Hi,
I'm trying to get octave to use both my CPUs, so far to no avail. Octave
insists on linking to the non_threaded libraries:
joan@calvin:~(0)$ ldd /usr/local/bin/octave-2.1.57
/usr/local/bin/octave-2.1.57:
liboctinterp.so => not found (0x0)
liboctave.so => not found (0x0)
libcruft.so => not found (0x0)
libalapack.so.1 => /usr/local/lib/libalapack.so.1 (0x28085000)
libcblas.so.1 => /usr/local/lib/libcblas.so.1 (0x28488000)
libf77blas.so.1 => /usr/local/lib/libf77blas.so.1 (0x284b2000)
libatlas.so.1 => /usr/local/lib/libatlas.so.1 (0x284d1000)
libreadline.so.5 => /lib/libreadline.so.5 (0x28de1000)
libncurses.so.5 => /lib/libncurses.so.5 (0x28e10000)
libg2c.so.1 => /usr/lib/libg2c.so.1 (0x28e52000)
libm.so.3 => /lib/libm.so.3 (0x28e70000)
libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28e8a000)
libc.so.5 => /lib/libc.so.5 (0x28f67000)
even though the threaded versions are there:
joan@calvin:~(0)$ ls /usr/local/lib/lib{cblas,alapack,atlas,f77blas}_r*
/usr/local/lib/libalapack_r.a /usr/local/lib/libcblas_r.a
/usr/local/lib/libalapack_r.so /usr/local/lib/libcblas_r.so
/usr/local/lib/libalapack_r.so.1 /usr/local/lib/libcblas_r.so.1
/usr/local/lib/libatlas_r.a /usr/local/lib/libf77blas_r.a
/usr/local/lib/libatlas_r.so /usr/local/lib/libf77blas_r.so
/usr/local/lib/libatlas_r.so.1 /usr/local/lib/libf77blas_r.so.1
Not even changing the ${BLAS_LIBS} in the Makefile to the *_r variants seems to
have any effect:
Installation prefix: /usr/local
C compiler: cc -mieee-fp -Wall -W -Wshadow -O -pipe -march=athlon-
mp -I/usr/local/include
C++ compiler: c++ -mieee-fp -Wall -W -Wshadow -O -pipe -march=athlon
-mp
Fortran compiler: f77 -O
Fortran libraries: -L/usr/local/lib -L/usr/lib -lg2c -lm
BLAS libraries: -lalapack_r -lcblas -lf77blas -latlas
FFTW libraries:
HDF5 libraries:
MPI libraries:
LIBS: -lreadline -lncurses -lm
Default pager: less
gnuplot: gnuplot
Do internal array bounds checking: false
Build static libraries: true
Build shared libraries: true
Dynamic Linking: true (dlopen)
Include support for GNU readline: true
Watching top during simulations shows that only one CPU is being used,
which is quite fustrating. Any hints on how to get it to use both CPUs?
tks
