Summary0021961: Paralleling BRepMesh using Intel TBB tools
DescriptionThis record is made for integration of long-term development of parallelized
version of BRepMesh component. Now it uses Intel TBB library for both
paralleling tools and memory manager.

Parallel processing is available on WNT and Linux only and requires TBB library
installed. Configuration options for TBB (installed currently on Linux in /dn04/
KAS/dev/abv-parallex/work) are added in adm/CSF.edl, *_CMPLRS.edl files in
Standard and BRepMesh packages, and EXTERNLIB files in the same packages.

Parallel execution of BRepMesh (Incremental Mesh algorithm) is used when
Standard::IsReentrant() is True; otherwise (or when TBB is not available) usual
"for" cycle is applied.

Additional option MMGT_OPT=2 is supported; it uses TBB memory allocator instead
of OCCT one (=1, current default) and standard RTL one (=0).
TagsNo tags attached.
