I hope autovectorization is disabled passing flag setting for null optimizin but that wouldn't be fair also..</DIV><DIV>*What the expected frecuency of updates of alpha version till release of commercial product i.e. we can expect quarterly updates for example?</DIV> Tue, 16 Nov 2010 16:43:44 GMT https://community.intel.com/t5/OpenCL-for-CPU/Lots-of-questions/m-p/784816#M482 oscarbg 2010-11-16T16:43:44Z https://community.intel.com/t5/OpenCL-for-CPU/Lots-of-questions/m-p/784817#M483 <P class="Default"><I>Thanks for sharing your feedback.</I></P> <P class="Default"><I>The current version of the Intel OpenCL SDK is only a technology preview.
