The PARADOX cluster (“PARADOX”) is a common name for high-performance computer equipment hosted by the Scientific Computing Laboratory, Center for the Study of Complex Systems of the Institute of Physics Belgrade, Pregrevica 118, 11080 Belgrade, Serbia. This document defines conditions under which the use of PARADOX is offered to the users. Therefore, all users should read, understand, and accept these terms when requesting an account, and abide by these policies when accessing PARADOX.
The use of PARADOX is provided to users without any warranty. The Institute of Physics Belgrade will not be held liable in the event of any system failure or data loss or corruption for any reason including, but not limited to: negligence, malicious action, accidental loss, software errors, hardware failures, network losses, or inadequate configuration of any computing resource or ancillary system.
At the moment, PARADOX equipment is organized into four main logical units:
The terms described in this document apply to all PARADOX units.
Usage of PARADOX is subject to the PARADOX cluster acceptable use policy.
For information on the processing of personal data of users which is carried out via PARADOX, please see the PARADOX cluster privacy policy.
The PARADOX cluster operational team try to plan and inform users of cluster maintenance (via e-mail announcements), however the cluster may require shutting down without prior notice in case of a power outage, emergency, or unavoidable maintenance.
In rare instances, unforeseen circumstances may cause job failures or require suspending or even killing jobs without warning. Users are strongly urged to make use of checkpointing or other standard programming practices to allow for this possibility. Wall clock completion times are considered when downtimes are scheduled. If the job is not expected to complete before the outage begins then the job will not run.
Researchers who publish results obtained using the PARADOX cluster should include an acknowledgement in any publications that result from that work. This includes journal articles, presentations, reports, proceedings and book chapters. Please use the following text:
“(A part of) this research was performed using the PARADOX supercomputing facility at the Scientific Computing Laboratory, Center for the Study of Complex Systems of the Institute of Physics Belgrade.”
If you have any questions about this privacy policy, please contact us by e-mail: paradox@ipb.ac.rs.
The PARADOX cluster terms of use will be amended and reviewed periodically, and the Scientific Computing Laboratory, Center for the Study of Complex Systems of the Institute of Physics Belgrade reserve the right to modify and update the present terms whenever deemed necessary, whereas any changes shall become effective after publication on the http://www.scl.rs/PARADOX_User_Guide/policies/terms-of-use.html.
