Programming Environment

The software environment on Ela is controlled using the modules framework, which gives an easy and flexible mechanism to access simple tools only, since you should not build any code on the system.

In fact, no programming environment is provided on the frontend. You can get information on a specific module using the following commands (in the example below, change <module> with the module name):


		
			

$ module avail <module>
$ module show <module>
$ module help <module>

Network

The system is connected through high-speed interconnects to the different filesystems available (GPFS, file transfer, etc…).

File Systems

The shared storage under /project and /store is available through the high speed interconnect.

Please carefully read the general information on filesystems at CSCS.
