Details:


I built octave 3.4.2 as follows:

export
CPPFLAGS='-I/usr/apps/libraries/HDF5/v1.8.4p1-intel-mvapich/serial/include
-I/state/partition1/jpg/pcre-8.12/build/include'
export LIBS=-L/state/partition1/jpg/pcre-8.12/build/lib
export PATH=/usr/apps/doc/texinfo/bin:$PATH
COMPILER=/usr/apps/compilers/gcc-4.4.6
COMPILER_BIN=${COMPILER}/bin
export CC=${COMPILER_BIN}/gcc
export CXX=${COMPILER_BIN}/g++
export F77=${COMPILER_BIN}/gfortran
export LD_LIBRARY_PATH=${COMPILER}/lib64:$LD_LIBRARY_PATH
export F77_INTEGER_8_FLAG=-fdefault-integer-8
../configure --prefix=/usr/apps/math/octave --enable-64
--with-blas='-L/usr/apps/compilers/intel/mkl/lib/em64t  -Wl,--start-group
-lmkl_gf_ilp64 -lmkl_gnu_thread -lmkl_core -Wl,--end-group -fopenmp -lpthread'
--with-lapack='-L/usr/apps/compilers/intel/mkl/lib/em64t -Wl,--start-group
-lmkl_gf_ilp64 -lmkl_gnu_thread -lmkl_core -Wl,--end-group -openmp -lpthread'
--with-fftw3-libdir=/usr/apps/math//fftw/v322double-openmp/lib
--with-fftw3-includedir=/usr/apps/math//fftw/v322double-openmp/include
--with-hdf5-libdir=/usr/apps/libraries/HDF5/v1.8.4p1-intel-mvapich/serial/lib
--with-hdf5-includedir=/usr/apps/libraries/HDF5/v1.8.4p1-intel-mvapich/serial/include
--disable-docs

with gcc 4.4.6 and --enable64.

When I run octave, I still get the following error message when I attempt to
allocate a large array:

error: memory exhausted or requested size too large for range of Octave's
index type -- trying to return to prompt


Please see the attached code sample. Its a matrix inversion modified from
matlab's hpccLinPack.m benchmark.

It runs for input arguments of up to ~ 2.^15 (the matrix rank). For 2.^16 it
runs for hours and never finishes, while for 2.^20, for example, it gives the
above memory error.

Thanks,

Jerry
