We now have a POWER10 machine in the Compile Farm:
It is donated by IBM, and hosted at OSUOSL like most Power machines. Thanks!
It is an IBM E1050, 192 hardware threads, 2TB RAM, 11TB disk. It runs AlmaLinux, a RHEL descendant / clone.
It is open for general use immediately. Enjoy, but use it responsibly: most importantly, always be aware other people want to use it as well :-)
GCC bootstrap takes 26m, and testsuite takes 6m. With --enable-languages=all. But Ada and D did not actually build, I'll work on getting some working pre-built compilers for those installed in /opt/cfarm for that, which you can use to build new compilers with.
Thanks to everyone involved for making this reality at long last!
