With the increasing number of cores in multicore processors, it is challenging task how to take advantage of powerful parallel computing for the deep packet inspection. This paper introduces the deep packet inspection with a parallel method which exploits the message-passing interface (MPI). The parallel procedure includes the master thread and the slave thread. The master assigns the data packet to the slave. The slave executes the string matching with rules for inspecting. Both the master and the slave communicate by using MPI functions. The experimental results show that the parallel method is suitable for the trend of the increasing number of cores in multicore processors. Moreover, when the number of threads is equal to the number of cores in multicore processors, the performance arrives at the maximum throughput.

Obesity is one of the leading health risk factors worldwide and is associated with several other risk factors and health problems. Acupuncture is utilized to treat a variety of health problems, one of which is obesity. Fifty-six obese women with body mass index (BMI) ≥25 kg/m2 were recruited for this trial and were randomly divided into two groups, one with combined manual acupuncture and massage therapy (MAMT), and the other with only manual acupuncture therapy (MAT). In addition, 40 overweight women with BMI 23–25 kg/m2 were randomly divided into two groups, one with MAMT and the other with MAT. Therapy was carried out once per day for 21 days, and the body weights and the BMIs were recorded every day. The results showed that both MAMT and MAT could reduce body weight and BMI significantly, compared with the pretreatment values, for all the participants (p < 0.001); however, the differences in body weight and BMI reductions between pre- and posttreatment for the MAMT and the MAT groups were not statistically significant. The optimal periods for reductions in both body weight and in BMI were the first 4 days. Accounting for the economic strategy (time and money) in alternative therapy, MAT alone may present a reasonable option in the treatment of overweight and obesity in adults.
