If you’ve been following the launch of Wolfram|Alpha, then you have probably heard that two supercomputer-class systems are a big part of what is behind the scenes. One of them is the R Smarr system, belonging to our good friends at R Systems, which is featured in this video. The other is our custom Dell system, highlighted in the Rack ‘n’ Roll video. (That’s me in the blue shirt and the crazy blond hair.) Between the two of them, we can handle around 1800 queries per second (qps). Many people have asked about how we pulled together all of this infrastructure.

First, some background.

Back in mid-March our development team was intensely focused on building Wolfram|Alpha. As each day went by, the pace of development was accelerating and the further we progressed, the faster Wolfram|Alpha was growing in both content and functionality. On the infrastructure side, we had put in place a prudent plan. We knew the rollout would have an audience of early adopters amongst the professional audiences that our company is very familiar with, and we had planned accordingly for a capacity of 200 queries per second. A few colocations spread throughout the United States should do the job; we were well on track to set them up in plenty of time. And we thought that our “I’m sorry, Dave, I’m afraid I can’t do that” message would be seen occasionally in the first few weeks if there was overflow beyond our capacity. More »
