Update.
1 > Obtaining optimized BLAS routines for HPC platforms
2 > (e.g. O3K, Altix, Opteron, ...)
3 > heimbach@mit.edu, 9-Sep-2004
4 >
5 > 1.
6 > Go to
7 > http://www.cs.utexas.edu/users/kgoto/
8 > which has a set of high performance BLAS libraries for
9 > all kinds of platforms.
10 >
11 > 2.
12 > Download (e.g. for Opteron)
13 > http://www.cs.utexas.edu/users/kgoto/libraries/libgoto_opt64p-r0.94-2.so.gz
14 > which seems to be the suitable one for your Opteron 64 bit multi-threaded
15 > and put them in a directory, e.g. ~/mylib/
16 >
17 > 3.
18 > As per website instruction,
19 > also need the file xerbla.f
20 > http://www.cs.utexas.edu/users/kgoto/libraries/xerbla.f
21 > Download it into the MITgcm/optim/ directory as
22 > xerbla.F (note capital F)
23 > (maybe cleaner to generate an object file and keep it in ~/mylib/ )
24 >
25 > 4.
26 > in .bashrc added line
27 > export LD_LIBRARY_PATH=~/mylib
28 > (consistent with the directory where I keep the library)
29 >
30 > 5.
31 > in MITgcm/optim/
32 > edit the Makefile as follows
33 > * add xerbla.F to $SRC
34 > * add -L~/mylib/ $LIBDIRS
35 > * add -lgoto_opt64-r0.94-2 $LIBS
36 > and ignore
37 > -lblas1
38 >
39 > That works.
