i have question local memory usage across work items: i have workgroup 256 work items in it. assign k bytes of local memory per work item. so, create local byte array of size 256 * k, , assign 1 region of size k each work item. in code, each work item accesses own region in array. can guaranteed work items not somehow access work items region? given fact local memory shared across half wavefronts? the reason ask seeing sort of corruption, not sure if code bug, or problem design; i.e. using shared local array, shared among work items. given fact local memory shared across half wavefronts i not sure mean that, opencl spec states local memory shared across work-group . there no such concept "half wavefront" (nor wavefront) far standard concerned. any memory corruption may notice can have been introduced own code: responsibility kernels not exhibit data races.

trying convert latin1 mysql db utf8, tried following: dump db run iconv -f latin1 -t utf8 on resulting file import fresh db utf8 default encoding this mostly works except... some letters converted wrong (an example: uppercase accented 'u' becomes garbled sequence starting question mark). conversion taking place (od query result shows 2 byte sequence latin1 byte was) , te latin1 version alright. while have far been unsystematic in isolating problem (late night; under deadline; etc.) weirdness of issue kills me: why fail on some letters , not all? client connection? column charset? why not getting diagnostics? i'm stymied. sure, can work on isolating issue , details, thought maybe ran , can recognize (admittedly rather poor) description. cheers the data may have been stored latin1 it's possible ever client used dump data has exported utf-8. open dump file in decent text editor (notepad++, textwrangler, atom) , check encoding allows character...
