Adding new AIX machines

[mhdawson]

I now have access to one of the new AIX machines from osuosl, the other 2 are still being configured for networking.

Opening this issue for awareness and to capture any info while doing the install.

[mhdawson]

First machine added (https://ci.nodejs.org/computer/test-osuosl-aix61-ppc64_be-1/). A few tweaks to the instructions were required. PR for those here:
#461

built/ran tests, 2 new failures. Failures covered by this issue: nodejs/node#7973

[mhdawson]

Build/test time seems to be ~30 mins on the new machine, which is about the same as the slowest platforms so once we get the second machine on-line will plan to add to regular regression runs.

@mhdawson is that with ccache? 30min tests sounds awfully slow.

[mhdawson]

ccache is installed and I think it should be being used but I was planning to double check

[mhdawson]

Good news is ccache was not properly in the path, so we should do better, will fix that up.

[mhdawson]

Ok ccache is working now and down 19 mins. It seems that the node-test-commit-linux job seems to typically run 20 mins as do a few of the sub jobs I looked at so seems in the right ballpark. https://ci.nodejs.org/job/node-test-commit-aix/288/nodes=aix61-ppc64/

[jbergstroem]

Are you using JOBS?

[mhdawson]

Second machine almost ready, just needs to be added to firewall

[mhdawson]

@jbergstroem the parallelism was previously set to 1 but I changed that to 5 as part of the change since it looked like that was how many cpus were available on the new machines. So right now it has -j 5

[mhdawson]

I think this means we have 5 procs

bash-4.3# /usr/sbin/lsdev -C -c processor
proc0 Available 00-00 Processor
proc4 Available 00-04 Processor
proc8 Available 00-08 Processor
proc12 Available 00-12 Processor
proc16 Available 00-16 Processor
bash-4.3#

[jbergstroem]

On the phone, will add shortly!

Second machine in and working now.

Will plan to stitch AIX into the regular regression runs on Monday. There are still some failures (AIX was green but there are issues related to malloc bnoorhuis is working on and one new issue seen on the new machines), but I think its still good to be able to tell if commit introduce new failures.
