> Obtaining optimized BLAS routines for HPC platforms > (e.g. O3K, Altix, Opteron, ...) > [email protected], 9-Sep-2004 > > 1. > Go to > https://www.cs.utexas.edu/users/kgoto/ > which has a set of high performance BLAS libraries for > all kinds of platforms. > > 2. > Download (e.g. for Opteron) > https://www.cs.utexas.edu/users/kgoto/libraries/libgoto_opt64p-r0.94-2.so.gz > which seems to be the suitable one for your Opteron 64 bit multi-threaded > and put them in a directory, e.g. ~/mylib/ > > 3. > As per website instruction, > also need the file xerbla.f > https://www.cs.utexas.edu/users/kgoto/libraries/xerbla.f > Download it into the MITgcm/optim/ directory as > xerbla.F (note capital F) > (maybe cleaner to generate an object file and keep it in ~/mylib/ ) > > 4. > in .bashrc added line > export LD_LIBRARY_PATH=~/mylib > (consistent with the directory where I keep the library) > > 5. > in MITgcm/optim/ > edit the Makefile as follows > * add xerbla.F to $SRC > * add -L~/mylib/ $LIBDIRS > * add -lgoto_opt64-r0.94-2 $LIBS > and ignore > -lblas1 > > That works. Some BLAS libraries provided in lsopt/ are SGI O3K: libblas1.a_IRIX64.gz SUN: libblas1.a_SUN.gz SGI Altix: libgoto_it2-r0.95.so.gz PC Pentium4: libgoto_p4_512-r0.94.so.gz
