loadable kernel module for Linux 2.4.x and 2.6.x kernels on the x86, x86_64, PPC/PPC64, ARM architectures, and a
small LGPL-licensed library.
== PinLIT / PinPlay ==
PinLIT (Pin-Long Instruction Trace) is a checkpointing tool built on top of Intel's proprietary [ PIN binary instrumentation tool] described on page 48 of [ Cristiano Pereira's PhD thesis]. It records the processor's (big) architectural register state and all pages of memory that contain application and shared library code, optimizing size by only storing memory used during a desired interval.
[ PinPlay] or the Program Record/Replay Toolkit appears to be the successor of or new name for PinLIT.
Both tools appear primarily focused on reducing benchmark runtime on slow computer architecture simulators, leveraging sampling algorithms such as SimPoint.
