#PORTABLE APPS JAVA SOFTWARE#Since the software is pre-installed on the drive, it can also be preconfigured with the necessary preferences required to immediately connect to the resource. The current thumb drive includes all the typical software necessary to connect to an HPC resource, such as X11, ssh, and scp. To access the software from a Windows-based machine, the user simply connects the thumb drive and runs the desired programs. The thumb drive contains all the software necessary to connect to traditional cyber-infrastructure and all programs run directly from the thumb drive - no installation or setup is required. We have developed an alternative solution: a "plug and play" HPC system portal stored on a USB thumb drive. However, not all research projects or High Performance Computing (HPC) centers have the resources necessary to provide scientific gateways. Scientific gateways (such as the TeraGrid Portal ) are one possible solution to this problem. Installing, configuring and running this software is generally a multi-step process that can be overly confusing to novice users and presents a barrier to entry, particularly in research domains not traditionally associated with advanced computation. Even when applications provide a Graphical User Interface (GUI), special software (such as an X11 server) may be required to use the interface. #PORTABLE APPS JAVA INSTALL#For instance, the user may need to install multiple software tools just to connect with advanced hardware, and successfully installing and navigating this software frequently requires the use of Command Line Interfaces (CLI) that are unfamiliar to novice users. However, novice users of cyber-infrastructure are often overwhelmed by the complexities of using cyber-infrastructure. An increasing number of turnkey, domain specific software packages are available to help users take advantage of advanced cyber-infrastructure and resources such as TeraGrid.
