Should be appreciated that the above generality of the present invention is described and the following detailed description is all exemplary and explanat, and be intended to the further explanation that the invention provides for as claimed in claim.
Description of drawings
Accompanying drawing is mainly be used to providing, the present invention further to be understood.Accompanying drawing shows embodiments of the invention, and plays the effect of explaining the principle of the invention together with this instructions.In accompanying drawing:
Fig. 1 schematically shows according to the accelerated method based on open computational language of the present invention.
Embodiment
Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 schematically shows according to the accelerated method based on open computational language of the present invention.In the embodiment shown in fig. 1, the accelerated method 100 based on open computational language of the present invention comprises:
Step 101: determine that application program accessed a plurality of available devices of a cloud computing platform;
Step 102: the attribute of the described a plurality of available devices of described cloud computing platform inquiry;
Step 103: described application program compares the attribute of described a plurality of available devices and the requirement of application; And
Step 104: based on the result of described contrast, described application program is selected one of described a plurality of available devices.
Preferably, after described application program is selected one of described a plurality of available devices, described accelerated method further comprises: described application program is invoked at the brief introduction of the upper establishment of one of these a plurality of available devices document via one, and wherein said document brief introduction is used for doing further mutual with one of these a plurality of available devices.
In addition, preferably, the step of the attribute of the described a plurality of available devices of described cloud computing platform inquiry further comprises: described cloud computing platform calls in response to one at least one virtual unit is added one or more as in described a plurality of available devices.According to a preferred embodiment of the present invention, in above-mentioned accelerated method, described virtual unit represents the available resources in described cloud computing platform, and the hardware characteristics of the attribute description corresponding system of described virtual unit.
