[cfarm-users] gcc304 (Mac M1) , gcc302 (OpenBSD) - updated

[Assaf Gordon]

Hello,

gcc304 (Mac M1) has been upgraded to Mac OS 12.2 ("Monterey").
gcc302 (OpenBSD) has been upgraded to OpenBSD 7.0 .


More about gcc304:

Recently this machine has been experiencing some stability and 
availability issues. I suspect this is due to some over-use (large/many 
processes, little available disk space, etc.).

As a temporary solution, stricter 'ulimits' are now in place:

   % ulimit -aS
   -t: cpu time (seconds)              unlimited
   -f: file size (blocks)              unlimited
   -d: data seg size (kbytes)          unlimited
   -s: stack size (kbytes)             8176
   -c: core file size (blocks)         0
   -v: address space (kbytes)          unlimited
   -l: locked-in-memory size (kbytes)  6000000
   -u: processes                       256
   -n: file descriptors                1024
   % ulimit -aH
   -t: cpu time (seconds)              unlimited
   -f: file size (blocks)              unlimited
   -d: data seg size (kbytes)          unlimited
   -s: stack size (kbytes)             65520
   -c: core file size (blocks)         unlimited
   -v: address space (kbytes)          unlimited
   -l: locked-in-memory size (kbytes)  10000000
   -u: processes                       512
   -n: file descriptors                1524

Additionally all processes will automatically start with "nice +4".

As for disk space:
There are currently about 63GB free (out of 228GB total),
with 82GB used by CFARM users and rest by the OS.

The "top consumers" are:
   865M	phargrov
   866M	gracinet
   1.1G	csmoe
   1.1G	nick
   1.1G	ppalka
   1.3G	florian2
   1.5G	assafgordon
   2.5G	thardin
   3.0G	haible
   4.4G	rocky
   9.1G	djb
   14G	vmakarov
   16G	iains
   18G	muller

If these are files used for recent testing - well, that's what this 
machine is for and that's OK (within reason).
But if these are stale files from older builds that aren't currently 
needed - please be a good netizen and clean up your home directory.
