The machine is now ready for buildbot!
Aarch64, Ubuntu 16.04.5 LTS, 96 cores
I’ve setup buildbot-slave-0.8.14 in a virtualenv/
(Oddly, I had to install twisted==16.4.1, as anything newer than that caused a hang).
I’ve manually checked you can build gdb and run the testsuite.
My recent experiments with the testsuite on Aarch64 show all the threaded tests
are quite racy on a fully loaded ubuntu, whereas on redhat/suse they are fairly
stable. I’m still looking into why this is. But, in the short-term maybe we should
restrict the number of jobs to 32 (or maybe even fewer?)
Sergio, could you please add the relevant server config.
Thanks,
Alan.
