A 4 meses del lanzamiento del viejo Stream SDK 2.3 AMD lanza su nueva versión ahora llamada Accelerated Parallel Processing (APP) SDK 2.4, la que llega con algunas nuevas funciones y mayor rendimiento para las aplicaciones que hagan uso del API OpenCL.
PUBLICIDAD
La nueva versión 2.4 del OpenCL ICD de AMD introduce muchas novedades enfocadas a corregir problemas, añadir nuevas funciones e incrementar el rendimiento de las aplicaciones escritas para OpenCL, las que por su nauraleza no son compatibles con los drivers Catalyst 11.3 ni inferiores, siendo por el momento los Catalyst 11.4 Early Preview los únicos drivers compatibles hasta la llegada de los Catalyst 11.4 WHQL a fin de mes.
Sin mayor preámbulo aqui las novedades de APP SDK 2.4:
- Improved OpenCL runtime performance:
- Zero copy transfer of data between CPU and GPU for APUs (Windows only)
Improved PCIe transfer speed
Improved kernel launch times
