Current tour TOC: + # Lesson 0: Installing GRAS + # Lesson 1: Setting up your own project + # Lesson 2: Exchanging simple messages + # Lesson 3: Passing arguments to the processes (in SG) + # Lesson 4: Attaching callbacks to messages + # Lesson 5: Using globals in processes + # Lesson 6: Logging informations properly + # Lesson 7: Using internal timers + # Lesson 8: Handling errors through exceptions + More a due, of course. At least the one explaining how to add data + into messages. In the meanwhile, you can check the examples which are + still here. + + -- + +SimGrid (3.1) unstable; urgency=low + + General: + * Port to gcc 4.x + There was a stack corruption somewhere, visible only when optimizing + with these versions. [Vince] + + SIMDAG: + * This is a NEW module! SimDAG (SD for short) is a revival of the old SG + module that enabled to play with Directed Acyclic Graphs. It is built + directly on top of SURF and provides an API rather close to the old + SG. Some old codes using SG are currently under rewrite to check that + all needful functions are provided. [Christophe Thiery] + + SURF: + * Complete rewrite of the KCCFLN05 workstation model. It is now an + extension of the classical CLM03 model that gracefully handles + failures. This is now the default model for MSG and GRAS. It doesn't + handle parallel tasks yet though. [AL] + * Bug fix: Weights were not correctly set in the network part. + WARNING: This may have resulted in incorrect results with simulations + where there are more than one flow on a given link. [AL] + + SURF, MSG, GRAS: + * After a (long ?) discussion on simgrid-devel, we have decided that the + convention we had on units was stupid. That is why it has been decided + to move from (MBits, MFlops, seconds) to (Bits, Flops, seconds). + WARNING : This means that all previous platform files will not work as + such with this version! A warning is issued to ask users to update + their files. [AL] + A conversion script can be found in the contrib module of the CVS, under + the name contrib/platform_generation/surfxml_update.pl [MQ] + + MSG,GRAS: + * Bug fix: Processes were started in reverse order, wrt deployment file. + WARNING: if your code relies on this bug, please fix it. [AL] + * Bug fix: Add a test in MSG_task_execute to stop whenever a task is + being executed on two different locations. [AL] + * Bug fix: Failures are now better supported thanks to Derrick's tests + (there was many failure situations I hadn't thought of and that weren't + correctly handled). [AL] + * New function: MSG_host_is_avail indicates you whether a given m_host_t + is up or down. [AL] + + GRAS: + * New! a real RPC mecanism, as it ought to be since too long. [MQ] + Exception occurring on server-side are propagated back to client (!). + + API CHANGE: the callback changed their prototype. Change: + int my_handler(gras_socket_t expeditor, void *payload_data) { + to: + int my_handler(gras_msg_cb_ctx_t ctx , void *payload_data) { + gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx); + and you're set. + * New! function: gras_msg_handleall to deal with all messages arriving + within a given period. + * New! function: gras_socket_server_range to get a server socket in a + range of port numbers (ease to avoid port number conflicts) [MQ] + * New! gras processes display their backtrace when they get a SIGUSR1 + or when Ctrl-C is pressed. Use Ctrl-C Ctrl-C to exit. + Sweet to debug RL processes [MQ] + + AMOK: + * Bandwidth module: + - Do not force experiment sizes to be expressed in kb, or it becomes + impossible to measure the latency this way (needs one byte-long tests) + WARNING: this changes the amok_bw_* function semantic. [MQ] + - Implements the link saturation stuff. [MQ] + * Peer management module: + New! module factorizing code that we wrote over and over [MQ]. + + XBT: + * New module: cunit (my jUnit implementation in ansi C) [MQ] + - Test units are placed directly into the library code, they get extracted + automatically and placed into the src/testall binary. + - Convert most of the XBT tests to this system. + * New functions: xbt_dynar_getfirst_as() and xbt_dynar_getlast_as() [MQ] + * XML parsing: rewrote parts of flexml to enable multiple xml parsers to + live in the same C code. This required to change a little bit the API + of surfxml parsing but shouldn't be an issue for end-users. [AL] + * New module: sparse graph structure with basic algorithms (this is work + in progress and the API is not considered to be frozen yet). [AL] + * Display more information on backtraces: source line & function names are + now displayed just like valgrind does (rely on addr2line tool) [MQ] + * New function: xbt_backtrace_display(). Sweet while debuging [MQ] + * Reworked a little bit some #include statements to load only required + headers. Some user code that relied on SimGrid to include stdlib or + stdio may need to include it by themselves. [AL] + * Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with + g++. [AL] + * Renamed xbt_host_t into xbt_peer_t since it betterly describes what I + meant. This breaks the API of AMOK and of xbt/config. Sorry about this, + but I guess that almost nobody used those parts.
