DESCRIPTION = "Parallelism library for C++ - runtime files \
|
TBB is a library that helps you leverage multi-core processor \
|
performance without having to be a threading expert. It represents a \
|
higher-level, task-based parallelism that abstracts platform details \
|
and threading mechanism for performance and scalability."
