In the previous days we performed a complete upgrade of our beloved cluster.
This was necessary as our installation was old and many errors were
present (mainly the recurrent problems with the filesystem).
Most of the cluster is back online (with the major exception of c1
nodes and some c3 nodes). Of course, since everything is new, there
might be some problems to iron out in these first days. Let us know if
you have problems.
Here is a list of the updates:
* We switched from 32 to 64 bits.
Remember to recompile everything, old (32 bits) executables will not work.
Recompiling everything includes deleting every files produced during
the compilation process, otherwise you may still use some old ones. In
other words, remember to “make clean” before “make”. In Argos you need
to execute “build_simulation_framework.sh clean”
* The Linux OS is now Rocks Cluster 6.0, based on CentOS 6.3, if you
need to mention it on some papers. You may see on internet that Rocks
6.0 is based on CentOS 6.2, but we upgraded our system further.
* The packages installed have been cleaned a bit. We took the occasion
to not re-install some packages that we believed were not required
anymore: we prefer to manage a system as clean as possible!
If you miss something that you really need, see this page:
Remember that you can see the list of all packages installed (on the
compute nodes) here:
Do not hesitate to ask if you have any further question.
Expect some (small) issues at the beginning, the contrary would be surprising!
Ah! And we managed to keep all your data. :-)
Have a nice week,
the cluster team.
