Intel Threading Building Blocks

Debug Versus Release Libraries

Threading Building Blocks includes dynamic shared libraries that come in debug and release versions, as described in Table 10-1.

Table 10-1. Dynamic shared libraries

Library	Description	When to use
tbb_debug tbbmalloc_debug	These versions have extensive internal checking for incorrect use of the library.	Use with code that is compiled with the TBB_DO_ASSERT macro set to 1.
tbb tbbmalloc	These versions deliver top performance.	Use with code compiled with TBB_DO_ASSERT undefined or set to 0.

All versions of the libraries support the Intel Thread Checker and Intel Thread Profiler. The debug versions always have full support enabled. The release version requires compiling code with the macro TBB_DO_THREADING_TOOLS set to 1 for full support.

Warning

The instrumentation support for the Intel Thread Checker becomes live after the first initialization of a task. If the library components are used before this initialization occurs, the Intel Thread Checker may falsely report race conditions that cannot actually occur.
