<p>Folks,</p>
<p><br>
</p>
<p>Note the item quoted below from Bryan last Thursday. This means
that when you log into ifarm today, you are logging into a
different OS than you had when you logged in yesterday. Our
software packages need to distinguish between code built on CentOS
7.2 vs. that built on CentOS 7.7. That means stuff you compiled
yesterday is not suitable for jobs you are running today. On
ifarm, you need to recompile everything that you compile yourself.</p>
<p><br>

<p>Bryan also mentioned:</p>

<p>I think that means that batch farm default for CENTOS7 nodes
changed its default. [Someone should correct me here if that is
incorrect.] Assuming I am right about that, if you choose vanilla
CENTOS7 in your farm jobs, and it worked yesterday, it might not
today if it depends on code you compile yourself, for reasons
similar to those described above.<br>

January 21st the
<i style="font-weight: bold;">ifarm.jlab.org</i> alias will
be pointed to CentOS 7.7 hosts only. ifarm1801 will be
upgraded to CentOS 7.7. After that change, the interactive
farm will consist of ifarm1801 and ifarm1802 running Intel
Skylake processors, and ifarm1901 run AMD Epyc "Rome"
processors. The older ifarm1401 and ifarm1402 systems will
remain at CentOS 7.2 until the farm is completely
transitioned, at which point they will be retired. </span></font></div>
