594470 V. Description of the invention (1) [Technical Field of the Invention] The present invention is a file system using multiple threads and multiple files, and α method ', especially method. Tiananmeng conducts pressure measurement. [Prior technology] The file system is a computer operating system. It requires computer storage equipment and chapters. When the pressure is greater! = Coordination and coordination, the more likely it is that the case-building system will appear in time: 疋 The operation is very important, so the analogy with the actual operation; The stress test becomes very important. The purpose of the stress test of the Caitian Case 糸 file system is to put pressure on the logical drive case. The operating objects include hard disk drives (Removeable Storage) and actuators. (CDROM), floppy disk drive (n0ppy Disk) and network drive (Network Device), etc., file operations include reading, writing, copying, creating and deleting. The test of the blessing case system is generally performed on a single slot case through different eaves case operation paths and different file creation methods. The storage of the file is to continue to store in the nearest blank cluster after opening the blank cluster found first. When the file is deleted, the original cluster is released. The first cluster released will be the next storage file and a medicine. Restoring the file will also overwrite the previously released puppet. The operation of a single file can only be performed in a fixed storage area. The normal operation of a busy machine is especially to increase the volume of the disc drive and move the operation. The analogy starts, but the first obvious use of the case , get on,

Page 6 594470 V. Description of the invention (3) The test result and the running time are executed in the file operation of the test thread; the test thread is ended. Compared with traditional detection methods, the method provided by the present invention uses multiple threads and multiple files operations to increase the stress and coverage area of the file system test, reasonably schedule each thread through a specific algorithm, and monitor the remaining storage space of the logical drive. Thereby a better analogy of file operations in the real environment. When performing a test on an optical disc drive, open the file on the optical disc to read the entire disc by using a shared method. When performing a test on a floppy disc drive, each thread writes only one file as small as possible to reduce the response time. Therefore, the test for the optical disk and the floppy disk drive can support more threads, realize a real multi-thread, and improve the test efficiency and pressure.

Description of the invention (7) P r occessing U nit CPU time will reach 100%, other test items will not run normally In order to solve this problem, the present invention introduces a test interval (T est Interva 1) parameter in the stress test of the file system, so that the file system hangs for a period of time after each file operation, giving CPU time to other test items. When the file system is ready, it will get the priority response from the CPU again. In this way, not only will the test pressure on the system storage equipment be significantly increased, but it will not cause images to test other test items, thereby improving the efficiency of system testing.

During the stress test of the file system, due to the needs of the test, some temporary storage slots will be generated on the current logical drive for testing. If the test program exits abnormally during the test, cleaning these temporary files will It is very tedious, and if it is not completely cleaned up, it will occupy the storage space of the drive. Therefore, in order to solve this problem, the present invention creates a temporary directory for each test thread, and stores these temporary files in the directory. , After the test is completed, the temporary file cleaning becomes simpler, just delete the temporary directory. Please refer to "Figure 3", which is a flowchart of the file operation in the execution of the test thread according to the test result and the runtime according to the present invention, as described below:

After step 140, when the logical drive has no remaining storage space, end the test thread step (3 1 0); when the logical drive has remaining storage space and the test execution time is within the running time, then Continue to execute the file operation in the test thread (step 3 2 0); when the logical drive has remaining storage space, but the test execution time exceeds the running time
