Struct SystemMonitor 

pub struct SystemMonitor { /* private fields */ }

Real-time system monitor for GPU performance profiling

Tracks performance metrics over time with checkpoint-based profiling. Useful for debugging GPU operations and identifying performance bottlenecks.

Example

use volta::gpu::system_monitor::SystemMonitor;

let monitor = SystemMonitor::new();

monitor.checkpoint("setup_start");
// ... GPU operations ...
monitor.checkpoint("setup_complete");

// ... more operations ...

let stats = monitor.stats();
println!("Ops/sec: {:.2}", stats.ops_per_sec);

Implementations

impl SystemMonitor

pub fn new() -> Self

Create a new system monitor

pub fn checkpoint(&self, label: &str)

Record a checkpoint with a descriptive label

Prints performance metrics including memory usage, operation counts, operations per second, sync count, and pending GPU operations.

Arguments

• label - Descriptive name for this checkpoint

pub fn record_operation(&self)

Record a GPU operation

Increments the operation counter. Call this after each GPU operation to track total workload.

pub fn record_sync(&self)

Record a GPU sync

Increments the sync counter. Call this after each gpu_sync() call to track synchronization frequency.

pub fn stats(&self) -> MonitorStats

Get current performance statistics

Returns a snapshot of performance metrics including elapsed time, peak memory usage, operation counts, and throughput.

pub fn reset(&self)

Reset all counters and timers

Useful for starting fresh profiling sessions without creating a new monitor instance.

Trait Implementations

impl Default for SystemMonitor

fn default() -> Self

Returns the “default value” for a type.
