Computer Services Policy

When you reach the DIPC, the Foundation assigns you a personal computer where you can install the operating system that you want (or ask the System Manager to install it), and from where you will be able to access the computational resources sited at the DIPC using a computing account that the Computer Center creates for you. There are several researcher groups at DIPC using these computational resources. Please respect the other system users and thereby help to make this a friendly computer environment. IMPORTANT: if you want to install the operating system by yourself, note that each DIPC personal computer has a specific IP address assigned, and only one. If you do not know this address or you do not know how to set it, please DO NOT TRY to install the operating system, because you could cause very serious communication problems. In general, take a look at this link to know the services that the Computer Center offers and how to ask for them.

  • TORQUE Resource Manager

    All the computational resources at DIPC have a queue system installed, TORQUE (Terascale Open-Source Resource and QUEue Manager), and a job scheduler system, MAUI. Do not execute jobs interactively on any node outside the queue system (that is, without the "qsub" command). Violation of this policy will result in your jobs being automatically aborted without previous warning. TORQUE and MAUI handbooks including main commands can be found here.

  • Edition, compilation and execution

    There are several clusters at DIPC. Please, use them as specified in this link. In summary, you have some machines where you can edit and compile your program and then send it to the queue system, access computers, but where you shouldn't try to execute the program interactively. Please read the content of the link above carefully, because you could lose the results of a running program if you send a job incorrectly.

    Each cluster has an Access Computer or AC. Please, take a look at the handbook of the desired cluster in order to know its AC's. It is not possible to establish a ssh session from your computer to the AC directly for security reasons. A ssh connection to the ac-02.sw.ehu.es machine has to be established first. From this machine all the ACs are reachable.

  • Limits

    There are dynamic limits on then number of cores and the amount of data a researcher can store at scratch and home directories. A job will remain queued when a researcher exceeds the maximum number of cores per user, or when there are not enough resources available. In the first case, it will be necessary to wait until any of the researcher's running jobs finish. In addition to this, each researcher has an annual limit of "computational units" that takes into account the computational time, memory and disk consumption. More information about this annual limit and disk quotas can be found here.

  • Software

    If you want to install software in the scratch or home directories of the DIPC clusters but you don't know how to do it, send an email to the This email address is being protected from spambots. You need JavaScript enabled to view it. . It is possible to install all the software you are interested in on the personal computer assigned by the DIPC as long as it is NOT pirated software. Find the list of the software installed on our clusters here and the software available for users here.

  • Disk use

    Two kind of disk directories are available for your jobs: the home directory located at /dipc that is intended for permanent files storage, and the /scratch and /lscratch directories that are only intended for executions. The home directory is automatically backed up daily to prevent data loss in case of disk failure. However, there are not backups of /scratch and /lscratch directories, so if any disk fails YOU COULD LOSE FILES. Please, REMOVE temporal files from /scratch and /lscratch directories and MOVE files not longer needed for current executions to your home directory.

    The computing account holder undertakes not to store illicit files, private data and, in general, any data that is not related to his or her research in the home directory or web server directory.

  • DIPC Personal Computer hardware and personal data

    DO NOT TRY TO INSTALL INTERNAL HARDWARE such as disks, memory, etc in the assigned personal computer. Ask the This email address is being protected from spambots. You need JavaScript enabled to view it.  for help in case you need to install additional hardware. Take into account that you have to copy all the data stored at your personal computer when leaving the DIPC. It could be reinstalled if the next user using the computer asks for a different operating system or if there is not enough space for working. Please do not change root or administrator passwords. It could delay the reconfiguration of the computer for the new researcher. 

  • Virus

    An antivirus is installed on every personal computer at DIPC. It is automatically updated every time a new virus arises. Sometimes the antivirus can not avoid the infection when the operating system is not up to date too. Please, contact the This email address is being protected from spambots. You need JavaScript enabled to view it.  to know how to do it, and do not forget to update it frequently. In addition to this, any account created in your computer without password or with a too simple password involve security risks. Please, use complex passwords with letters, upper and lower case, numbers and symbols mixed. 

  • Internet connection

    It is advisable not to use any program that shares movies or music files with other computers through the Internet, as not only the global network could be slowed down, but the PC itself too. If you suspect a program of this nature is installed on your computer but you do not know how to remove it, please contact the This email address is being protected from spambots. You need JavaScript enabled to view it. .

  • Problems

    If you have compilation issues, please read the FAQs files or contact the This email address is being protected from spambots. You need JavaScript enabled to view it. . If the problem is related to a job execution, make sure you are sending it to the queue system as specified in this link. Please contact the This email address is being protected from spambots. You need JavaScript enabled to view it.  when you think you are submitting jobs correctly but you continue having problems. In case you need an IP address or you have network problems, connection to the Internet or clusters, contact the This email address is being protected from spambots. You need JavaScript enabled to view it. . Contact the This email address is being protected from spambots. You need JavaScript enabled to view it. for any other question or problem.
