With assistance from a local hardware vendor, I hope to observe OpenIndiana running (or not) on a two-socket Opteron 6200 system, at least for an hour or two.
I did get an opportunity this past weekend to test a two-socket Opteron 6220 (two sockets of 8 cores each at 3GHz clock) system. See http://www.cpu-world.com/CPUs/Bulldozer/AMD-Opteron%206220.html for an overview of the chip.
I tested under OpenIndiana and Ubuntu Linxu. OpenIndiana seemed to run fine and produced better multi-thread (OpenMP) performance with GCC than Ubuntu Linux did. I tested with the AMD Open64 compiler under Linux with Bulldozer optimizations and did notice that performance was often/usually considerably better than when using the Ubtuntu-provided GCC.
There was evidence of the "turbo" mode being active with just a few threads running.
I could not tell if FMA was working correctly on the OpenIndiana system. No faults or fault events seemed to have been reported.
