LabVIEW prohibits other multi-core processing applications from executing on all cores

LabVIEW Prohibit other multi-core applications from executing on all cores

After installation LabVIEW after , Some applications can only execute on one core , And before installation , Applications can run on multiple cores . Open or not LabVIEW The same will happen . What's the situation , And how to solve ？

answer ： In the installation LabVIEW When , The installation file will set a Windows environment variable （environment variable）, called MKL_SERIAL, Set it to YES . This is a Intel Math Kernel Library Set up , Will make this library In sequence （serial） By . LabVIEW There are multiple threads in itself （multithreading） The function of , And make sure that MKL_SERIAL Set to YES To send threads to this library in .

This makes LabVIEW It can more skillfully generate threads suitable for the program . Intel In this library Provides some multithreaded processing , But in many cases, you need to turn off this function , therefore Intel They suggest that applications or compilers handle multithreading on their own . If other applications cannot handle their own threads , take MKL_SERIAL The value of is set to YES Will limit them , It becomes that it can only be executed on a single core environment . The reason is that these applications rely on library To handle their own threads .

If you can run LabVIEW when MKL_SERIAL The value is set to NO, You may encounter memory errors and LabVIEW The ability to control threads is weakened , Therefore, it is not recommended to perform... Under such a setting LabVIEW . If you really have to change the value of this environment variable , Please make sure you are running LabVIEW Change it back to YES ..
