processor

问题 I am designing a work which takes a data from on database in MySQl to another database(MySQL) using ExecuteSQL processor followed up with ConvertAvroToJson then ConvertJsonToSQL then PutSQL as shown in below flow chart ConvertJSONToSQL returning the empty values like below INSERT INTO source_count (field1, field2, field3, field4, field5, field6, field7, field8, field9, field10, field11, field12) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) The processor configuration is what can be wrong in

问题 Is there a Windows API or any way to determine on which physical processor/core my current thread runs? I don't need that information. I'm just curious. I'm not interested in the processors the thread is allowed to run on. I would like to know on exactly which one it currently runs. I know that the threads switch pretty fast from one to another... 回答1: Threads will often switch from processor to processor, so it's kind of meaningless, but you can use GetCurrentProcessorNumber. As others have

问题 My app needs Renderscript since it performs some image processing that would take several seconds in Java. Before publishing I have tested it on a number of devices, even some older models (e.g. Samsung Galaxy Tab 2, API 17), and the app worked quite well, even on these devices. From this, I didn't see a reason to set the minimum API higher than 17. Now, some weeks after publishing on Google Play I see that the app crashes on certain devices such as Galaxy S3 (m0) with API 17 or Galaxy S3

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . Are there any still-relevant CPUs (Intel/AMD/Atom) which don't support SSSE3 instructions? What's the most recent CPU without SSSE3? 回答1: The most recent CPUs without SSSE3 are based on the AMD K10 microarchitecture: AMD Phenom II , the last-generation K10 socketed desktop CPUs before Bulldozer-family. They were

问题 Is there a way to find out which processor (either on a single system or mutliple systems) your thread is running on, using Java native threads? If not, is there any library which could help? 回答1: The JVM's thread scheduler is JVM-specific, so there is no 'universal' solution. As far as I know there is nothing available out-of-the-box, but perhaps using: the Sun JVM; Solaris - or Mac, as Tom Hawtin - tackline points out; DTrace. you might have some luck: trace a thread-start probe, which has

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Performance of built-in types : char vs short vs int vs. float vs. double Hi. Assume, that you have 32-bit processor. Are 8-bit char and 16-bit short int types slower than native 32-bit int ? What about using 64-bit long long int ? Are this datatypes supported by hardware by default, or they are all transformed into 32-bit data anyway, by using additional instructions? In case, that I have to store a small

问题 Having looked for a description of the multicore design i keep finding several diagrams, but all of them look somewhat like this: I know from looking at i7z command output that different cores can run at different frequencies. This would suggest that the decisions regarding which core will be given a new process and for changing the frequency of the core itself are done either by the operating system or by the control block of the core itself. My question is: What controls the frequencies of

问题 We are catching errors in our CMake makefiles due to lack of -fPIC . Her's one from a ci20 MIPS dev-board: ...

问题 I've googled these topics, but not sure if I understood their relations correctly. I summed up the following points, please correct/complement. 32-bit or 64-bit processor means the processor can process 32/64 bits at once. Using 32-bit or 64-bit processor indicates the underlying registers, address buses, or data buses are also of the same size. In order to work on 32/64-bit processor, we have 32/64-bit OS In order to work in 32/64-bit OS, we develop 32/64-bit application It is possible to

On this website, as my reference the author states that the immediate will be sign extened Description: Adds a register and a sign-extended immediate value and stores the result in a register Operation: $t = $s + imm; advance_pc (4); Syntax: addiu $t, $s, imm Encoding: 0010 01ss ssst tttt iiii iiii iiii iiii If I have the following instructions lui $3,0x1001 addiu $3,$3,0x8010 and I
