BANGALORE, INDIA: Parallelism or parallel computing involves the simultaneous use of more than one computer or processor to execute a program. Ideally, parallel processing makes a program run faster as there are more engines (CPUs) running it. Even single-core processor computers can perform parallel processing by connecting to other computers in a network.

India has been slow off the blocks as far as parallelism is concerned. Intel is undertaking various programs to ensure that software developers in Inda keep pace with the latest developments.

James Reinders, Chief Software Evangelist and Director of Intel Software Development Products, said that Intel has been developing microprocessors for a long time. "You can double performance and reduce power. Power consumption in a microprocessor isn't something that the industry wants. The solution is to add cores," he added. 

There are bandwidth challenges with multicore. Intel will be adding QuickPath technology later this year. Providing point-to-point high-speed links to distributed shared memory, the Intel QuickPath technology unleashes the parallel processing performance of next-generation Intel 45nm microarchitectures (codenamed Nehalem and Tukwila).

These microarchitectures, built from the ground up, will be the first to use the Intel QuickPath interconnect system and can see significant improvements in overall performance.

Reinders added, "We will also go to eight cores this year. We are looking at working with developers, so that they can take advantage of the cores. We need to look at how they can make parallel programming more flexible."

Tech challenges
Intel has been seeing pretty strong trends of users using parallelism or perhaps, trying to figure out how to use it best.

The most active areas where parallelism is currently being used are in scientific applications and high-performance computing. The challenge is in the high-performance computing area, which involves lot of digital media content, said Reinders.

Indian scenario
Commenting on the scenario in India, Narendra Bhandari, Director, Intel Software and Solutions Group, said: "In India, we have been interacting with the telecom software companies. They have gone on to build parallelism, and actually delivered to local customers."

Reinders further added: "In Karnataka, we have interacted with an educational software company. We have tools that analyze what their programs do. Very quickly, they agree to discuss, and three to five weeks later, they are able to release new patches of their products."

Citing Tally as an example, Bhandari said: "We were able help Tally look at their applications. As the data load increases, challenges increase as well. They have since seen dramatic improvements in their applications. Yet another example is an animation company. We looked at their rendering. In two months or less, they saw the results. We showed them where the paradigm was shifting."
 
According to Intel, the interest levels in the adoption of the tools, as per the downloads and sales, etc., has gone up from 3x to 5x. "Traffic is quite high on our software network portal. This is the traffic to the geeky portion of Intel. All of these trends indicate that the awareness regarding parallelism has been very good in India," added Reinders.
