Correct "nice" POSIX scheduling priority for batch processing program

fixed the issue. Will look into that further If it's good enough for Scott Guthrie, then I'd consider it the correct way to do it (for now, they could always fix this in VS 2010!).

should help you out Unfortunately most GPU's do not support running several tasks at a time, and so there is no way to assign priority. This means that when your OpenCL kernel is running, it is the only task being executed by the GPU and that will be the case until the kernel is complete.
If you want the computer to be usable while running the kernel (normal desktop activity, browsing, videos, games) each kernel iteration would have to be very quick. So if you can reduce the time taken by each set of kernel launches (i.e. each job enqueued with clEnqueueNDRangeKernel) you might get what you're looking for. This could be achieved either through making the NDRange smaller, though it needs to be big enough to be efficient on the GPU. Something like 5120 work-items is what I've found to be the minimum on Radeon HD 5870. Or you could reduce the amount of work in each kernel.

like below fixes the issue It means processes that have been started with the nice command, or have called nice/setpriority to lower their priority below the standard one. (nice was the name of the system call in older unixes as well, it's been replaced by setpriority now. The command name is still the same).
See the manual page or documentation for /proc/stat, for example, http://www.mjmwired.net/kernel/Documentation/filesystems/proc.txt.

hop of those help? Actually...Niceness is a property of the application according to POSIX.1. Here is a more detailed post. is nice() used to change the thread priority or the process priority?

may help you . Install Java 8 JDK (not JRE) on your development machine as it is a prerequisite for running the Kotlin compiler, and also for any Java or Kotlin application. You can use either the Oracle JDK for most platforms or OpenJDK for Linux platforms.
