I am new to cluster commands. But I have tried utilizing: -pe, but I do not know my parallel computing environment. We are running SGE, is there a simpler command to request more nodes?
first off, i am new to unix so please bear with me. i was reading somewhere that if your i-nodes get critical that it can slow your network down. what are i-nodes and when do they become a critical number? this is what mine states:

Does anyone know something about this? I have no idea what it means and how to do it. but if anyone can give me and explanation and also point me to a website, i'd really appreciate it (5 Replies)

hello Gurus,
My current set up is 3 to 1 Cluster (SUN Cluster 3.2) running oracle database. Task is to reboot the servers. My query is about the procedure to do the same.
My understanding is suspend the databases to avoid switchover. Then execute the command scshutdown to down the cluster... (4 Replies)

Hi,
A customer I'm supporting once upon a time broke their 2 cluster node database servers so they could use the 2nd standby node for something else. Now sometime later they want to bring the 2nd node back into the cluster for resilance. Problem is there are now 3 VG's that have been set-up... (1 Reply)
Hi folks.
I've been a developer for far too many years, but know very little of unix. I have setup a very inexpensive cluster of 6 raspberry pi nodes so I can play around with multi node programming. This is only for fun, but I want to learn properly, else what's the point?!
Setup can be a... (4 Replies)

IPCLUSTER(1)IPCLUSTER(1)NAME
ipcluster - IPython parallel computing cluster control tool
SYNOPSIS
ipcluster {piexec,local,mpirun,pbs,ssh} [options]
DESCRIPTION
ipcluster is a control tool for IPython's parallel computing functions.
IPython cluster startup. This starts a controller and engines using various approaches. Use the IPYTHONDIR environment variable to change
your IPython directory from the default of .ipython or _ipython. The log and security subdirectories of your IPython directory will be used
by this script for log files and security files.
POSITIONAL ARGUMENTS
The first positional argument should be one of: {mpiexec, local, mpirun, pbs, ssh}, which are the available cluster types.
For detailed help on each, type "ipcluster TYPE --help". Briefly:
local run a local cluster
mpirun run a cluster using mpirun (mpiexec also works)
mpiexec run a cluster using mpiexec (mpirun also works)
pbs run a pbs cluster
ssh run a cluster using ssh, should have ssh-keys setup
OPTIONS -h, --help
show help message and exit
EXAMPLE
ipcluster local -n 4
This command will start 4 IPython engines on the local computer.

ipcluster is a tool that ships with IPython, created by the IPython Development Team.
