It's ATI OpenCL builld update intended to replace rev456 OpenCL build and rev 449 OpenCL+Brook build.
Hardware requirements are the same as for rev456 OpenCL build (look old release notes here:
http://lunatics.kwsn.net/12-gpu-crunching/astropulse-for-ati-gpus-released.msg31201.html#msg31201 )
New command line switches:
-hp - sets high priority class
-no_cpu_lock - disables affinity setting
-instances_per_device N - will allow running N copies per each supported GPU device (don't forget to set <count> field in app_info to 1/N to instruct BOINC to launch N tasks per GPU).
-unroll N -sets DATA_CHUNK_UNROLL variable to N. This allows to do N data chunks per FindSinglePulse kernel call improving (in most cases) performance but increasing GPU memory requirements. On low-end GPUs it may be worth to use lower values. Default setted to 10 as in r456 (there it was hardwired to 10).
Known issues:
Don't forget to finish current AP task before upgrade. Or you will need to manually update CL file not only in SETI project directory but in corresponding slot directory too. BOINC doesn't do this, design flaw IMHO.
Double check if your config (GPU+driver) has OpenCL support in case of mobility GPU. Ask Ati for OpenCL support if not.
