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:

I have to implement this script on all the clusters of my company (a lot of...).

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)

scversions
scversions(1M) System Administration Commands scversions(1M)NAME
scversions - Sun Cluster version management
SYNOPSIS
scversions [-c]
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The scversions command commits the cluster to a new level of functionality after a rolling-upgrade to new Sun Cluster software. With no
arguments, the scversions command prints a message indicating whether a commitment is needed.
OPERANDS
The following operands are supported:
-c Commit the set of nodes that are currently active members of the cluster to the highest possible level of functionality.
When you upgrade a node (either through upgrade to a new release of the product or by application of a patch) and boot it back
into the cluster, some of the internal protocols on that node might have to run at lower versions in order to cooperate cor-
rectly with other nodes in the cluster. When the cluster is in this state, some administrative actions might be disabled and
some new functionality introduced in the upgrade might be unavailable.
When you run this command once from any node after all nodes are upgraded, the cluster switches to the highest versions of
internal protocols possible. Assuming that all nodes have the same Sun Cluster software installed at that time, all new func-
tionality becomes available and any administrative restrictions are removed.
If a node that has not been upgraded is an active member of the cluster at the time you run the -c option to scversions, the
command has no effect because the cluster is already running at the highest possible level of functionality.
If a node has not been upgraded and is not an active member of the cluster when you run the -c option to scversions (for exam-
ple, if that node is down for maintenance), the internal protocols of the cluster are upgraded to the highest possible ver-
sions. You might have to upgrade the node that was not an active member of the cluster to enable it to rejoin the cluster.
EXIT STATUS
0 Success
non-zero Failure
