This should reduce the configuration complexity by using the same code on all platforms. + * new xbt_cfg_elm_boolean type + * Allow to disable simgrid cleanups at exit from command line option. + There are situations where one may want a simulation to end with an exit. + Unfortunately, calling exit may cause SimGrid to segfault, which is quite + annoying when scripting around the simulator. Adding a + --cfg=clean_atexit:yes allows to circumvent this issue. Java: * Reintegrate Java to the main archive as desynchronizing these package is not acceptable anymore (Java is now considered stable) + * Add explicit synchronization facilities through semaphores * Bugfix: Task.setDataSize() only changed the C world, not the value cached in the Java world + MSG: + * Dramatically change the way files are handled. API and internals changed, but + this part of MSG was not considered as production grade either. + * Add explicit synchronization facilities through semaphores + * Add a new function MSG_host_get_process_list() + SMPI: + * SMPI is now included directly in the libsimgrid as the windows + linker dont forces us on splitting it anymore. * Improvements of the SMPI replay tool: - Most of the collective communications are now rooted in the same process as in the original application. - - Traces now rely on the same MPI datatype as the application (MPI_BYTE was + - Traces now rely on the same MPI datatype as the application (MPI_BYTE was used until now).
