I would hope this just be started and as users (like me) could just send in notes according to their experience. Here's the first line: BOOST_PP_CAT doesn't work with VC 6. Robert Ramey

Re: [boost] Geometric Algebra Library
by Tim Stevenson 10 Jun '04

10 Jun '04

Hi Jaap, I'm very interested in something like your library. I've only just started to wrap my head around geometric algebra and I've been confining myself so far to just playing with simple problems on paper to see how it removes special boundary case handling for some simple algorithms. The computational complexity of the higher dimensions has always concerned me but it sounds like you are doing a lot of compile-time optimisation to save wasted calculations at run-time. In a few months I'm planning to devote a considerable amount of time to investigating Geometric Algebra in a lot more detail and your library sounds like a good tool to "play" with. I use both VC++ and GCC and I would be willing to devote some time to investigate porting your library to the latest version of GCC. Tim.

uBLAS regression tests

Hello, currently uBLAS regression tests are defined in status/Jamfile directly. Will it be OK if I move them to libs/numeric/ublas? The reason I'd need that is that Boost.Build V2 version of uBLAS tests that was contributed by Michael Stevens lives in libs/numeric/ublas, and with the current setup its hard for me to automatically verify that V1 and V2 test results are the same. - Volodya

Instantiation of the global itself becomes an MT issue. That's what the double-checked locking pattern for singletons is for.

regression test tools ported to vacpp
by Toon Knapen 09 Jun '04

09 Jun '04

The regression test tools are finally ported to vacpp version 6 and the regression test status will again be updated every day at 6am CET (unless new changes break the compilation again). Please don't hesitate to contact me when you want some help porting your boost library to the IBM/VisualAge platform. toon

They are good notes. I'm aware of the portability issues. Doesn't mean you can't have valid platform specific singleton implementations that use the double checked locking pattern. The performance of the approach is too important to give up. Locking is slow. There are a lot of things you can't do portability in C++ which is one rationale for having libraries :-) Regards, Matt Hurd. _______________ Matt Hurd +61.2.8226.5029 hurdm(a)sig.com Susquehanna _______________ IMPORTANT: The information contained in this email and/or its attachments is confidential.

boost::any question
by Trey Jackson 08 Jun '04

08 Jun '04

All, I just started looking at boost::any, pretty nice. I looked at the implementation, and it uses (as you know) a pointer to an object (w/virtual methods) on the heap, and typeid to determine if conversion is possible. I understand the memory implications (a new object copied on heap). But I'd like to get a better handle on performance, namely: I'm unfamiliar with typeid - and how it's implemented. Does anyone have good pointers to how typeid is generally implemented? Or even specifically: I'm using gcc3.x on RH Linux. I'd just like to avoid/guarantee I'm not going to be hit by some O(N) look-up for using typeid a lot. thanks, TJ -- Trey Jackson tjackson(a)ichips.intel.com "Her hair glistened in the rain like nose hair after a sneeze." -- Chuck Smith, Woodbridge
