-# Gordon Bell and HPL runs 2025
-
-For Gordon Bell and HPL runs in March-April 2025, CSCS has expanded Santis to 1333 nodes (12 cabinets).
-
-For the runs, CSCS has applied some updates and changes that aim to improve performance and scaling scale, particularly for NCCL.
-If you are already familiar with running on Daint, you might have to make some small changes to your current job scripts and parameters, which will be documented here.
-
-## Santis
-
-### Connecting
-
-Connecting to Santis via SSH is the same as for Daint and Clariden, see the [ssh guide][ref-ssh] for more information.
-
-Add the following to your [SSH configuration][ref-ssh-config] to enable you to directly connect to Santis using `ssh santis`.
-```
-Host santis
-    HostName santis.alps.cscs.ch
-    ProxyJump ela
-# change cscsusername to your CSCS username
-    User cscsusername
-    IdentityFile ~/.ssh/cscs-key
-    IdentitiesOnly yes
-```
-
-### Reservations
-
-The `normal` partition is used with no reservation, which means that that jobs can be submittied without `--partition` and `--reservation` flags.
-
-Timeline:
-
-1. Friday 4th April:
-    * HPE finish HPL runs at 10:30am
-    * CSCS performs testing on the reconfigured system for ~1 hour on the `GB_TESTING_2` reservation
-    * The reservation is removed and all GB teams have access to test and tune applications.
-2. Monday 7th April:
-    * at 4pm the runs will start for the first team
-
-!!! note
-    There will be no special reservation during the open testing and tuning between Friday and Monday.
-
-### Storage
-
-Your data sets from Daint are available on Santis
-
-* the same Home is shared between Daint, Clariden and Santis
-* the same Scratch is mounted on both Santis and Daint
-* Store/Project are also mounted.
-
-## Low Noise Mode
-
-!!! note
-    Low noise mode has been relaxed, so the previous requirement that you set `OMP_PLACES` and `OMP_PROC_BIND` no longer applies.
-    One core per module is still reserved for system processes.
-    
-Santis uses low noise mode, which reserves one core per Grace-Hopper module (i.e. per 72 cores) for system processes.
-This mode is intended to reduce performance variability caused by system processes interfering with application threads and processes.
-This means that SLURM job scripts must be updated to account for the reserved cores.
-
-### SLURM
-
-!!! warning "Unable to allocate resources: Requested node configuration is not available"
-    If you try to use all 72 cores on each socket, SLURM will give a hard error, because only 71 are available:
-
-    ```console
-    # try to run 4 ranks per node, with 72 cores each
-    $ srun -n4 -N1 -c72 ./build/affinity.mpi
-    srun: error: Unable to allocate resources: Requested node configuration is not available
-    ```
-
-Explicitly set the number of cores per task using the `--cpus-per-task/-c` flag, e.g.:
-```
-#SBATCH --cpus-per-task=64
-```
-or
-```
-srun -N1 -n4 -c71 ...
-```
-
-## NCCL
-
-!!! todo
-    write a guide on which versions to use, environment variables to set, etc.
-
-See [the container engine documentation][ref-ce-aws-ofi-hook] for information on using NCCL in containers.
-The [NCCL][ref-communication-nccl] contains general information on configuring NCCL.
-This information is especially important when using uenvs, as the environment variables are not set automatically.
