Revision Author Date Message Commit Date
832b6fc Pierre Schweitzer 26 September 2013, 12:23:04 UTC Simplify the call graph storage by removing redundant information 26 September 2013, 12:23:04 UTC
2b0d14e Pierre Schweitzer 23 September 2013, 13:18:15 UTC Add more build targets for easier comparisons 23 September 2013, 13:18:15 UTC
68cc9b7 Pierre Schweitzer 11 September 2013, 16:13:01 UTC Changed the way we handle multithreading. The previous way was wrong. Now, we ask the user to define when he wants multithreading support Added a semaphore to allow the new thread to signal when it's ready. This prevents mutex to be released too early and thus, prevents race conditions. Cut the advice around pthread_create in two (before/after), because the around advice appears to generate something wrong that G++ is unable to build. 11 September 2013, 16:13:01 UTC
0fa2a76 Pierre Schweitzer 11 September 2013, 13:06:06 UTC Fix the broken logic with multi-threading support. The previously generated call graph was just wrong, mixing all the data possible. Now, we generate a complete call graph, with all the correct data for each thread. Furthermore, we can now know which thread is called by whom. The drawback of such method is that it requires the user doesn't use pthread_create() anymore but TProfiler::pthread_create() so that we can weave on it. This function has the exact same prototype and behaviour than pthread_create() 11 September 2013, 13:06:06 UTC
55ed1ae Pierre Schweitzer 11 September 2013, 09:19:05 UTC Remove now useless variable (after: 1609e11bd555e819b6ce83530622198155fb15ae) 11 September 2013, 09:19:05 UTC
4f9ab96 Pierre Schweitzer 28 August 2013, 15:47:10 UTC Cosmetic code fix 28 August 2013, 15:47:10 UTC
bec8a70 Pierre Schweitzer 28 August 2013, 15:19:55 UTC Thanks to 500954476f5597681d983cd0abdfb6456ca8d317, this condition cannot be wrong anymore 28 August 2013, 15:19:55 UTC
1609e11 Pierre Schweitzer 28 August 2013, 15:15:54 UTC Take advantage of 5d5ee98d99a9ecf7d670412cc8a961693d1815da Our arrays size is now constant and we don't need to have algorithms that can adapt to its changing size. This helps simplifying the reduce operation at the end 28 August 2013, 15:15:54 UTC
9923c84 Pierre Schweitzer 28 August 2013, 14:06:32 UTC Take advantage of 500954476f5597681d983cd0abdfb6456ca8d317. As we limit usage of features, we can make assertions on their usage in code 28 August 2013, 14:06:32 UTC
5009544 Pierre Schweitzer 28 August 2013, 13:44:11 UTC Only enable the distribution features if we have enough cores on the machine (ie, more than 1) 28 August 2013, 13:44:11 UTC
5d5ee98 Pierre Schweitzer 28 August 2013, 13:34:00 UTC Quit using online processors count and move to configured processors count. It is the maximum processors count usuable, even if not online yet. It is set at boot time. It will help simplify the code 28 August 2013, 13:34:00 UTC
c2d3f80 Pierre Schweitzer 15 August 2013, 08:51:59 UTC Add support for multithreaded code profiling. So far profiler relies on a big lock to ensure that its data are not being overwritten while read. Code is not directly implemented in the aspect to prevent a superfluous lib pthread dependency. 15 August 2013, 08:51:59 UTC
74f71ad Pierre Schweitzer 13 August 2013, 11:39:47 UTC Also prune unused cores for cores changes tracking Fix a broken test that lead cores changes tracking NOT to be working (always null...) 13 August 2013, 11:39:47 UTC
d8400ff Pierre Schweitzer 13 August 2013, 11:33:47 UTC Add main advices first, so that they are executed first. This fixes arguments usage before they are even set. Display nbProcs in TProfilerAssert trace Prune cores with no changes on display 13 August 2013, 11:33:47 UTC
18b20ac Pierre Schweitzer 13 August 2013, 11:07:46 UTC Remove useless insertion (it always fails) 13 August 2013, 11:07:46 UTC
b0fcae3 Pierre Schweitzer 13 August 2013, 09:51:41 UTC Add a possibility to track function movement between machine cores. Will likely require fixes Using online processors as upper limit should be avoided in the future too... 13 August 2013, 09:51:41 UTC
