SeedGendbTgDemo

UserPreferences

There are two main components of the demo: the configuration on the ANL TG nodes, and the configuration on seed-linux-2.

1 Teragrid Configuration

The TG login node is tg-login.uc.teragrid.org.

A PBS startup script for the SGE execution daemon nodes is in /home/olson/SGE/start-nodes-64. This can be submitted to the scheduler with this command

    qsub /home/olson/SGE/start-nodes-64 

This command will return a job number:

    olson@tg-login1:~/SGE> qsub start-nodes-64  
    149749.tg-master.uc.teragrid.org 

For best results (that is, I don't know if it will work if you don't), run the submission as user olson.

Other useful TG commands are pbstop -c 20 to show an updating view of the machine state and the job queue, and qdel #### to remove a job from the queue.

2 seed-linux-1 Configuration

Again, best results will be had by running as user olson.

To initialize the shell environment for running GENDB, SEED, and SGE commands, run this (for bash):

    cd /home/olson/FIGdisk.Sep15 
    source config/fig-user-env.sh 
    cd gendb 
    source SGE/default/common/settings.sh 

To run the GUI SGE tool monitor, set your X11 DISPLAY environment variable appropriately, and run qmon.

For GENDB job submission to work, there is a dispatcher process that should be running. To check if it is, do ps auxww | grep dispatcher. The result should look something like this:

[olson@seed-linux-2 gendb]$ ps auxw|grep dispatcher  
olson     9399  0.0  1.4 32928 15052 ?       S    Nov10   0:02 /home/olson/FIGdisk.Sep15/env/linux-postgres/bin/perl /home/olson/FIGdisk.Sep15/gendb/share/gendb/exec/dispatcher.pl -l dispatch.log 
olson    12792  0.0  0.0  3588  644 pts/0    S    13:56   0:00 grep dispatcher 

To restart the dispatcher if needed:

cd /home/olson/FIGdisk.Sep15/gendb 
bin/dispatcher -l dispatch.log 

The file /home/olson/FIGdisk.Sep15/gendb/dispatch.log holds a log of dispatcher output.

3 SEED info about seed-linux-2

The SEED running here is a little nonstandard; it is using mysql with a web server configured for mod_perl.

To start the seed services, become user olson and run the following:

/home/olson/FIGdisk.Sep15/bin/start-servers 
/home/olson/FIGdisk.Sep15/FIG/bin/start_dbserver 

The web server that is to be run is not the system webserver. To start the right one, run this as root:

/home/olson/apache/bin/apachectl start 

after ensuring the system-installed apache is not running.
