A C library for using the perf API on Linux

COUNTDOWN is a tool for identifying and automatically reducing the power consumption of the computing elements during MPI communications.

Provides access to the performance monitoring counters exposed by the Linux perf_events kernel API.

Membench - Memory Microbenchmark

In this repo, we provide different labs and related tutorials regarding OS tracing.

Course done at IISc under Professors: Govindarajan, Arkaprava Basu

High-performance kernel & assembly debugging toolkit: demos for CPU affinity, NUMA, lock-free, cacheline, and memory bank conflicts. GDB, perf, bpftrace, Rust/C, reproducible root cause analysis.

Creates bundles of VM related hardware trace packets in JSON

Real-time Linux perf profiling streamed to your browser. Remote agent captures perf record+stat from any ARM/x86 device, streams it over a zstd-framed TCP link, and a stdlib-only Python server renders live flame graphs, function tables, and addr2line-annotated source.

Objective: To find the bottlenecks in the unoptimized single-threaded program for Checkered Matrix Multiplication using PMCs through perf and implemented the optimized single-threaded, multi-threaded and GPU program using CUDA for the same.

libperf is a library that wraps around the `perf_event_open()` syscall, to expose the Linux kernel performance counters subsystem to userspace.
