Preparing a GRID for the Stock Analysis Application

by Ezio Corso last modified 2008-01-18 12:01

Summary of the configuration steps that allow the Stock Analysis Application to be run in a GRID infrastructure different from EUINDIA.

Ask the GRID software manager to install the software in the following way; in each CE where you want to run the application (presumably all of the GRID), do the following:


(0) Software installation:

Fetch the prepared tar file from: http://euindia.ictp.it/stock-analysis-application/JDK1.6.tar.bz2/view

In the CE's experiment_software_directory create a subdirectory called JDK16

Inside JDK16 simply untar the file with tar -xjvf JDK1.6.tar.bz2

Take a note of the name of the directory if it is not JDK16, as it is needed by the Stock Analysis Software.

Moreover, notice that the tar file has been prepared for convenience only. Should the Software Manager prefer, a JVM  version 6 may be installed using the files directly from the vendor's site and following their installation instructions.


(1) Publish the GRID software tag according to VO usage:

For example in euindia it is VO-euindia-JDK16. Take a note of the tag name, as it is needed by the Stock Analysis Software.


(2) Ask the GRID authority about the name of the environment variable for experiment_software_directory:

For example in euindia it is $VO_EUINDIA_SW_DIR. Take a note of it, as it is needed by the Stock Analysis Software.



As usual in European GRIDS, I assume all sites have the same software_directory environment variable name, all publish the same chosen tag, and the chosen subdirectory name (JDK16) is the same for all. As a last step, remember to setup a storage element for the data:


(3) Temporary controlled access storage solution:

You must have an agreement with a Site you trust, since the local system administrator will have to make simple albeit non-standard changes; moreover, you must trust the site since this solution does not stop the system administrator from stealing your data.

Have a calssic SE available with GridFTP: make sure it has enough room for your data (ask for 1TB or 2TB). Map Spyros' DN (and yours) to a specific local User account. Have a directory in the SE where only that User has access, while Group and Other are denied all operations.

Take note of the full URL to this directory, as it is needed by the Stock Analysis Software.
