Toolkit 2.4 Install

Will I be able to use the toolkit?
What do I need? Where do I get it?
Installing the Grid Packaging Tool
Installing the Client and SDK packages
Configuration
Installing GSI enabled SSH Client
• Assumed inability to install as root
• Also assumed all commands run in same session
Induction to Grid Computing and the National Grid Service
Will I be able to use the
toolkit?
• The toolkit is opensource.
• The default is for all high numbered available ports to be
used for incoming connections. This can be restricted to
a defined range.
– Range dependent on number of simultaneous running jobs.
More jobs = More Incoming Ports needed.
• Either:
– You are the your firewall administrator, or
– You have a very understanding firewall administrator
• Extremely problematic if on a network using Network
Address Port Translation
– for example behind a home ADSL modem/router.

What do I need?
Where do I get it? (1)
• From http://www.globus.org/gt2.4/download.html
– gpt version 3.0.1 (grid packaging tool)
– All parts of the client binary bundle (globus-all-client2.4.3-i686-pc-linux-gnu-bin.tar.gz)
– All parts of the sdk binary bundle (globus-all-sdk2.4.3-i686-pc-linux-gnu-bin.tar.gz)

Installing into ~/myglobus
Install using gpt
export GLOBUS_LOCATION=~/myglobus
$GPT_LOCATION/sbin/gpt-install globus-allclient-2.4.3-i686-pc-linux-gnu-bin.tar.gz

-nonroot
– Take the default answers and choose “save, configure
the GSI and Quit” when prompted.

Install the sdk package
• $GPT_LOCATION/sbin/gpt-install globus-allsdk-2.4.3-i686-pc-linux-gnu-bin.tar.gz

Configuration: Install UK
CA certificates
• Certificate Authorities are only recognized if their
certificates are found within the correct globus
folder and have the correct names
• Move the certificates to where globus expects
the certificates to be:
– mv 01621954.*
$GLOBUS_LOCATION/share/certificates
– if installing as root this is normally /etc/gridsecurity/certificates/
Induction to Grid Computing and the National Grid Service
Configuration: Runtime
• By default globus expects to be able to receive an
incoming connection on any high numbered available
port.
• The reality is that most sites restrict to use ports 20000 –
25000
• Before running any globus commands type (assuming
running in a new session):
– export GLOBUS_TCP_PORT_RANGE="20000 25000"
– export GLOBUS_LOCATION=~/myglobus
– source $GLOBUS_LOCATION/etc/globus-user-env.sh
• Don’t forget about modifying any firewalls you are
behind.

Installing GSI enabled
SSH
• Check what flavor’s are available (both development and
run time versions)
• $GPT_LOCATION/sbin/gpt-query globus_gssapi_gsi

And Finally ….
… check the integrity of your installation

Network Performance
Tuning
To increase maximum potential networking
performance, adjust system max TCP buffer
• Add the below text to the file /etc/sysctl.conf, and then
run "sysctl -p”
# increase TCP max buffer size
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
# increase Linux autotuning TCP buffer limits
# min, default, and max number of bytes to use
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
