It is very +handy when you want to test an algorithm or protocol that only react +to external events. For example, many P2P protocols react to user +requests, but do nothing if there is no such event. + +In such situations, you should write your protocol in C++, and separate +the workload that you want to play onto your protocol in a separate +text file. Declare a function handling each type of the events in your +trace, register them using @ref xbt_replay_action_register in your +main, and then run the simulation. + +Then, you can either have one trace file containing all your events, +or a file per simulated process: the former may be easier to work +with, but the second is more efficient on very large traces. Check +also the tesh files in the example directories for details. + + - Communication replay. + @ref examples/s4u/actions-comm/s4u_actions-comm.cpp \n + Presents a set of event handlers reproducing classical communication + primitives (asynchronous send/receive at the moment). + + - I/O replay. + @ref examples/s4u/actions-storage/s4u_actions-storage.cpp \n + Presents a set of event handlers reproducing classical I/O + primitives (open, read, close). + */ /** -@example examples/s4u/launching/s4u_launching.cpp +@example examples/s4u/actions-comm/s4u_actions-comm.cpp +@example examples/s4u/actions-storage/s4u_actions-storage.cpp +@example examples/s4u/actor-migration/s4u_actor-migration.cpp @example examples/s4u/app-token-ring/s4u_app-token-ring.cpp @example examples/s4u/app-master-worker/s4u_app-master-worker.cpp @example examples/s4u/launching/deployment.xml +@example examples/s4u/launching/s4u_launching.cpp @example examples/s4u/mutex/s4u_mutex.cpp */ \ No newline at end of file diff --git a/examples/s4u/actions-comm/s4u_actions-comm.cpp b/examples/s4u/actions-comm/s4u_actions-comm.cpp index 1cbdbfbaa2..44b42d1b8c 100644 --- a/examples/s4u/actions-comm/s4u_actions-comm.cpp +++ b/examples/s4u/actions-comm/s4u_actions-comm.cpp @@ -104,7 +104,6 @@ int main(int argc, char *argv[]) xbt_replay_action_register("send", Replayer::send); xbt_replay_action_register("recv", Replayer::recv); - /* Actually do the simulation using MSG_action_trace_run */ if (argv[3]) { simgrid::xbt::action_fs = new std::ifstream(argv[3], std::ifstream::in); } diff --git a/examples/s4u/actions-storage/s4u_actions-storage.cpp b/examples/s4u/actions-storage/s4u_actions-storage.cpp index 0c10dedde9..21f9e13952 100644 --- a/examples/s4u/actions-storage/s4u_actions-storage.cpp +++ b/examples/s4u/actions-storage/s4u_actions-storage.cpp @@ -120,7 +120,6 @@ int main(int argc, char* argv[]) xbt_replay_action_register("read", Replayer::read); xbt_replay_action_register("close", Replayer::close); - /* Actually do the simulation using MSG_action_trace_run */ if (argv[3]) { simgrid::xbt::action_fs = new std::ifstream(argv[3], std::ifstream::in); }
