问题 We use SQLite library in our product and suddenly after recompilation with different compiler version (Visual C++) it started crashing on customer computers. The crash is ExceptionAddress: 0710eadd (sqlite3!sqlite3_transfer_bindings+0x0004e5bd) ExceptionCode: c0000005 (Access violation) ExceptionFlags: 00000000 NumberParameters: 2 Parameter[0]: 00000001 Parameter[1]: 07148688 Attempt to write to address 07148688 and the code causing the crash is the following (part of sqlite3MutexInit):

Differences between cl_khr_fp64 and cl_amd_fp64?

微笑、不失礼 提交于 2019-12-22 00:02:47
问题 I just found that on my (pretty expensive) Radeon 6970, only cl_amd_fp64 extension is supported. I am getting odd results in some parts of the code (accessing the value of 0.005 actually uses 1.99916e+37 ?) when running with cl_amd_fp64 . Using cl_khr_fp64 with Intel SDK on the CPU works just fine. (The input buffers are exactly the same) The extension page gives very little information. What are exactly the differences between both? 回答1: cl_khr_fp64 is the Khronos official double precision

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 3 years ago . I'm attempting to configure the new Android Virtual Machine Acceleration. I'm following the steps outlined here. I get to the point where I need to execute: <sdk>/extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM.exe. When I try and run the installer for this, it fails and says " VT not present: Your

How much should I worry about the Intel C++ compiler emitting suboptimal code for AMD?

心不动则不痛 提交于 2019-12-18 13:55:07
问题 We've always been an Intel shop. All the developers use Intel machines, recommended platform for end users is Intel, and if end users want to run on AMD it's their lookout. Maybe the test department had an AMD machine somewhere to check we didn't ship anything completely broken, but that was about it. Up until a few of years ago we just used the MSVC compiler and since it doesn't really offer a lot of processor tuning options beyond SSE level, noone worried too much about whether the code

Android Studio emulator and AMD CPU

问题 I can't run my app on standard Nexus 5 emulator. It seems it requires Intel HAXM but i have an AMD processor. So how can i use the emulator without buying an Intel processor (or installing Linux)? 回答1: If you have an AMD processor, you can download an ARM image, but it is super slow on x86 platforms. The x86 image does not work with AMD CPUs, because the x86 image needs HAXM installed which needs VT-X support, and only Intel CPUs support it. So you can download the Genymotion emulator, which

Run Android studio emulator on AMD processor

问题 Android newbie. My processor is AMD, not Intel, so I can't open the emulator in Android studio. This answer has the comment: 'You can run the ARM (non Intel) emulator image. From your list, just choose a non Intel emulation.' They don't explain where this can be found. Any ideas? Thanks Android Studio emulator and AMD CPU 回答1: Alright, first of all, open your Android SDK Manager: Tools -> Android -> SDK Manager, then chose any platform/package you want to download, expand it and select ARM

OpenCl: Minimal configuration to work with AMD GPU

 ̄綄美尐妖づ 提交于 2019-12-13 06:12:41
问题 Suppose we have AMD GPU (for example Radeon HD 7970) and minimal linux system without X and etc. What should be installed and what should be launched and how it should be launched to have proper OpenCL environment? In best case it should be headless environment. Requirements to environment: GPU visible by OpenCL programs ( clinfo for example) It is possible to monitor temperature and set fan speed (for example using aticonfig ). P.S. Simple install Xserver, catalyst and run X :0 won't work

Why is my java application faster on an AMD processor?

佐手、 提交于 2019-12-12 23:14:23
问题 I made the observation that my java application is running much faster when executed on an AMD processor in contrast to an Intel CPU. For example my JBoss starts in about 30 seconds on a 3 GHz AMD processor and needs about 60 seconds on a 3 GHz Intel processor with identical disc, RAM and OS? Has anyone else made this observation? Why is this so? 回答1: It depends on the CPU generation as well - clock speed is not everything. If you set up e.g. an Intel Pentium 4 and an AMD Phenom with the same
