| FastX is a suite of applications used by many in the engineering community for the analysis of multi-body dynamics problems that aid the medical, automotive, aerospace, defense, and manufacturing communitythe enabling software used to provide web browser based access to the Tufts High Performance Compute (HPC) cluster. It eliminates the need to install software on your local computer such as Xming, Cygwin, or other ssh, X11 style solutions. |

How do I run Abaqus?
There are several ways to run jobs. Most will find the following useful for checking syntax,etc..:
-bash-3.2$ module load abaqus -bash-3.2$ srun ... abq682.exe job=mydesign datacheck interactive input=./design.inp |
|---|
To actually run the code, remove the option datacheck and interactive.
This will run your abaqus input file called design.inp as a serial job and if successful will create about 14 files in the directory you are working in. One such file is the .odb Abaqus database file. All the files are created with the job name "mydesign" and differ in the filename extensions and type of file.
Note, normally there are several versions of Abaqus available. Therefore one needs to note which one reflects what was set up with Modules. For example, the command abq682.exe is version specific.
How do I run a parallel Abaqus job?
| -bash-3.2$ srun ... abq682.exe job=design_4cpus cpus=4 mp_mode=mpi input=./design.inp |
|---|
Note different Abaqus products may invoke different solvers. Check the documentation for options.
How can I find the abaqus command line options?
Suppose you are using the default version of abaqus.
> module load abaqus >srun --pty --x11=first -p interactive abq6112.exe -help This will produce a several page list of command line options. |
|---|
How can find out what abaqus licenses are available?
> module load abaqus > srun --pty --x11=first -p interactive abq6112.exe licensing lmstat -a -c |

How do I run Abaqus version 6.9.2 CAE gui?
| -bash-3.2$ srun ... abq692.exe cae |
|---|
Why is OpenGl not working with CAE?
Add the -mesa option to the start of abaqus as mentioned above.
How do I read Abaqus documentation?
If you have X11 forwarding in place you will get a webpage with documentation.
-bash-3.2$ module load abaqus -bash-3.2$ srun ... abq682.exe doc |
|---|
use it?
Accessing FastX is easy, there is nothing to install, simply point your browser to http://fastx.cluster.tufts.edu/ and login. You will then be connected to the cluster and given an x11 terminal session using gnome-terminal from which batch jobs, interactive jobs can be submitted. If you do not have ssh keys setup it will ask for your password twice.
Does this eliminate the need to install a file transfer program?
No, you will still need to install a file transfer program in order to transfer files between your desktop, laptop and the compute cluster. This functionality may be built into FastX in the future. File transfer applications include WinScp, Cyberduck, Filezilla or scp, sftp, rsync over ssh for those who like to use the command line.
Does FastX require a client application to be installed?
No, since it is web based no client installation is necessary. A client is available however for Mac, Linux and Windows which may give a slight performance advantage for 3D rendering applications. Most users will find this unnecessary. Please contact tts-research@tufts.edu for more information regarding the client, how to download, configure and connect.
