This guide illustrates how to submit a FLUKA parametric job using IGP (Italian Grid Portal)
 

Preliminary Steps

It is mandatory a valid X509 certificate and VO GRIDIT membership. We assume that you are familiar with concepts like certificate proxies, job submission, storage elements. If this is not the case, better read this introduction. Other than that, you don't need to access an User Interface, since your grid interactions will be performed through IGP. Of course you will need to be registered to it. Each portal user has a personal storage area, accessed through IGP Data Management (DM). The storage area path has a common prefix (/grid/gridit/spes_project/fluka) and a suffix depending from the user name (/username). Users might create directory and files under this path.

If this is not the case, better read this introduction. Other than that, you don't need to access an User Interface, since your grid interactions will be performed through IGP. Of course you will need to be registered to IGP, and authorized to the usage of FLUKA : this is done sending a mail to igi-portal-admin at lists.italiangrid.it, putting in copy alberto.andrighetto at lnl.infn.it.

Input files

 This personal storage area will be used to load input files, using an archive, either plain (extension tar) or compressed (extension will be tgz). The archive must necessarily contain FLUKA input files, according to the following convention: archiveName_N.inp with N positive integer. FLUKA input files have also to be consecutive within the same archive. For instance, if your archive is called silicon2, the archive should be looking as follows:
Line: 34 to 35
  Please make sure that the chosen archive name (silicon2 in the example above) is the same for each inp file, and it corresponds also to the archive file name.

Login to IGP

Once you login to IGP, you are directed to the welcome section.

From 'My Data' you can manage your personal data. From there, with 'Advanced Settings', you can modify some settings related to notifications and proxy regeneration. It is suggested to enable Proxy Notification, which informs you when your proxy is going to expire, and to set Proxy Lifetime to 7 days.

FLUKA first access

Each portal user has a personal storage area, accessed through IGP Data Management (DM). The storage area path has a common prefix (/grid/gridit/spes_project/fluka) and a suffix depending from the user name (/username). The suffix depending from the username must be formed in this way : first given name character+family name. For instance, if the user is 'Mario Rossi', username will be mrossi. In case of repeated names, they will be differentiated with a further, randomly generated, suffix. Users might create directory and files under their own area, where there is no limit for the number of subdirectories. Following the first access to FLUKA, in IGP, the user must select his home directory LFC Home Folder, or create it if not existing. Although it's possible to change it, it's warmly suggested to leave unchanged LFC Home Folder once it has been defined.

Once that first access procedure is done, the user is redirected to Job Management area

Input file upload

 Once created locally (on your own machine) the archive with the input files, you can upload it to IGP, with the DM tools accessible in the Storage section. Change current path to the common /grid/gridit/spes_project/fluka and then to the personal directory within. If the input directory does not exist, create it. Then click on Upload, which prompts for the archive file selection. As target, you can leave Random Destination, or select a Storage Element you trust. Then press start to trigger the transfer, and wait for the Transfer OK message.
