No public stocks, yet....

There is something real here, and investors aren't as enthusiastic
as they once were.  Once bitten twice shy as they say.

The story Ron doesn't tell is how much testing putting LinuxBIOS on
a 1000 node cluster gives you.  Whenever I upgrade the bios it runs
through a rigorous 1000 boot test, catching all kinds of rare and
difficult to reproduce bugs.   Whenever we do a full software reinstalled
I get a 3000 boot test that only lasts about 10 minutes.

I have been tracking a weird issue all day and so far I have seen
about 2850 boots go by, and I am only debugging on a 10th of the
entire cluster.

I send Ron a romimage and he reports back that it is stable on his
development cluster.  And I am screaming about how flaky it is in
production.  Though happily I have finally had a stable build, as long
as people don't run LM_sensors and get the hardware in a confused state.

In my case things would be a lot easier if I wasn't doing the
dance of the three hardware bugs.  But hey I have to live with
the components that are on the motherboard.

Big clusters are fun in other ways.  The scale is huge.  MCR is
recently stable enough that we can start running some big jobs on it.
And even with jobs running on only half the cluster we are overloading
the air conditioning.  I can practically hear the alarms from where
I am sitting 30 miles away....
