FarmShare consists of several environments. Use the following guide to determine which environment is best suited for your task.
Low-intensity computing (cardinal.stanford.edu)
The cardinal systems are small virtual machines best suited for low intensity tasks including checking email and reading newsgroups, transferring files, or editing web pages. Long-running or compute-intensive jobs found running on these systems may be killed to free system resources for intended tasks; use corn.stanford.edu or barley.stanford.edu for these instead.

3 | VMware | Ubuntu GNU/Linux | 1-core 2.4 GHz Intel Xeon E5620 (equivalent) | 2 GB | 4 GB swap, limited temp |
General-purpose computing (corn.stanford.edu)
The corn systems are well-suited for general, interactive computing including most coursework, development, and other common computing tasks. They are also appropriate for long-running and/or compute- or memory-intensive tasks (e.g., mathematical and statistical analysis, physical simulation, parallel programming).

40 | Sun Blade X6240 | Ubuntu GNU/Linux | 8-core 2.7 GHz AMD Opteron (2384) | 32 GB | 10 GB swap, 75 GB temp |
High-performance computing (barley.stanford.edu)
The barley systems are intended for high-performance, non-interactive, and parallel computing. Like corn systems, barley systems are appropriate for long-running and/or compute- or memory-intensive tasks, but login is not permitted; batch jobs must be submitted from corn.stanford.edu using a queuing system.
See the FarmShare wiki for examples that run on the barley systems.
