Guides for BlueCrystal users

Please also refer to the Support page for links to BlueCrystal user guides and details of how to request help with a specific problem.

Reference guides

BlueCrystal quick reference guide

This quick reference guide for both new and experienced users gives a summary of useful commands when using BlueCrystal.

Topics include:

Configuring your environment
Using the queueing system
Useful commands

Emacs reference card

Emacs is a text editor that offers more support to programmers, through its various modes, than more generic editors, such as gedit or nano. Emacs uses a large number of key combinations as time-saving short cuts. The guide is a handy quick reference to the most commonly used key combinations.

Topics include:

Files
Formatting
Regular expressions

ACRC 'How-To' guides

We have developed some short 'How-To' guides. Let us know if there are other topics you would like to see in this series.

Getting Started with Compiler Flags Introduces compiler flags which can help to optimize our programs for speed Analyse the performance of our programs Find bugs.	Using Accelerators - GPUs and Co-processors - on BlueCrystal Phase 3 An overview of the physical make-up of accelerators Their computational strengths and weaknesses How you can practically make use of them
Customising Environment Variables Setting variables to help you run programs and applications. Setting variables in your shell start-up files--such as your .bashrc file--so that customisations are in place automatically, whenever you login. Using environment modules, such as those available on bluecrystal, to achieve customisations in a more convenient manner.	Linking to Libraries A short explanation of the difference between static and dynamic linking Examples of using the GNU C and Fortran compilers to link to the LAPACK library of routines for linear algebra A description of how the 'reference' LAPACK, OpenBLAS and SLATEC libraries can be built from source code.
Recipes for Using Allinea's DDT Parallel Debugger on BlueCrystal Phase 3 Building your Program. Using DDT to Submit a Job to the Queuing System. Attaching DDT to a Job Already Running.	Running MATLAB on BlueCrystal Available toolboxes. Packaging your code using the MATLAB compiler. High performance MATLAB. Link to MathWorks tutorials on Matlab and Simulink
Submitting job arrays to BlueCrystal Phase 3 Submitting all your jobs with a single command. Modifying (or deleting) all, or a range of your jobs, again with a single command. An example submission script.	Using Intel VTune Amplifier on BlueCrystal Phase 3 Preparing your application Performing a Hotspot Analysis in Batch Mode Profiling Multi-threaded Code and MPI code
Running large memory jobs on BlueCrystal Phase 3 Running large memory jobs on standard nodes. Running large memory jobs on high memory nodes. Running large memory jobs on a vSMP node.
