Tuning the Mathematical Libraries

Principle

libamath is a subset of libm and contains a set of optimized mathematical functions. It optimizes exp, pow and log routines.

Procedure

1. Run the following commands to install the libamath mathematical Library.

   yum install glibc* glibm* -y

   unzip optimized-routines-master.zip

   cd optimized-routines-master

   mkdir -p /path/to/MATH

   cp config.mk.dist config.mk

   make -j 16

   make install

   cp -r ./build/* /path/to/MATH

2. Run the following commands to set the libamath mathematical Library environment variables.

   export PATH=/path/to/MATH/bin:$PATH

   export LD_LIBRARY_PATH=/path/to/MATH/lib:$LD_LIBRARY_PATH

3. Run the following command to add the following compilation parameter and link libamath to the application when compiling the application software.

   -L/path/to/MATH/lib -lmathlib
