Documentation for STXXL library

1.2.1

The core of STXXL is an implementation of the C++ standard template library STL for external memory (out-of-core) computations, i.e., STXXL implements containers and algorithms that can process huge volumes of data that only fit on disks. While the compatibility to the STL supports ease of use and compatibility with existing applications, another design priority is high performance. Here is a selection of STXXL performance features:

Supported Operating Systems

Supported Compilers

The following compilers have been tested in different STXXL configurations. Other compilers might work, too, but we don't have the resources (systems, compilers or time) to test them. Feedback is welcome.

The compilers marked with '*' are the developer's favorite choices and are most thoroughly tested.

 x   = full support
 o   = partial support
 -   = unsupported
 ?   = untested
 MCSTL = supports parallelization using the MCSTL library
 PMODE = supports parallelization using libstdc++ parallel mode
 ¹   = you may have to add a -gcc-name=<gcc-x.y> option if the system default
       gcc does not come in the correct version:
       icpc 9.0: use gcc 3.x
       icpc 9.1: use gcc before 4.2
       icpc 10.x with mcstl support: use gcc 4.2
 ²   = MCSTL has been superseded by the libstdc++ parallel mode in GCC 4.3,
       requires g++ 4.3.2 (prerelease) or later

Supported BOOST versions

The Boost libraries are required on Windows platforms using MSVC compiler and optional on other platforms.

STXXL has been tested with Boost 1.34.1. It also compiles using Boost 1.35.0 without problems, but hasn't been thoroughly tested in this setting. Other versions may work, too, but older versions won't get support.
