In place operations

[Shahar]

Hey 

I'd like to know whether or not CUB library support in place operation ? 

I'm using the 

cub::DeviceSelect::Flagged operation. 

I'd like to know if the input and output variable can be the same array 

Thanks in advence

Yes, you can!  Thanks for asking about this; I forgot to add in-place operation as a "feature" of

• cub::DeviceScan
  
• cub::DeviceSelect
  
• cub::DeviceReduce::ReduceByKey
  
• cub::DeviceReduce::RunLengthEncode
  

It is not true for

• cub::DevicePartition
  

I will update the doc for the next release.

Cheers,

Duane

Does the newest release still support in-place operations for these functions?

Thanks,

Nick

This addition to the documentation has not been done. It would be important to do it as in-place operation are important to limit memory usage, but we cannot use them if we are not sure they are supported. Thank you in advance.
