“The most important addition in GCC 4.2.0,” says Baishampayan Ghose, an Ubuntu hacker, “is the merge of the GOMP branch
into mainline GCC.” The GOMP branch of GCC was created a long time back
to implement OpenMP in GCC for the C, C++, and Fortran compilers.
OpenMP eases the process of creating code that can run in parallel.
Implementation-wise, OpenMP is a platform- and
architecture-independent application interface. It lets programmers
write parallelized code wherein a master thread creates multiple
“slave” threads to execute a code block in parallel and later merge
back into the master thread. Ghose explains that the addition of OpenMP
is a non-trivial improvement to the GNU Compiler Collection and will
make parallel programming simple on Free Software operating systems.
