HyperThreading

What we generally encounter for database as opposed to purely computational work is that without Intel’s HyperThreading (blue bars on the chart above) wall clock time for a quad core processor minimizes at about 10 threads. With HyperThreading (red bars on the chart on the previous page) the minimum is 15% to 20% lower (here about a significant 60 seconds) and there are gains to be realized from scheduling 6 to 8 additional threads.

ThreadAverageSpeeds

As the number of threads increases it is reasonable to expect a slight linear increase in the time needed to process a fixed number of transactions.

It seemed to us that with a reasonable CPU, a decent hard disk and some aggressive thread management, we could sort out the incoming devices and capture the sensor measurements. Then Professor Peter Wayne and others at Harvard Medical school e-wrote to tell us it was important to measure even during sitting and standing. The ideal in the WuJi style of meditation we teach is to be motionless. What they had found was that sway – how far and how quickly one’s head moved from an ideal position – was a powerful indicator.

So now we had much less time to do a great deal more work.

Most aides carry devices like an iPad and some students also have smart phones. The SAITO software has to sort out what a device does and who it belongs to. Class starts with a formal bow and salute, followed by five minutes of sitting meditation and then five minutes of standing meditation. Then several minutes of centuries-old Chen family warm-up exercises, so we had thought we had a comfortable amount of time until the first Tai Chi Chuan set to perform this identification process. Until Professor Peter Wayne and others at Harvard Medical School pointed out it was useful to measure movements during sitting and standing. We’ll see what the upcoming Internet of Things Conference and the Sensors Expo (both in San Jose California in May and June, respectively) showcase in terms of hardware, but we are leaning toward pressure sensors embedded in chair seats and personal foot mats.

The shortest and simplest (and, therefore, the first taught) of the Chen Family style sets is known by the precise but not especially imaginative name of 18 Movements. Once they learn this set, students would perform it twice per class forever. The students can see a canonical video of Grandmaster Chen Zhenglei, who choreographed 18 Movements, either projected on large mirrors or on smart glasses. 16 students times 20 sensors ties several times per second gets to be a lot of measurements to store in a database very quickly. Well over 100,000 sustained database inserts per minute. And we have to extract the raw sensor data from the Internet of Things hub where it is stored.
