Dual-core Opteron Support on RHEL v3

Hi All,

I don't run an Opteron-based box at all I seem to recall that someone
(Brian Long from Cisco, maybe) had some cache-trashing & performance
issues on dual-core opteron systems from Sun (V20z and V40z) when running
some huge parallel makes on these boxes (RHEL3 U5 & U6). I don't know if
these were resolved but the issues seemed serious enough to be taken with
care.. I don't know if RHEL4 handles this differently, though..

PS: Look in the RHEL3 archives for the "Dual-core & Parallel Compile
Issues" thread (no pun intended).

Vincent
