问题 I run a raytracer in CUDA with N Bounces (each ray will bounce N times). I view the results using openGL. once N is small (1~4) everything works great. once i make N big (~10) each thread (about 800x1000) has to do a lot of computing and this when the screen goes black, and than back on, with the note that my nvidia crash. i searched online and think now that what cause it some sort of a watch-dog timer since i use the same graphic card for my display and my computing (computing takes more

问题 Is it possible to execute shell command in kernel module. I know that we can do it in user space C code using system subroutine. I am debugging a kernel module which has memory leak issue. After doing insmod and rmmod module.ko in an infinite loop, system goes out of memory within few minutes with 8G RAM. It would be helpful to know memory status using free command before and after the call to API responsible to free memory so i can know that API is working or not. This is the way i am

问题 I cannot make DbgView.exe work properly on my Windows 10 64-bit v2004 Virtual Machine. The program doesn't capture any kernel message from the driver if using KdPrint, but works fine with DbgPrint. I've already tried "bcdedit /debug on", adding "Debug Print Filter" on the registry editor and rebooting, enabling verbose kernel output. I've also tried on my host machine, same outcome. It is a very simple driver, only to be loaded and unloaded, copied from the book Windows Kernel Programming.

The response header is Content-Disposition: attachment; filename=sample.txt But I don't know how to do it. Is that possible? 回答1: Sorry we haven't implemented it yet. If you have some sample Selenium code we can take a look at that. Maybe we should open a feature request. 来源： https://stackoverflow.com/questions/56329658/can-upload-download-files-at

问题 I would like to know what precisely is happening since php script runs the query to the moment when database returns data and php script starts to fetch them. In theory, I have a Postgre database with huge table, talking about 10/20 million records with 20+ columns and I have a php script which is requesting all that rows from database to be placed in, lets say, some file.
