<b>Subject: </b>Re: New nodes<br>
<br>
<font size="+1">Graham,<br>
<br>
The new nodes (88 bought by Physics, 16 bought by
IT, total 104) are dual Intel E5-2670v3 (Haswell)
12 core, 2.3 GHz. Each node has 32 GB DDR4-2133
memory. <br>
<br>
The IT portion is intended to compensate Physics
and LQCD for expected outages during the coming
year as power and cooling are upgraded. <br>
<br>
GlueX testing indicates that 2.3 GHz Haswell cores
are 50% faster than the Sandy Bridge / Ivy Bridge
cores already in the farm (as measured by
events/sec/core on an 18 core part also at 2.3
GHz, with more memory per core). That system
scaled linearly through all 18 cores, so there
will be no memory bandwidth bottlenecks at a mere
12 cores per CPU.<br>
<br>
This will be the leanest memory configuration in
the farm (less than 1 GB per job slot on serial
jobs), but we will try to run this with as many
slots as experience shows it can handle (based
upon statistical measurements in actual running).
<br>
<br>
Delivery expected late October, so production
running by Thanksgiving at the latest. More than
half of the increase in capacity will be loaned to
LQCD to build up a positive balance that can be
drawn down in the second half of the fiscal year.<br>

<pre>Hi Chip,
just to be sure that I have the numbers right could you email the specifications of the new nodes? Specifically how many processors per node, the number of cores per processor and processor clock.
Thanks,
Graham
