New description:
Many times the binaries cause trouble since we are building ATLAS with
SSE3. So add a special flag which given the following setting
{{{
SAGE_SIMD_MODE=SSE2
}}}
produce an SSE2 only binary. If those flags are set we also need to make
sure that sage-flags are set to sse2 only, i.e. no pni, no ssse3 or
sse4_*.
Cheers,
Michael
