You're right that I could issue a renice command. The problem is that there are 1000s of processes started during the batch. All of these process should have a higher priority than all of the user processes with a nice value of 20.
It seems to me that it would complicate things tremendously if I had to run a separate script after every process to determine the previous process' PID and then to renice it. I also think that this would be detrimental to the overall performance of the whole batch.
I also need a way to allow a non-superuser to renice a negative value. And can anyone tell me a way to determine a process nice value without using Top or Glance?

But donno how to do when its already running..
Any help would be apreciated..

Hi folks,
Hope you can help me. I have a process that is currently running at nice 20 and need it to run faster (-10?). How do I change the process using nice? I have the process number and thought it would be along the lines of;
nice -10 process_id
but it doesn't seem to like that. (1 Reply)

Function Documentation
NSUInteger MPSStateBatchIncrementReadCount (MPSStateBatch *__nullable batch, NSInteger amount)
raise or lower the readcount of a batch by a set amount In some circumstances, a MPSState may appear in a MPSStateBatch multiple times.
This is particularly common when the MPSState serves as an accumulator across the entire batch, such as when accumulating gradients for
convolution weight update or batch statistics for batch normalization. A naive function would then end up incrementing the state multiple
times, probably leading to an error.
MPSStateBatchIncrementReadCount() will efficiently increment the readCounts of each object in the batch only once, avoiding this problem.
Parameters:
batch The MPSStateBatch to increment
amount The value to add to the read count for each unique state in the batch
Returns:
The number of different objects in the batch
NSUInteger void MPSStateBatchSynchronize (MPSStateBatch *__nonnull batch, __nonnull id< MTLCommandBuffer > cmdBuf)
