As the progress in transistor scaling slows down, low-level performance tuning becomes an important tool to accelerate compute-intensive codes. However, the community of experts who could optimize the codes on low-level is tiny, and their ability to contribute optimizations to open-source software is often restricted by lack of access to relevant hardware. We present PeachPy.io, and IDE for low-level performance tuning that works inside a Web browser. On PeachPy.io developers can modify assembly kernels, run them on different hardware platforms, analyze performance bottlenecks through hardware performance counters, and compare against alternatives without any time-consuming client-side configuration. PeachPy.io crowd-sources performance tuning, and lets anyone interested try their skills in low-level optimization without spending time on local software configuration or investing financial resources to acquire hardware.
