Hello there,
I start with the second question: Is there a convenient way to let GSL use MKL
or ACML instead of the native BLAS?
The more serious problem is this:
I am trying to install GSL v.1.8 on an Opteron system (SLES 9). After
compiling just with -O2 the "make check" fails with the following messages.
----------------------------------------------------------------
PGI:
----------------------------------------------------------------
FAIL: gsl_complex_polar imag part at (r=-1.5,t=0) (-1.5 observed vs -0
expected) [2]
...
Thes failures are reported for gsl_complex_log, gsl_complex_log10,
gsl_complex_exp, gsl_complex_sinh, gsl_complex_cosh, gsl_complex_csch,
gsl_complex_sech as well.
----------------------------------------------------------------
Pathscale 2.4 :
----------------------------------------------------------------
FAIL: gsl_vector_char_scale by 2 stride=1, N=87 [7519]
FAIL: gsl_vector_char_add_constant stride=1, N=87 [7520]
...
The same for .._uchar_..
----------------------------------------------------------------
Intel 9.1
----------------------------------------------------------------
FAIL: SV_decomp nan5 [197]
FAIL: Singular Value Decomposition [66871]
singular value 4 = 5 vs previous 0
FAIL: SV_decomp_mod nan5 [167097]
FAIL: Singular Value Decomposition (Mod) [233771]
FAIL: test
===========================
I did some double-checks and forced the compilers to strict IEEE arithmetics:
PGI: -Kieee shows no different results
-O0 -Kieee reports:
FAIL: gsl_block_char_fprintf and fscanf [136]
FAIL: gsl_block_char_write and read [149]
Pathsale: -fno_unsafe-math-optimizations shows no different results
Intel: -mp WORKS WELL! - No failures reported.
Do you have any idea what goes wrong?
Thank You
Ulf
