I work for one of my professors and we are trying to run SU2 in parallel on a cluster owned by the university that uses slurm for its workload manager. The problem we are running into is that when we ssh into the cluster and run the command:
Code:
parallel_computation.py -f SU2.cfg
on an assigned node by slurm (using sbatch), the code hangs and wont run. The weird thing about this is if we run the same command on the login node, it works just fine. Do any of you know what could possibly be the problem?
Here is some additional information:
- We talked with the IT guy in charge of the cluster and he doesn't have enough background to know what is going on.
- On some of our output files we would get the escape key [!0134h, when we changed the terminal settings to get rid of the escape key the code behavior was consistent as above.
- We can run SU2_CFD "config file", the code in serial, on both the login node and the cluster just fine
- We have tried running an interactive session on a node (using srun), no change in behavior
Any thoughts would be appreciated! We really want to be able to run the code in-house instead of outsource.

Hello,
Under ksh I have to run a script on one of the nodes of a Solaris 8 cluster which at some time must execute a command on the alternate node:

Hi,
Is it possible to have a Solaris cluster of 2 nodes at SITE-A using SVM and creating metaset using say 2 LUNs (on SAN). Then replicating these 2 LUNs to remote site SITE-B via storage based replication and then using these LUNs by importing them as a metaset on a server at SITE-B which is... (0 Replies)
Setting up HACMP 6.1 on a two node cluster. The other node works fine and can start properly on STABLE state (VGs varied, FS mounted, Service IP aliased). However, the other node is always stuck on ST_JOINING state. Its taking forever and you can't stop the cluster as well or recover from script... (2 Replies)

clinfo
clinfo(1M) System Administration Commands clinfo(1M)NAME
clinfo - display cluster information
SYNOPSIS
clinfo [-nh]
DESCRIPTION
The clinfo command displays cluster configuration information about the node from which the command is executed.
Without arguments, clinfo returns an exit status of 0 if the node is configured and booted as part of a cluster. Otherwise, clinfo returns
an exit status of 1.
OPTIONS
The following options are supported:
-h Displays the highest node number allowed to be configured. This is different from the maximum number of nodes supported in a given
cluster. The current highest configured node number can change immediately after the command returns since new nodes can be dynam-
ically added to a running cluster.
For example, clinfo -h might return 64, meaning that the highest number you can use to identify a node is 64. See the Sun Cluster
3.0 System Administration Guide for a description of utilities you can use to determine the number of nodes in a cluster.
-n Prints the number of the node from which clinfo is executed.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
This is usually because the node is not configured or booted as part of a cluster.
