Hydra update pushes single-threaded applications out to parallel grids

November 7, 2008 —  More heads mean more brains. And while humans are relatively adept at splitting up work among extra heads, creating software parallelism isn't always that easy. Rogue Wave is hoping to solve that problem with Hydra, its new service grid released yesterday.

This bundle of tools, which includes a server-side runtime environment, can take existing single-threaded applications and make them process in parallel across a grid.

Patrick Leonard, vice president of engineering and product strategy at Rogue Wave, said that Hydra works with C++, Java and BPEL code. Additional plug-ins are available for COBOL and Fortran, though implementing both of these requires the application of a thin layer of C++ around the legacy code.

“We're combining the concepts of service-oriented architecture and high-performance computing, which traditionally don't live in the same domain,” said Leonard. “The hard part about making business applications parallel is that business applications don't often lend themselves to being parallel. They have dependencies and workflows and things like that that make it hard to do parallel applications.

“Traditionally, if you're writing in Java, you might use the concurrency package. If you're writing in C++, you might use threads or OpenMP. [Hydra] is complementary to that. Think of it as the next level higher in the stack. You get the service to execute in our runtime. Then the runtime allows you to configure how many you want, how many can run at the same time and what messages go where."

Hydra includes a command-line interface and an Eclipse-based configuration tool. “You can do pretty much anything you want to do from [the] command line," said Leonard. "We provide a host of IDE tools and plug-ins to Eclipse for development. These support the creation of WSDL; we can generate services from WSDLs. Then we provide tools for deployment and configuration management."
