Improvement of cudppSegmentedScan with additional CUDPP_UCHAR #80

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Hi,

as pointed out in this thread: 
http://groups.google.com/group/cudpp/browse_thread/thread/3788d4644114a6ff
i am running into trouble when using CUDPP_UCHAR as type for a segmented scan.

The corresponding line of code failing is:
CUDA_SAFE_CALL(cudaMalloc((void**) &(plan->m_blockSums[level]), numBlocks * 
elementSize)); 

Am i doing something wrong or i that type not implemented yet? If not i would 
like to ask for an additional data type for cudppSegmentedScan (and others?) 
because i think a 4 byte type is way to much for indicating zeros and ones.

Regards, Ullrich

Currently CUDPP_UCHAR (and CUDPP_CHAR) are only supported in cudppRadixSort (in 
trunk) and cudppCompact (in 1.1.1).  I'm marking this issue as an enhancement 
request for the 2.1 release.
