move regions.

step_budget: u32

Bookkeeping budget per step, passed on as the step_budget of the [psx_residency::Config].

pinned: Vec<u32>

Regions pinned for the whole run (the home pin), at demand class.

warm_start: bool

Load the start region’s needs before the route begins (a loading screen at boot), not counted in the report.

Implementations

impl SimConfig

pub fn new(pool_pages: u32, lead_radius: u32) -> Self

Defaults: double-speed nominal drive, queue depth 2, 60 Hz ticks, no install cost, no failures, best-fit, movable, warm start, keep radius one quarter beyond the lead radius.

Trait Implementations

impl Clone for SimConfig

fn clone(&self) -> SimConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SimConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
