CLOUD Data Acquisition & Computing services

The CLOUD Data Acquisition & Computing services are designed to provide data, meta-data and instrument computing integration at running time and optimized access to the cloud raw and processed data at all times.

1 Outside CERN or on the CERN network (wireless and cable)

1.1 Software access (NEW)

The Aeroplot data plotting and data access tool.

1.2 Cloud@U.Lisboa mirror:

1.3 In the CLOUD wired private LAN

2 DAQ/Documentation Service

3 CLOUD extended abstract list

4 CLOUD 8 planning

Table 1 Subsystems or instruments in CLOUD
The main tasks defined previously, can help generalize the communications with the subsystems. All the systems have updated files as data storage, some are ASCII and some are binary files, implying that the DAQ must be able to store data that are fetched from files made available by the different CLOUD subsystems.
