QuakeTM is the first complex, real world application that was parallelized from sequential version using transactional memory.

QuakeTM is a parallel version of Quakeworld server application (a multiplayer version of the Quake game server) . It is parallelized from the sequential version using OpenMP and transactional memory.

QuakeTM consist of three applications:

  • the transactional server
  • the TraceBot client, for running traces
  • the VideoClient client, for visual testing and production of traces

The behavior of the server can be controlled by changing the macro definitions. It can be run in a serial, lock based or transactional version. It also supports two synchronization granularities: coarse-grained and fine-grained. Transactional nesting can be controlled by macros or it can be handled by the TM runtime system. Using macros, it is also easy to adopt the code to any TM implementation.

Currently the code is written to support the prototype version of the Intel STM compiler 3.0. The parallelization is done using OpenMP.
