Hi all,
I just discovered that it seems like the memory modules in porter and
stout have ended up in the wrong locations, and the CPU memory bandwidth
is a fair bit lower than it could be for that reason.
http://www.supermicro.com/manuals/motherboard/C606_602/MNL-1491.pdf#page=36
says for our configuration (two CPUs, eight DIMMs), the memory should be
in the following slots:
P1-DIMMA1/P1-DIMMB1/P1-DIMMC1/P1-DIMMD1
P2-DIMME1/P2-DIMMF1/P2-DIMMG1/P2-DIMMH1
According to
dmidecode -t memory | egrep 'Size|Locator' |grep -v Bank
the memory actually is in the following slots:
P1_DIMMA1: No Module Installed
P1_DIMMA2: No Module Installed
P1_DIMMB1: 8192 MB
P1_DIMMB2: 8192 MB
P1_DIMMC1: No Module Installed
P1_DIMMC2: No Module Installed
P1_DIMMD1: 8192 MB
P1_DIMMD2: 8192 MB
P2_DIMME1: No Module Installed
P2_DIMME2: No Module Installed
P2_DIMMF1: 8192 MB
P2_DIMMF2: 8192 MB
P2_DIMMG1: No Module Installed
P2_DIMMG2: No Module Installed
P2_DIMMH1: 8192 MB
P2_DIMMH2: 8192 MB
Stout is the same. So this should get fixed, ideally somewhat soon.

Porter and Stout are back up!

Hi all,
I will be shutting down porter and stout in about an hour to rearrange memory. This shouldn't take more than about 20 minutes. I'll send out a notification when they're back up.

Hi all,
Sometime in the next 24 hours I will shut down porter and stout to rearrange memory. I will send out another email about 1 hour before it happens. Contact me if this is going to be a problem.

Hi all,
You've probably had trouble getting to porter/stout from UIUC wifi over
the past week or so. If you did, I'm sorry--I ultimately caused this,
although I didn't mean to. (I installed a piece of software called
"docker" whose default IP range clashes with UIUC wifi.) At any rate,
this should be fixed now.
Sorry for the inconvenience!

Something seems to be up with the University firewall. Luke had trouble
yesterday. Now that I'm on Wifi, I can't either. I didn't have trouble
from a wired connection. Interestingly, bouncing through any off-campus
host seems to make it work.
