Additionally there could maybe be a reference to the code, as examples
will get outdated. In this case that would be configure_base in
atlas/spkg-install [1], which is quite legible:
def configure_base():
isa_ext = ('None',)
thread_limit = 0 # disable threading in "base"
if conf['Intel?'] and conf['64bit?']:
print 'Generic configuration on Intel x86_64 compatible CPUs.'
arch = 'x86SSE2'
isa_ext = ('SSE2', 'SSE1')
elif conf['Intel?'] and conf['32bit?']:
print 'Generic configuration on Intel i386 compatible CPUs.'
arch = 'x86x87'
elif conf['SPARC?']:
print 'Base configuration on SPARC.'
arch = 'USIII'
elif conf['PPC?']:
print 'Base configuration on PPC.'
arch = 'PPCG4'
elif conf['IA64?']:
print 'Base configuration on Itanium.'
arch = 'IA64Itan'
else:
raise NotImplementedError, 'I don\'t know a "base" configuration for
your cpu.'
return (arch, isa_ext, thread_limit)
