Parallel Execution Visualized
Spawned at origin. Traversing the left corridor of the execution graph. Processing sequential memory reads with prefetch optimization. Page table entries cached.
Central path execution. Handling I/O-bound operations with async event loop processing. Awaiting resource acquisition from shared memory pool. Non-blocking poll active.
Right corridor. Compute-bound workload with heavy arithmetic operations. Near completion of assigned task partition. SIMD vectorization active on pipeline stage.
Requesting 4KB page from kernel. Virtual address mapping in progress. TLB cache miss handled via page walk. Buddy allocator searching free list.
malloc() -> mmap()
page_fault_handler()
buddy_alloc(order=0)
Socket read pending. Non-blocking poll on file descriptor. Epoll event loop cycling at 10ms intervals. Awaiting TCP ACK from remote peer.
epoll_wait(fd=7, timeout=10)
tcp_rcv_state_process()
sk_wait_data()
Matrix multiplication stage 3 of 5. SIMD vectorized path active. L2 cache utilization at 87%. Branch predictor accuracy 99.2%.
matmul_avx2(A, B, C)
_mm256_fmadd_ps()
cache_prefetch(L2)
MESI protocol state transition: Modified -> Shared. Broadcasting invalidation to sibling cores. Write-back buffer flushing 64-byte cache lines.
SIGUSR1 received. Entering signal handler context. Saving register state to signal frame. Executing deferred signal-safe operations.
Time quantum expired. Context switch initiated. Saving FPU/SSE state. Loading next task from run queue. CFS vruntime rebalancing across cores.
Mutex acquired. Critical section entered.
Hold time: 4.2ms · Lock addr: 0xFFAA0010
Spin-waiting for lock release. Backoff: exponential.
Spin count: 1024 · Wait time: 2.8ms
Blocked. Moved to wait queue. Priority inversion detected.
Queue depth: 2 · Wait time: 5.1ms
All execution paths have converged. Results aggregated across shared memory. State consistent. Lock-free data structures validated. The concurrent quest is complete.
