In our previous entry we made a demo tour of our Deci
It lets you create an IBM ID if you don't have one. Assuming you have got one, we move to the next page by clicking on the Already have an IBM id? link.
Enter your IBM Id, then submit. This should send you an activation email to the adress you used when creating your IBM ID. Check for you mailbox. If you do not see the email within few minutes, check for you spam directory as some spam filters may be too aggressive. If you have any issues, click the following link to get help: http
Note that you are signing up for a trial as a guest and as such, your data will not be retained after your trial period has expired. This no-cost trial is designed to provide you the opportunity to try the full service, before your purchase. Prior to starting a trial, if you know you would like to retain your data, contact your IBM sales representative for a customized pilot subscription.
Clicking on the activation link in the email that was sent to you moves you to an authentication page. Enter your credentials, i.e. your IBM ID and the associated password to log in. Once logged in you get to a very simple interface
You can then drag and drop a file from your local machine to the gray area, or click on that gray area to open a classical file browser window.
Let's use drag and drop for the fun of it:
As soon as we drop the file, upload begins.
Then solve begins. If our server is too loaded you may get a pending message. It indicates that your solve is put in our queue. We designed that queue to be extremely reliable in order to ensure that your job will be executed eventually.
Solve then starts automatically
You can click on the info tab to get information about the problem you are solving. You don't need to wait for completion of the solve job to see that information.
once the job is completed you can retrieve the results stored in a CPLEX solution file by clicking on the Results tab. You can then use that file exactly as you would do with any CPLEX solution file.
You can also look at CPLEX log by clicking on the Log tab. This displayed the last lines of the log.
You can then download the full log or display it in a separate browser window by clicking on one of the bottom buttons.
We currently support .lp, .mps, and .sav files for CPLEX input. Let us solve one problem in each format. Interestingly enough, when we drop the third file the drop zone displays a warning. We cannot have more than three solve at once.
In order to be able to solve another problem we first need to make room by deleting an existing solve. If the solve we want to delete is still running, then we must abort it using the right button on the solve row. Once aborted, or if the solve is already complete, we can download the information we are interested in, then delete the solve by clicking on the button with a cross at the right. The drop zone is available again.
This concludes our walk through with CPLEX on cloud. Please use the "Contact Us" tab on the left pane to report issues and to provide feedback. This trial is for you, and your feedback is key to make sure we will deliver a service that suits your needs.
We look at OPL on cloud in our next blog entry.
