Either use git-archive to - generate the tarball, or keep using cmake -E tar, but use git-ls-files - to get the list of files to pack. - - For Java, add an option to enable/disable the inclusion of the native - libraries in the jar file, and avoid to duplicate these files. - - TOOLS: +SimGrid (3.12) NOT RELEASED; urgency=low + + cMSG: + * Interface improvement: + - Rename MSG_host_is_avail(h) to MSG_host_is_on(h) + - Sanitize the interface in MSG_task_ module: + - Merge two functions that were close enough but misleading: + set_compute_duration(t) -> set_flops_amount(t) + get_remaining_computation(t) -> set_flops_amount(t) + - set_data_size(t) -> set_bytes_amount(t) + get_data_size(t) -> get_bytes_amount(t) + - Massive cleanups in the functions related to the energy + - MSG_host_get_pstate_number() -> MSG_host_get_nb_pstates() + - New: MSG_host_get_pstate() + * New example: + - msg/energy/onoff: switching hosts on and off + jMSG: + * Interface improvement: + - Rename Host.isAvail() to Host.isOn() + - Rename Process.currentProcess() to Process.getCurrentProcess() + - Rename Task.setDataSize() to Task.setBytesAmount() + - Merge Task.getRemainingDuration() and Task.getComputeDuration() into Task.getFlopsAmount() + * Bug fixes: + - #18874: Actually allows the GC to reclaim tasks + + SIMIX: + * New functions + - SIMIX_process_throw: raises an exception in a remote process + * Refactoring: Separate submodules + - libsmx: the public interface, as libc in a real system + - popping: the strange dance that converts a user request into a kernel handling + - smx_context_*: the virtualization mechanisms that embeed the user code + - smx_*: the handling of each simcalls + * Interface cleanup: + - simcall_host_set_power_peak_at -> simcall_host_set_pstate + * Rename smx_action_t into smx_synchro_t, making explicit that these + things are used to synchronize processes with their environment. + For example, a communication is a sort of synchronization involving + the communicating processes (that may block until the exchange) and + the platform.
