</span>It looks like openmp/runtime/README.txt could use an update to clarify<br>
this status. The title is "README for the Intel(R) OpenMP* Runtime<br>
Library" and there's a of supported Intel architectures -- this gives<br>
a somewhat different impression than what's described in this thread.<br>
<br>
That said, I would also be happy to see the default switched to libiomp.<br>
