Why use RVEC?

Fujitsu’s Gateway Remote Visualisation is a system to manage sessions on remote graphical servers and establish direct client connection from within the HPC Gateway web desktop. Image transmission between the server and client device is done with Fujitsu’s own Remote Virtual Environment Computing (RVEC) technology for intelligent and lossless data compression. RVEC is particular adapted for applications that demand the most precise replication such as 3D graphically-intensive CAD and CAE pre/post-processing tools.

RVEC Architecture

RVEC comprises Client and Server software-only components that communicate to transmit a compressed display from a remote system to a user device. The Server intercepts graphical frames and compresses the information for transmission to the Client for decompression and display.

RVEC uses a differential process that converts a region within the screen having many updates to video while sending all other differences in screen updates as still images. Transfer of these two types of regions to the client terminal is done using the system appropriate for each (RVEC original protocol). It measures the number of screen updates for each fixed time period corresponding to the drawing frame rate and is constantly adjusting the video and still-image regions to optimally control the amount of transferred data to match the relative activity on the screen. Dedicated hardware is avoided by concentrating the video region in one portion of the desktop screen to improve processing efficiency.

RVEC connection brokering

Activation and use of a RVEC Server is managed within Fujitsu’s HPC Gateway. Its Remote Visualisation Manager dynamically shows all available RVEC servers and their status. Gateway’s internal access control security restricts usage only to RVEC servers permitted for the connected identity.

Application and system consolidation

Through its advanced data compression capability and lossless precision, RVEC enables users of even the most sophisticated and fine-detailed 3D applications to work remotely.  CAD1 and CAE1 applications can be extremely demanding to use in this way since the models contain a very large amount of information, and where specific placement of features within the model is critical.
