[rfc] Quadrature library for numerical integration of definite integrals
by Hugo Duncan 13 Dec '07

13 Dec '07

Hi, I have put together a quadrature library, for the numerical evaluation of definite integrals. I put this together to meet some requirements that I had. I would like to get comments on whether the scope, algorithms and approach used are of interest within boost. The code is based on QUADPACK's QAG and QAG global adaptive routines, using Kronrod-Gauss or Recursive Monotone Stable integration "kernels". This is not just a translation of the QUADPACK code, but tries to take a (reasonably) modern C++ approach. The RMS kernel is based on TOMS 691. Error estimation, choice of integration kernel, algorithm performance statistics, series limit acceleration algorithm, etc are all plugable. For the less brave, I would appreciate any comments you might have on a quadrature library in general. For the braver, the code can be found in the boost vault at http://www.boost-consulting.com/vault/index.php?direction=0&order=&director… The jamfile expects BOOST_ROOT to be defined. The code use the math toolkit from the same place in the vault. The location of the toolkit can be specified using the BOOST_MATH_TOOLKIT_ROOT environment variable, and by default is looked for in a directory boost-math-toolkit, parallel to BOOST_ROOT (ie in BOOST_ROOT/..) The code has been tested against QUADPACK and includes (very) rudimentary documentation, with examples. The code has been compiled only on windows, using MSVC 8 and gcc 3.4.4. Hugo

Multi Index Container ordered index - infinte loop when advancing iterator which is the end iterator

Hi All, Is this a known issue that if due to a wrong usage the .end iterator is advanced there is an infinte loop?

FW: is serialization library cross platform compatible
by Arunava Saha 12 Dec '07

12 Dec '07

Hi boost experts, I am using boost serialization library in one of my project. I have a question regarding that, is serialization library of boost cross platform compatible? By 'cross platform', I mean that, can we de-serialize a 64 bit dump in a 32 bit machine? Thanks, Arunava.

[mpi] SEEK_* defined, but shouldn't be
by Benjamin Collins 12 Dec '07

12 Dec '07

A common problem that occurs when building mpich2 is that SEEK_SET, SEEK_CUR, and SEEK_END are all defined. mpich2 (specifically mpicxx.h) requires them to be unset to avoid problems caused by both the MPI interface and stdio using them. Anyway, the suggested solution is to #undef each macro before #include <mpi.h>. I tried that in the mpi library, and it still failed to build. I also tried adding <define>MPICH_IGNORE_CXX_SEEK=1 to the mpi Jamfile. Alas, it didn't fix the problem either. The failure occurs when building release/threading-multi/collective.o How are users of mpich2+boost::mpi getting around this problem? -- Benjamin A.

[review] Boost.Functional/Forward - result
by John Torjo 12 Dec '07

12 Dec '07

Hi all, I'm happy to announce that The Boost.Functional/Forward library has been accepted into Boost. Congrats to Tobias for a great lib! Summary: 5 reviews, all positive. Suggestions for improvement: - Automatically detect if the compiler supports variadic templates and rvalue references and use those instead. This can be a useful portability utility when such compilers become more common. - It should use compressed_pair to store the wrapped function object to take advantage of EBO. - more tweakable parameters for specific uses - like, arity 3 for function X, and arity 5 for function Y - Docs: add more material explaining the forwarding problem - Docs: should be explicitly specified that the wrapped function object must be result_of compatible - Docs: A discussion of the impact of the library on compile time (especially with high values of N) Best, John -- http://John.Torjo.com -- C++ expert ... call me only if you want things done right

pa-risc HP-UX compatibility.
by Jurko Gospodnetić 12 Dec '07

12 Dec '07

Hi. HP-UX system header '/usr/include/machine/reg.h' found on pa-risc HP-UX 11.11 defines R1, R2, R3, etc. macros which conflict with some boost headers. Conflicting headers found in Boost 1.34.1. are 'boost/iterator/iterator_facade.hpp' (several template parameter names) and 'boost/test/test_tools.hpp' (one local variable name). We have not checked the current trunk/1.35 release branches. Could these and any other conflicting files be updated to not use these identifier names? Such changes should be trivial renames. Also, most likely some Boost coding convention documentation should be updated to reference this. We ran into this problem when looking into porting the Boost ASIO library to HP-UX and working around this problem will be necessary in order to get this port working. Note though that newer HP-UX releases do not have this problem (tested on HP-UX ai64 11.23) Hope this helps. Best regards, Jurko Gospodnetić
