3D Fast Fourier Transform Library for Blue Gene/L

Operating systems: CNK/Linux®

Hardware: IBM® Blue Gene®/L architecture

Software: IBM Engineering and Scientific Software Library (ESSL)

1. Unpack the files with the command gunzip bgl3dfft_1.0.tar.gz and tar -xvf bgl3dfft_1.0.tar. The file contains a bgl3dfft_1.0 directory with the following subdirectories:
   • The inc/ directory contains the include files.
   • The obj/ directory contains the dbgl3dfft.o and sbgl3dfft.o object files, for the double and single precision respectively, after the installation is completed.
   • The tst/ directory contains sample code and a makefile about how to use the BGL3DFFT interfaces and how to link to the BGL3DFFT library.
   • The doc/ directory contains a documentation file.
2. Make sure you have access to IBM ESSL library; it is required by BGL3DFFT.
3. In order to test the BGL3DFFT library, edit the makefile in the tst directory to point to the ESSL directory.
