Remote components in sciCoDE
In many cases the user want to execute his code on remote machines (e.g. run a simulation on a supercomputer). sciCoDE provides a way to create remote components.
The C++ remote code
If you want to use your C++ application inside sciCoDE as remote component you should generate some stubs needed to establish the connection between the core of sciCoDE and your component. One of the communication methods provided by sciCoDE is a file-based protocol, which can be used on arbitrary systems connected through SSH and SFTP. The SSH implementation is based on the library. As previously described the components in sciCoDE are specified through a simplified version of SIDL. Only four data types are allowed : strings, doubles, longs and booleans. This types can be used as in, inout and array parameters. This simplification makes the implementation of communication protocols much more easier. The most important part of the SIDL specification are the interfaces ,which are mapped to ports. In the file-based protocol each port is represented through component-specific folder
on the file system. The following example should illustrate this:
The following steps are needed to prepare you C++ code:
