hi all BRAHMS 0.7.3 (and new and improved documentation) is now available through the BRAHMS website http://brahms.sourceforge.net there's no urgent need to upgrade, but sooner rather than later is recommended. you will have to recompile native components, but won't have to change code in most cases. there are some path changes to perform for all components. see the attached RELEASE NOTES for full details. this release is "for" various improvements to Concerto to support our work at BRL. other significant actions are bindings ported to Octave (3.2.0), BRAHMS ported to Mac OSX (Snow Leopard), and namespace paths simplified. please distribute this notice as appropriate. cheers mitch |

hi all we found a bug in 0.7.2 (Matlab/Python users only). please see: http://brahms.sourceforge.net/knownissues.php a patch to fix is available at source forge. cheers mitch |

hi all i've added a new page to the website, at http://brahms.sourceforge.net/knownissues.php known issues with 0.7.2, along with workarounds, will be posted here as they accumulate (one so far). please check this page for the latest information before reporting any bugs. note that this page is not linked from the current version of the docs - this will be corrected with the next docs release. cheers mitch |

hi all BRAHMS 0.7.2 is now released at SourceForge, with associated documentation. please read the Release Notes (installed with the package, or available on the download page from SourceForge). find all this stuff through... http://brahms.sourceforge.net and please be careful to download 0.7.2 - i can't persuade the weird SF website to stop displaying 0.7.1 as the default download. this release is "for" the promotion of the Standard Library to its permanent home, as promised with the 0.7.1 release. this was the final interface to be frozen, so components compiled against 0.7.2 should not need recompiling against future releases. upgrading is expected to require text-search-replace dev/std with std/2009 to account for the promotion, and recompiling everything (details are in the release notes). if you encounter any problems beyond this, and you can't quickly figure it out, please get in touch with me directly. once you're up and running, please ask future questions (i.e. not related to the 0.7.2 upgrade) in the help forum... http://sourceforge.net/forum/forum.php?forum_id=676910 in addition... MPI is now supported on windows and linux, but is beta and may be buggy. also, you will need a build of MPICH2 that supports MPI_THREAD_MULTIPLE. this may or may not exist for your chosen platform (installed on ACE, for example, but the build does not also support myrinet). we have switched to MPICH2 from OpenMPI, because OpenMPI did not support that flag and there was no indication that it would anytime soon. in future, we can add support for additional MPI implementations; please get in touch if you have requirements in this regard. there have been some major performance enhancements, and the inner loop is now running similarly fast on all platforms under all conditions. within-thread per-process iteration time is now in the 2-300 nanosecond region on recent hardware, which i think it's fair to say is blisteringly fast. in addition, concerto starts up much faster, and everything is just to be honest generally faster. this is largely because... the architecture has undergone a major refactoring to rationalise it, with the goal that it now (i hope) will be intuitive to understand for another human being. therefore, other people can now contribute to BRAHMS's development if they want to. i bet you're all very excited. in particular, two things will be done sooner rather than later are the creation of a design GUI for SystemML systems and the commissioning of the SystemML server. the former is being managed by kevin, the latter by me; both are currently planned to appear in some form by the end of this year. cheers mitch |

hi guys BRAHMS 0.7.1 is now released at SourceForge, and associated documentation at the new BRAHMS website, link below. please read the Release Notes (installed with the package, or available on the download page from SourceForge). http://brahms.sourceforge.net this is a bugfix release over 0.7.0 - one of those bugs was that component management was difficult, so the new BRAHMS Manager is technically a bugfix, though it may look on the surface, like a feature addition :) if you are running Matlab R14 SP2, there is a Matlab bug that manifests when using the BRAHMS Manager; please see the page "Known Issues" in the docs. also note that the pbwiki pages are being dismantled as we speak - most of the information previously available there has been migrated to the BRAHMS website. the wiki will remain open for discussions, and will continue to hold some "misc" data until it finds a more appropriate home. the overall goal of the SystemML project was to allow publishing of models to the community that will remain interoperable indefinitely into the future. one development step remains before it becomes possible to fulfil this goal, and that is to bring the standard library components off the dev/ branch of the tree, and freeze their interfaces (where models interact with the standard library, these interfaces must be fixed just like those with the framework). this will be done, more or less, on demand. therefore, if you are intending to publish a model written in BRAHMS, and want to take advantage of the SystemML publishing model (rather than just saying your users must use BRAHMS version x.x.x to run your model), please let me know well in advance so that i can get this process moving for the parts of the SL that are relevant to you. if you need to publish a model in a hurry, prior to this, there are less slick alternatives - please get in touch with me. ABRG users: RCs have been cleared from ACE, please use the link at /usr/local/abrg/brahms/SystemML from now on. i've left the RC link for now, so your stuff should continue to work without changes, but this link will probably disappear in future. cheers |
