Computation Server (CS)

There are two Computation Servers (CS) available for data analysis through remote access. One Windows operated CS (WCS) and the other one with Linux (LCS). In addition, you can mount your own storage media (hard drive, USB disk, etc) to link with a CS. This way all the calculations will be made by a remote server and you can continue your work by using your own laptop/desktop. Access to a CS can be requested by using the form below.

Please note that a Computation Server (CS) should only be used to store data temporarily while it is being processed. After completing the analysis all data should be moved to a more suitable location.

We do not have any back-ups for the CS, so lost data cannot be recovered!
