Herrera on Hardware: Is Cloud-Based CAD Ready for Prime Time? Part 2

Centralized, server-side graphical computing technology is on the upswing — but will it stay that way?
 

By Alex Herrera
 

Where should the concentration of power for high-performance computing reside? The first part of this series retraced the basic history of client/server computing, in which the prevailing wisdom at times pushed that concentration toward servers in the datacenter and at others swung it toward desktop workstations. Today, IT strategies are in flux again, with many headed in a very clear direction: toward server-based computing (SBC) models that pack not only computation and data on the server but — for the first time — high-performance graphics processing as well.

Manifested in a range of IT solutions tagged with hot buzzwords — such as virtual desktop infrastructure (VDI), desktops as a service (DaaS), hosted virtual desktops (HVD), and, of course, cloud computing — SBC approaches the promised IT nirvana: anytime, anywhere access enabling across-the-globe collaboration, along with the ultimate in security and ease of management. By keeping models and databases resident in a central resource, IT managers are far better equipped to manage everything in this age of "big data." And most relevant to those relying on visually intensive CAD applications, this latest thrust in SBC is promising one more feature: interactive, high-performance 3D graphics.

Past Obstacles to SBC Viability

Despite an appealing list of advantages over traditional client-side solutions, including workstations, SBC approaches today are virtually nonexistent in CAD and other professional computing spaces — and for good reason. Previous attempts to centralize data, computation, and rendering have failed to deliver the workstation-caliber experience a CAD user demands. Rather, past SBC solutions have required an unworkable compromise: Secure the benefits of centralized computing or enjoy high-performance graphics computing, but not both.

While attractive in theory, it turns out delivering high-performance interactive graphics from a single, centralized computing resource to a remote client is anything but easy. Historically, two fundamental problems have stood in the way: excessive latency and a bandwidth paradigm particularly unsuited to remote visualization.

High-performance computer graphics processing is a notorious bandwidth hog, when it comes to both rendering and displaying the 3D image — and it's that attribute that has made SBC solutions a nonstarter for graphics-intensive computing. With a conventional client-side model, only model data is transmitted from server to client (and that perhaps happens infrequently, as a designer "checks out" a model from a project database). All pixel data stays local on the client. But in an SBC model, in contrast, the server performs rendering and transmits only the resulting pixel images to the client. Model data never leaves the server. Read more »
