micro-op is written in advance, my question is how this one-to-one ing relationship is implemented, because I have not seen the qemu-0.9 version beforeCode So I want to know how Hand coded. In addition, this article also mentions "When qemu first encountersA piece of target code, it translates it to host code ....... ", my question is, how does qemu process objective files on the target platform? For example, how does qemu analyze an elf file, how does it read instructions from it, and how does
Yahoo! Researchers used hadoop to complete the Jim Gray benchmark sorting, which contains many related benchmarks, each of which has its own rules. All sorting benchmarks are determined by measuring the sorting time of different records. Each record is 100 bytes. The first 10 bytes are keys, and the rest are numerical values. Minutesort compares the data size sorted within one minute, and graysort compares the sorting rate (TBS/minute) when sorting la

A friend and I talked to a case, a tablespace originally had a data file (already has a lot of data entered), then he added 7 data files, this time he found that he added more files, want to delete these data files, but do not understand the database, directly offline the table space, and then rm the relevant data files, The last table space cannot be online. I have simulated the recovery test for the scene, restoring it using bbed and Dul
