<div>JLab's Experimental Physics' batch farm CentOS 6.5 nodes
are now in production service; this brings the batch farm to
almost 4000 cores.Please plan your move to this updated
environment; the current 1400 core CentOS 6.2 environment will
be migrated by summertime to run 6.5. Over the coming year,
we will also begin testing with CentOS 7 for future use.<br>

<div>The CentOS 6.5 interactive system for users is available
via the alias "ifarm65.jlab.org"; more interactive nodes will
be added using this alias as usage increases. Use the tag
"OS: centos65" in your batch job submission scripts. <br

The 104 new Physics nodes for the data analysis
farm cluster have just arrived (well, except their
power cords, coming tomorrow). These farm14* nodes
are dual Intel E5-2670v3 (Haswell) 12 core, 2.3
GHz, with 32 GB DDR4-2133 memory -- the leanest
memory configuration in the farm (less than 1 GB
per job slot on serial jobs). They will run with
as many slots as experience shows they can handle,
based upon statistical measurements in actual
running. Their network includes 20 gigabit
Infiniband DDR for I/O to the Lustre and ZFS
filesystems. Their initial installation in the
F112 Data Center begins this week.<br>
<br>
</div>
<div style="color: rgb(0, 0, 0); font-weight:
normal; font-style: normal; text-decoration: none;
font-family: Helvetica, Arial, sans-serif;">This
farm node installation will add a total of 104 *
24 = 2496 cores to the existing 1400 core farm.
We will be working with early users to identify
the correct operating system and kernel to
install, then move the systems to production mode
as their burn-in proves successful. More details
to follow.</div>
