TinySTM is a lightweight but efficient word-based STM implementation. This distribution includes three versions of TinySTM: write-back (updates are buffered until commit time), write-through (updates are directly written to memory), and commit-time locking (locks are only acquired upon commit). The version can be selected by editing the makefile, which documents all the different compilation options.

TinySTM compiles and runs on 32 or 64-bit architectures. It was tested on various flavors of Unix, on Mac OS X, and on Windows using cygwin. It comes with a few test applications, notably a linked list, a skip list, and a red-black tree.

TinySTM requires the 'atomic_ops' library, freely available from www.hpl.hp.com. A stripped-down version of the library is included in the TinySTM distribution. If you wish to use another version, you must set the environment variable LIBAO_HOME to the installation directory of 'atomic_ops'.

If your system does not support GCC thread-local storage, modify the TLS parameter in the 'Makefile' file.

To compile TinySTM libraries, execute 'make' in the main directory. To compile test applications, execute 'make test'. To check the compiled library, execute 'make check'. 'make clean' will remove all compiled files. To compile the TinySTM GCC compatible library, execute 'make abi-gcc'. To compile test applications, execute 'make abi-gcc-test'.
