<p>Hello everyone,</p>
<p>I just wanted to let you know that the upgrades of the Hall A
counting house computers, announced a week ago, have been
completed.</p>
<p>We now have four main analysis machines, aonl1-4, each with 128
threads and 512 GB of RAM. aonl2-4 are ca. 25% faster than aonl1.
There's also a fifth, slower machine, aonl5, intended for
auxiliary jobs.</p>
<p>Additionally, we have a new file server, mollerfs, whose disk,
over 215 TB, is visible under/mollerfs/work1. This is in addition
to the old /chafs[12]/work1 disks. mollerfs is meant for MOLLER
online analysis (prompt replay, etc.)</p>
<p>Feel free to start using these machines, and please let me know
if you notice anything amiss.</p>
<p>Cheers,</p>
<p>Ole</p>

<p>Hello everyone,</p>
<p>sorry to spring this on you on short notice, but it's probably
not a big deal re ongoing work:</p>
<p>We are planning to upgrade the hardware of the counting house
machines aonl2-aonl4 tomorrow afternoon, Saturday, Dec 13. The
machines will be down for at least a few hours, possibly into
Sunday. The work disk (/aonlN/work1) of each host has been
backed up and will be restored after the upgrade. There should
be no other user data on these hosts. Very brief network
interruptions are possible, but unlikely. We'll let you know
when things are stable again.</p>
<p>aonl1 and the DAQ and slow controls machines will stay up
unless something unforeseen happens.</p>
<p>The new machines will be WAY faster than the ancient ones they
replace, so there's something to look forward to.</p>
<p>We'll also get a new file server with O(200 TB) disk space.
Details will be shared once it is configured.</p>
<p>Cheers,</p>
<p>Ole</p>
