Head or Submit Nodes
Only a few of our machines are directly connected to the internet and from those, only a few are of relevance for a typical user.
As of 2020, we offer the following machines as login nodes - please
add the domain .atlas.aei.uni-hannover.de
to each of the names:
condor1
- Submit machine for HTCondor connected to the main pool

condor8
- Special submit machine for a small pool of AMD machines for use with purely parallel jobs (MPI based) using HTCondor’s dedicated scheduling
- virtual machine with 4 cores and 8 GB RAM
- ssh fingerprint
SHA256:7HvJG0EseAPy6V3NzHyoD4808FgXRiGVnIkjzR7uOFY
condor9
- Special submit machine mostly for interactive jobs or very small test runs. The compute nodes in this pool are mostly unique builds based on hardware of the main pool or specialized builds.
- virtual machine with 2 cores and 2 GB RAM
- ssh fingerprint
SHA256:iM6YNBAr3tX6f+g9UYokGC9cka7dhYWIzTTGPbyE/ns
All submit machines for the main pool are treated equally, i.e. it does not matter on which of these a user submits jobs on.
Additionally, we try to maintain additional head nodes for interactive
work available under the names atlasX.atlas.aei.uni-hannover.de
(where X may run from 1..9 but usually we try to keep the lower digits
online). As these are usually based on older hardware, the
availability may change on short notice if we run out of matching
replacement parts.
These machine usually have more memory and/or CPU cores than the
condor submit nodes and also more scratch disk space available under
/local/user
.
