Standalone

The Dynamo standalone is the version of Dynamo that runs without any Matlab installation. A standalone package carries its own "Matlab" version in the form of MCR libraries.

Activating the standalone

To use Dynamo is standalone modus in a shell, you need to activate first that shell, typically with:

source <DYNAMO_ROOT>/dynamo_activate_linux_shippedMRC.sh

Using the standalone

Our advice to work with the Dynamo standalone is to use at least two linux shells. You would use one shell (let's call it console shell) to run an interactive Dynamo console, where you can create projects, view tomograms or analyse results. In a second linux shell (let's call it computing shell), you can launch the projects edited on the first shell.

Dynamomust be active in both shells!

On the Console shell

• Using the Wizard GUI

  Make certain that when you create a project, you use the standalone option in the Computing environment GUI. Each "core" will be handled by a different openMP process. You can also run alignment projects in the GPU, in which case you also have to mark the set of GPU identifiers.

• Using the command line

  In case that you are designing your project from the command line, the parameter that controls the environment is called destination. To use the standalone, it should be tuned to system_omp for multicore projects, or to system_gpu for GPU projects.

In both cases you can check and unfold the project in the GUI handled by the Dynamo console to produce an execution script. A project called myProject will generate an standalone script called myProject.exe. Instead of running the project in the Console shell, the Console will be blocked until the project is finished (and wont show any results on screen).

On the computation shell

To execute a project myProject in a shell, you don't need to open any Dynamo console first. Just type:

myProject.exe

or

./myProject.exe

depending on your system configuration. You might also need to adjust permissions through:

{{{1}}}

Advantages over the Matlab version

Besides the obvious advantage of not requiring the purchase of any Matlab license, there are some minor functionalities in Dynamo that would require an extra Toolbox on top of the basic Matlab license, as Statistics or Curve fitting. These functionalities are never used in the basic pipeline of Dynamo, but are part of the extended tools offered by Dynamo through its command line. When you use the standalone, all mathematical toolboxes are automatically available.

Additionally, the standalone version is automatically delivered with the newest Matlab version. If you are running Dynamo on Matlab versions previous to release R2014b, you can experiment visualization problems in some programs.

Functionality restrictions

There is one single functionality not available in the standalone version: although multicore projects can be run normally, the averaging step of each iteration will run on single core. For most projects, this limitation has no practical effect, as the numerical bottleneck is the alignment step.
