SPRNG 4.0 Installation with Intel C/C++/Fortran compilers and Intel MPI Library
From HP-SEE Wiki
Contents |
Prerequisites
- Intel C/C++/Fortran compilers
- Intel MPI Library
Downloading SPRNG 4.0 source code
- Download the SPRNG4.0 from here to the location where you want to place the source.
- In the directory where you downloaded the sprng4.tar.gz execute
- zcat sprng4.tar.gz | tar xovf -
- The source will be extracted to the directory sprng4, navigate to it to continue with the installation.
- cd sprng4
Editing the SPRNG 4.0 source code
During the installation of SPRNG 4.0 an error, related to the Fortran wrappers written in C/C++ is encountered. The error is caused by the two different conventions for linking Fortran – adding one or two underscores to the Fortran function when using it in C. To fix that simply replace the double underscore in the definitions in SRC/fwrap.h with a single underscore:
- sed -i 's/__/_/g' SRC/fwrap.h
Configuring SPRNG 4.0
Now that the Fortran wrapper definitions are fixed, you must configure SPRNG 4.0 installation properly, that is you need to set the install location and the compilers to use for the build:
- ./configure --prefix=/<path>/<to>/<sprng>/ CC=mpiicc CXX=mpiicpc F77=mpiifort MPIF77=mpiifort MPICXX=mpiicpc
Note: You should specify the MPI versions of the compilers even for the non-MPI configuration variables.
Building and installing SPRNG 4.0
- To build SPRNG 4.0 enter the following command:
- make
- To install SPRNG 4.0 in the specified with prefix directory use:
- make install
Verifying SPRNG 4.0 installation
To verify your SPRNG 4.0 installation, navigate to check/ and run the check script:
- cd check
- ./checksprng
Other Issues
Since make install does not copy the headers from sprng4/include to the installation directory, you must copy them manually:
- cp -r include/ /<path>/<to>/<sprng>/
