=== shinmen [n=shinmen@nat1.inalambrica.net]  has left #ubuntu-ports ["Ex-Chat"] 
=== braddr_ drools over a gcc build with gmake -j 32.. and actually using all 16 cpus for a lot of the build.
[07:58] <fabbione> braddr_: it's much more fun if you just do make -j
[07:58] <braddr_> heh
[07:59] <braddr_> I figured 2x cpu's is probably good enough.. but yes, I'll give that a whirl.
[07:59] <braddr_> this is the first build I've done on the box, and it's having to do a bunch of configure scripts run, really limiting the parallelism.
[08:00] <fabbione> i can imagine
[08:00] <braddr_> after it finishes, a make clean; make ought to get much more opportunity
[08:01] <braddr_> any word from davem?  I assume he's still wrestling gdb and mono to the ground.
[08:01] <fabbione> he is fighting with a bad cold
[08:02] <fabbione> so he is not hacking much around
=== braddr_ nods.. "I know the feeling.. knock on wood, it's been a while since my last illness."
[08:37] <braddr_> 370 processes: 213 sleeping, 139 running, 1 zombie, 17 on cpu
[08:37] <braddr_> yes, unrestricted make -j is kinda fun
[08:42] <fabbione> braddr_: when we started testing Niagara, davem was soft with -j32
[08:43] <fabbione> after i started with -j 512 we found all kind of smp bugs :P
[08:43] <braddr_> heh
[08:43] <braddr_> not suprisingly, solaris is holding up quite well under the load
[08:43] <fabbione> we do too now
[08:44] <braddr_> I'm willing to be convinced. :)
[08:44] <fabbione> i have been sort of bashed by my boss, because nagios woke up the sysadmins due to "a few machines complaining load over 1000"
[08:45] <fabbione> (i was preparing a kernel security release a few months back)
[08:45] <braddr_> whee
[08:45] <fabbione> well i was make -j on all arches at the same time
[08:45] <fabbione> :)
[08:45] <braddr_> with that kinda load, you're wasting an awful lot of time in context swapping
[08:46] <braddr_> ok, maybe not a lot, but..
[08:46] <braddr_> 11m build for gcc 4.0.3 for c,c++
[08:47] <braddr_> pretty decent
[08:47] <fabbione> point is that i was more waiting for I/O
[08:47] <fabbione> since the kernel was already in ccache
=== braddr_ nods.
=== daq4th [n=darkness@netstation-005.cafe.zSeries.org]  has joined #ubuntu-ports
[11:06] <braddr_> fabbione: re: that 16 cpu t2000.. I'll be keeping it rather than getting the 32 cpu version.  Not worth the hassle to get the right model.
[11:07] <braddr_> so no worries about loosing the test case
=== jb-home tries to imagine the noise from a 32 CPU sparc box...
[11:09] <braddr_> exactly the nose of a 16 cpu box.. in both of the cases for the t2000 series, its 1 physical core.
[11:09] <braddr_> er.. 1 physical unit, just a varying number of cores.
[11:10] <braddr_> the t2000 hardware is _nice_, from a physical layout standpoint.  It's also nice from a performance standpoint.
[11:10] <braddr_> it's unfortunatly pricy from a suck you dry standpoint.
