[CP2K-user] configuring openmpi with --disable-builtin-atomics option?

[Mozhdeh]

Dear developers
I am using an Ubuntu 16.04 distribution with gnu compilers. I am forced to 
use another program package with a dynamic use of openmpi library.  I did 
echo following paths to .bashrc file:

export 
PATH="$PATH:/home/mozhdeh/cp2k/tools/toolchain/install/openmpi-3.1.3/bin"
export 
INCLUDE="$INCLUDE:/home/mozhdeh/cp2k/tools/toolchain/install/openmpi-3.1.3/include"
export 
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/mozhdeh/cp2k/tools/toolchain/install/openmpi-3.1.3/lib"
 
but I noticed that this version of openmpi should be configured by  
--disable-builtin-atomics   for the mentioned package.

My question is that is it safe for cp2k performance to compile openmpi with 
that option, again?
I appreciate any comment.
Thanks in advance
