Abstract: An active scheduling method performed with a master processor and a plurality of slave processors. The method includes determining whether a job to be performed has a dependency by referencing a job queue; in a case in which it is determined that the job to be performed has a dependency, updating a state of the job to be performed in a table in which information of each of a plurality of jobs is recorded; analyzing a state of a job preceding the job to be performed based on the table; and in a case in which the job preceding the job to be performed is determined to have been completed, performing the job to be performed by retrieving the job to be performed from the job queue.

Abstract: A wafer measurement apparatus includes an electronic-optical system configured to irradiate a wafer with an electron beam and acquire a raw signal by detecting electrons emitted by the wafer, and an image processing device configured to convert the raw signal acquired by the electronic-optical system into image data. The electronic-optical system includes a detector configured to acquire the raw signal. The detector calibrates a gain offset using a difference in electron emission yields of different materials.

Abstract: A method of operating the accelerator includes receiving a request for preemption during an execution of a first task using one or more processing elements included in the accelerator, in response to the request for preemption, moving context information of the first task stored in an internal memory of the accelerator to an external memory of the accelerator, and executing a second task associated with the request for preemption using the processing elements.
