System Requirements

Sun's® Java Runtime Environment
As the size of your uploade may easily exceed 100 Mbyte, we decided to use Sun's® Java Runtime Environment to provide data compression and a secure file transfer to our server.

Click here to get to the Sun® download page. There click Download J2SE JRE and follow the instructions of Sun's website. You will have to restart your web browser after installing the JRE.

You may need administrator rights to install J2SE JRE onto your computer. Please do contact your system administrator for assistance. If you or your system administrator needs any support please contact us.

Bandwidth
As mentioned above the size of your data files may easily exceed 100 Mbyte. Transferring these huge amounts of data requires bandwidth and time. Listed below are optimistic estimates for a 200 MByte data file:

A-DSL(128 kBit/sec upstream)3.5 hours
A-DSL(192 kBit/sec upstream)2.3 hours
T1(1.54 Mbit/sec )17.3 minutes

Your spectrum files may be compressed significantly depending on the storage format thus reducing the required upload time.

Hardware
We recommend using no less than a Pentium III (or equivalent) for uploading raw data in order to keep the time for file compression at a decent level.
