CSTR Computer Support

The CSTR computer network is part of the Informatics DICE network. General Documentation and FAQs concerning DICE can be found here. New users should take the time to read this information.

Specific CSTR information

Printing Posters

The simplest way to print an A0 poster is to use the self-service printers in the main library in George Square.

Desktop Computers

Desktop machines are generally single processors. You can run whatever you like (subject to the University's Computing Regulations, of course) on the machine that you sit at but please do not run processor intensive screen savers or other energy-wasting processes.

Compute cluster

The Edinburgh Compute and Data Facility (ECDF) runs the 'eddie' cluster and a storage area network (SAN). This provides the majority of CSTR's compute needs.

CSTR purchases substantial additional guaranteed capacity. If you want an account, you must request one via the ECDF webpage, first asking your supervisor/PI which project code you should use.

General purpose compute servers

Only members of CSTR can ssh to these machines. There is no job control - simply use 'top' to identify quiet machines.

Multicore & large memory compute servers

Only members of CSTR can ssh to these machines. These machines mount the GPFS filesystem. There is no job control - simply use 'top' to identify quiet machines. It is essential to compile your code against the Intel Math libraries to get good performance out of these machines (including those using AMD CPUs). Currently, the only way to do this is to ask Peter Bell for assistance. If you cannot (or do not want to) compile against the Intel Math library, then please use the general purpose machines above.

GPU servers

CSTR also has a number of dedicated GPU servers on the DICE network. Only members of CSTR can ssh to these machines. Do not run heavy CPU jobs on these machines - use the compute servers listed above. These machines also mount the GPFS filesystem. To use the GPU machines, it is essential to use the gpu_lock mechanism. Ask an experienced user for help before using any of these machines.
