Hi Dave, It seems like forever you go you sent me patches to trinity to make it work on sparc. I'm curious if you've tried running it again more recently ? Given the work I've done it to do more creative things with VM related syscalls, I wouldn't be surprised if it also found some sparc specific bugs in thp. It should now also scale up to run a lot more child processes than the older version, with the -c option, which could be interesting on some of the bigger sparc machines. (It's entirely possible I've broken the compile on non-x86 in current git, but it shouldn't be much work to fix up). git://github.com/kernelslacker/trinity is where it lives now.
