Note that switching to openblas-openmp (libopenblaso.so) should be
thread-safe and will probably get you a better performance than Atlas.
Also, Fedora packages blis (which provides
/lib64/blisblas/libblas.so.3). It seems to be thread-safe should be
more performant than Atlas too.

Changing the BLAS from openblas on a F32 box
Of course, even a simpler trick is to launch R as follows:
LD_PRELOAD=/lib64/atlas/libsatlas.so.3 R
and then the symbols in libsatlas take precedence over libopenblas. Or
a mix between both alternatives, i.e., setting
LD_PRELOAD=/path/to/some/link R
and then change that link to point to openblas, atlas... Whatever
suits you best.
