“…A significant amount of recent research is devoted solely to collecting unbiased edge, path, and call stack profiles [31,37,46,47], and one such paper even won the best paper award at PLDI 2009 [2]. This ostensibly simple feature should have long ago become a commodity, programmable and accessible from user space.…”

“…This research in this clouds work of system development on with the entire facial suture; the system function provided the parameters setting, the question bank design, and online questionnaire design and material inquiry, to draw lots to draw, and made the synthesis implementation to appraise to its subject matter [10,15], such as Figure 4 establishing the questionnaire time needed comparison chart, according to the statistical result before the edition correction; it uses the system to establish 262 effective questionnaires to take the time-consuming 25747.96 seconds to be equal to 419.23 minutes is 7.15 hours, but it improves the flow to promote the system function to complement one another under the edition correction; it uses system to establish 262 effective questionnaires only to need time-consuming 1784.56 seconds to be equal to 29.74 minutes is 0.49 hour, the significance reduced for 6.66 hours. The operating time, simultaneously working efficiency significance, is promoted 16.98 times.…”

The teaching evaluation questionnaire in the university has been an essential routine. The administrative staff of academic affairs shall obey the rules, fairness, and valid principles within the period of finishing teaching evaluation questionnaire. To ensure the accuracy and timeliness of the large number of questionnaires, it makes the administrative staff of academic affairs face the challenge and pressure if the students are too many. Program potency low or bad often came from the development staff being familiar with bad program development idea; the bad designs of system program in itself causes the factor proportion to occupy more higher, because the similar application program mode of writing is, respectively, different. However, the exploiter may find the method of the little consumption of system resources to complete the similar work task. We develop the software service of cloud platform and the educational administration personnel operates process in the software service of cloud platform. The cloud platform reduces the system wait and calculation time of questionnaire, improves and simplifies system operation flow, and promotes 10 times of program efficiencies as well as solving the load overweight problem of potency bottleneck.

“…Processor hardware features for profiling [5,26,27,43] cannot completely eliminate software overhead; even hardware-accelerated profiling must somehow record profiling information, which necessarily affects the programs being profiled. In particular, external hardware tracers and debuggers [33] can profile without software overhead but require significant processor hardware support to collect and transmit traces off-chip.…”

This paper presents an approach for zero-overhead profiling (ZOP). ZOP accomplishes accurate program profiling with no modification to the program or system during profiling and no dedicated hardware features. To do so, ZOP records the electromagnetic (EM) emanations generated by computing systems during program execution and analyzes the recorded emanations to track a program's execution path and generate profiling information. Our approach consists of two main phases. In the training phase, ZOP instruments the program and runs it against a set of inputs to collect path timing information while simultaneously collecting waveforms for the EM emanations generated by the program. In the profiling phase, ZOP runs the original (i.e., uninstrumented and unmodified) program against inputs whose executions need to be profiled, records the waveforms produced by the program, and matches these waveforms with those collected during training to predict which parts of the code were exercised by the inputs and how often. We evaluated an implementation of ZOP on several benchmarks and our results show that ZOP can predict path profiling information for these benchmarks with greater than 94% accuracy on average.
