I solved this issue by upgrading my GCC compiler on centOS, Initially, I had GCC version 4.8.0 and when I upgraded it to GCC 7.3.0. this problem of sequential running had gone.
I also added in my CMakeLists.txt file this :
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")

I solved this issue by upgrading my GCC compiler on centOS, Initially, I had GCC version 4.8.0 and when I upgraded it to GCC 7.3.0. this problem of sequential running had gone.
upgrading GCC 7.3 on CentOS 7
1 - update installed packages
sudo yum -y update
2 - Install GCC from the official CentOS repositories
sudo yum -y install gcc
3 - also install gcc-c++
sudo yum -y install gcc-c++
4 - install gcc from source, in fact, it is recommended to start a screen session before starting.
screen -U -S gcc
5 - get the tarball of the GCC
wget http://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-7.3.0/gcc-7.3.0.tar.gz
6 - Unpack the archive and get in the current working directory
sudo tar zxf gcc-7.3.0.tar.gz
cd gcc-7.3.0
7 - setup bzip2 and run the ‘download_prerequisites’ script. You have to run this from the top level of the GCC source tree.
sudo yum -y install bzip2
./contrib/download_prerequisites
8 - Once you get downloaded prerequisites, run this command to start configuring the GCC build environment
./configure --disable-multilib --enable-languages=c,c++
9 - Once it finishes, you've to compile the source code. It may take a few hours to complete, so be patient.
sudo make -j 4
sudo make install
I also added in my CMakeLists.txt file this :
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
