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:
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.

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.
