Client–server architecture for a high-throughput Bragg spot analyzer. The illustrated client (a) is a web browser, but the client is usually the beamline component responsible for the raster scan, such as Blu-Ice (McPhillips et al., 2002BB36) or GDA (Aishima et al., 2010BB3), implemented in any language that supports the HTTP protocol. The server (b) is a multicore Linux system running the Apache httpd daemon, which delegates incoming requests to one of 48 parallel child processes, each of which runs Python-language cctbx code mediated by the mod_python package (c). The server returns text-based output identical to that produced by the command-line program distl.signal_strength. There is also an option for the returned text to be formatted in extensible markup language (XML) suitable for automated control-system clients. Full instructions are given at .
