 ## Advanced Job Placement
 
-### Placement by Name
-
-Specific nodes may be allocated via PBS:
-
-```console
-$ qsub -A OPEN-0-0 -q qprod -l select=1:host=cn120+1:host=cn121 -I
-```
-
-In this example, we allocate the nodes cn120 and cn121, (number of cores depends on the cluster), for 24 hours. Consumed resources will be accounted to the Project identified by Project ID `OPEN-0-0`. The resources will be available interactively.

 ### Salomon - Placement by Network Location
 
 The network location of allocated nodes in the [InfiniBand network][3] influences efficiency of network communication between nodes of job. Nodes on the same InfiniBand switch communicate faster with lower latency than distant nodes. To improve communication efficiency of jobs, PBS scheduler on Salomon is configured to allocate nodes (from currently available resources), which are as close as possible in the network topology.

-### Salomon - Placement by Specific InfiniBand Switch
-
-!!! note
-    Not useful for ordinary computing, suitable for testing and management tasks.
-
-Nodes directly connected to the specific InfiniBand switch can be selected using the PBS resource attribute `switch`.
-
-In this example, we request all 9 nodes directly connected to the r4i1s0sw1 switch.
-
-```console
-$ qsub -A OPEN-0-0 -q qprod -l select=9:switch=r4i1s0sw1 ./myjob

-### Salomon - Placement by Hypercube Dimension
-
-Nodes located in the same dimension group may be allocated using node grouping on the PBS resource attribute `ehc\_[1-7]d`.
-
-| Hypercube dimension | node_group_key | #nodes per group |
-| ------------------- | -------------- | ---------------- |
-| 1D                  | ehc_1d         | 18               |
-| 2D                  | ehc_2d         | 36               |
-| 3D                  | ehc_3d         | 72               |
-| 4D                  | ehc_4d         | 144              |
-| 5D                  | ehc_5d         | 144, 288         |
-| 6D                  | ehc_6d         | 432, 576         |
-| 7D                  | ehc_7d         | all              |
-
-In this example, we allocate 16 nodes in the same [hypercube dimension][5] 1 group.
