Rcore Gangs Fix 【2025-2026】
It sounds like you're referring to (the educational OS kernel written in Rust, often used in Tsinghua University’s OS courses) and gangs in the context of parallel computing or OS process groups (e.g., gang scheduling).
fn next(&mut self) -> Option<Arc<TaskControlBlock>> if let Some(tid) = self.gang_sched.pick_next_task() return find_task_by_tid(tid); self.inner.next() rcore gangs
impl Scheduler for HybridScheduler fn push(&mut self, task: Arc<TaskControlBlock>) if let Some(gang_id) = self.gang_sched.task_to_gang.get(&task.tid) self.gang_sched.notify_task_ready(task.tid); else self.inner.push(task); It sounds like you're referring to (the educational
#[derive(PartialEq)] pub enum GangStatus Pending, // waiting for all members to be ready Runnable, // all ready, can schedule Running, // currently scheduled on CPUs gang scheduling). fn next(&mut self) ->
pub struct GangScheduler gangs: BTreeMap<usize, Arc<Mutex<Gang>>>, task_to_gang: BTreeMap<usize, usize>, ready_gangs: VecDeque<usize>, // queue of gang IDs ready to run
