Leginon

h1. Minimum Requirements for non-frame-saving camera

*We don't recommend using a computer with Windows PC as the second computer as an option*.

h3. CPU

Minimal 4 GHz;

* Python instance of Leginon runs only on one core on the processing server.  If you have multiple core, the rest will only be useful if you want to do other things on it such as using it as the database server, webserver, and basic Appion processing.

h3. RAM

The whole system with its image processing, database query and web serving, needs significant memory.  Realistically, you will need minimal of 4GB memory for all processing+database+web server activities for one microscope operation with 4k camera that serves two persons (one operates the scope, one just look at the images from the web viewers) at the same time.  We know of at least one successful daily usage at this configuration.  For 2k camera, an all-in-one computer with 3GB memory has also been used successfully.  If you are buying a new computer, get at least 6GB memory would be a good idea. 

h3. Display

Pretty much everything today would work for data acquisition. GPU server for frame alignment of DD camera is separated.  See below.

h3. File server

10 GB for the softwares and maybe a few hours worth of data collection. Much largerfor routine use.

h3. Network connection speed

100 Mbps might be possible.
