Additional Executables on GF12-GF19

SVN, several Java versions, and other executables are installed on gf12-gf19.ucs.indiana.edu under the directory /globalhome/globalbin. The simplest way to add all of these to your path is to use the command

export PATH=`echo \`find /globalhome/globalbin/ -name bin\`|tr ' ' ':'`:$PATH

or add this to your .bashrc to add all of the additional binary installations. Note ` is a back-tick, on the same key as the ~.

[Fwd: Phishing Email Not From UITS]

Subject: Phishing Email Not From UITS

Colleagues,

You may have recently seen or had users with email purportedly coming from the IU Webmail Team that asks to reply and include your password. These messages have a subject similar to "Confirm Your Email Address!" and have a from address of support@indiana.edu (where the reply-to address is something completely different). They have been confirmed as a phishing attempt and are definitely not from any group at UITS. In fact, UITS will never ask any user for a password via email, in person, or over the phone.

If you or a user mistakenly sent any personal information in reply to these messages, you should immediately change your password at https://passphrase.iu.edu. Any user may also confidentially contact the Policy Office as well [1]. Notices have been posted on IT Notices [2], UITS News [3], and both Webmail and Outlook Web Access login pages [4].

For more information on phishing and tips on avoiding these scams, visit the KB article http://kb.iu.edu/data/arsf.html. If you have any further questions, feel free to ask.

Thank you,
LSP Services

Lab Presentation November 16

Yili Gong will give a practice presentation for the coming PDCS'07.

Title: Matchmaking Scientific Workflows in Grid Environments
Time: 2:00 - 3:00 pm, Nov. 16, Friday
Venue: Room 100B, Showers Complex
Abstract:
In this paper we analyze the scientific workflow matchmaking problem in Grid environments and combine workflow mapping and scheduling. Based on the characteristics of Grids, a new resource model is proposed. Motivated by the observations that not all jobs can run on all resources and that resource-critical jobs should be considered with their ancestor and descendant jobs when mapping, a novel resource-critical algorithm is designed based on a new Grid resource model. By means of experiments, it is shown to have good performance.

gf3 reboot issues

Gf3's network interface does not get started properly on reboot, so this had to be done manually today. This also requires manually mounting NFS directories and manually restarting sshd.

Should find a fix for this.

Grids Network Issues

Grids has been bogging down with excessive ssh and httpd connections, so I temporarily shutdown both of these to clean out the connections. I also killed all of the sshd connections (most of which should not have been kept alive).

I also changed a few parameters in the Apache httpd.conf file to make connections time out more quickly (from 5 hours to 5 minutes). This should not affect anyone unless you are, for example, downloading a large PDF file over a very slow connection from the lab publication list.

[Fwd: Lab presentation at 3:30pm Friday]

Presenter: Ahmet Sayar
Topic : High Performance Federated Service-Oriented Geographic Information Systems
Location : 100B, The Large Conference Room on the first floor
Date : Friday, Octobor 26
Time: 3:30 pm

Backed Up Directories of Lab Servers

The following directories are backed up using rsynch to the SAN drive in room 222:

• grids
• /grids/c2/www/htdocs
• /var/mail
• /grids/c2/webcontent
• gf7
• /usr/local/apache
• /opt/lampp
• /var/lib/mysql
• ripvanwinkle
• /export/home
• gf8
• /home
• gf12
• /globalhome
  

Accounts on GridFarm Machines

Various pieces of random information

• The machines gf1-gf8 and gf12-gf19 have separate account systems and separate file systems for performance reasons.
• Gf8 and gf12 are the head nodes. Update account information here.
• To get machine info, look at the files /proc/cpuinfo, /proc/meminfo, etc.
• To get the specific version of linux, look at /etc/redhat-release.
• Java, SVN, and several other useful things are installed on /globalhome/globalbin on gf12-gf19. To add these to your path en masse, use the command (or add .bashrc)
  
• export PATH=`echo \`find /globalhome/globalbin/ -name bin\`|tr ' ' ':'`:$PATH
• If you need MySQL installed, you can do this yourself. See the second part of the notes at http://communitygrids.blogspot.com/2006/04/installing-second-mysql.html. Use a port other than 3306 (the standard mysql). Use telnet or nestat -a to make sure the port you want to use is available.
