Users views

The following snapshots illustrate a typical interactive session a user could have using the web interface.

Different browsers on different operating systems may have different presentations of the same page.

First, under the heading "Web session", login by providing your ECMWF user identifier and your passcode. You may modify the default value of 30 minutes to a greater value, if you plan to use the service with breaks of more than 30 minutes.

Once authenticated, your browser is redirected to the main page containing the menu described in the previous section (the default option is "Browsing > ECHOME files"). To browse other directories from your home directory, select a target directory and press the "Browse" button.

To download a file from your current directory (./gribex in this case), click the transfer icon of the target file in the list. To upload a file into your current directory select the Üpload files" option and click the Ï want to" button.

Click the "Browse" button and select the file (E:\fortran.txt) you want to upload to your current directory (you may repeat the operation three times if you want to transfer more than one file). Then click the "Upload local files to your target directory".

Once uploaded, a summary is printed to inform you of the size of the files uploaded. You may click the "Browse uploaded files" to return to your current directory (where your files have been uploaded).

You can see the "fortran.txt" file is now stored in your current directory. You can continue browsing directories and repeat the operation as many times as you need. To submit a job, you should first choose which system at ECMWF you want to use. To have a list of the systems at ECMWF supporting a batch service, click the "Browse queues" button.

The queues shown are known as ECaccess queues. For each of these ECaccess queues, you can click on the "show details" icon to see its associated batch queues on the system at ECMWF, e.g. below for the ECaccess queue hpcd:

To submit a new job, select the "Submit new job" option in the "Queues/Jobs" menu.

You may enter your script in the text area provided or select a script from your computer. Select the target queue ("hpcd" in this case). Note that the batch queue (or class) and other batch directives have to be included in your script. Alternatively, you can inform ECaccess that your script does not contain batch directives. In this case, default values will be used and ECaccess will fully manage your submission. Once your script is read, click the "Submit job" button to send your request to the server.

The list of notifications allows you to attach your job to one event in the ECMWF operational suite. Please refer to the Web page on submission of time critical jobs for further details.

Once the job is submitted, a summary screen gives you the job identifier number of your new job request. It can be used to reference the submitted job using the monitoring interface (described in the next section). If you want to arrange a secure file transfer of the result, click the "Transfer with Ectrans after execution" button.

If required, modify the default values (gateway name, user identifier) and specify the erase option of the secure file transfer (erase option is discussed in section 4.2). Then click the "Send file(s) to your target host" to proceed.

Once it is spooled, a summary screen gives you the copy identifier number of your new transfer request. It can be used to reference the secure file transfer using the monitoring interface (described in the next section.
