I start to design a C langage software based on CPU+GPU programming. The idea is to offload the processing on GPU when the tasks become heavy for some part of the software. I read the Gen8 paper talking about CPU+GPU shared ring memory. I look for information on how to program an application to use theses features. Could you recommend me some API, debugging tools, cache layers (L1, L2, L3) tools to visualize, investigate how the software behave on theses layers.</P> <P style="margin-bottom: 0px; border: 0px; font-size: 13px; font-family: intel-clear, arial, helvetica, 'helvetica neue', verdana, sans-serif; vertical-align: baseline; color: rgb(61, 61, 61); line-height: 19.5px;">I currently use a MacBook Air</P> <P style="margin-bottom: 0px; border: 0px; font-size: 13px; font-family: intel-clear, arial, helvetica, 'helvetica neue', verdana, sans-serif; vertical-align: baseline; color: rgb(61, 61, 61); line-height: 19.5px;">(</P> <P class="p1"><SPAN class="s1">Device Intel(R) Core(TM) i5-4260U CPU @ 1.40GHz supports OpenCL 1.2&nbsp;</SPAN></P> <P class="p1"><SPAN style="font-size: 1em; line-height: 1.5;">Device HD Graphics 5000 supports OpenCL 1.2</SPAN></P> <P class="p1"><SPAN style="font-size: 1em; line-height: 1.5;">)</SPAN></P> <P style="margin-bottom: 0px; border: 0px; font-size: 13px; font-family: intel-clear, arial, helvetica, 'helvetica neue', verdana, sans-serif; vertical-align: baseline; color: rgb(61, 61, 61); line-height: 19.5px;">Sorry for such a beginner question</P> Wed, 18 Feb 2015 09:40:28 GMT https://community.intel.com/t5/Software-Tuning-Performance/CPU-GPU-ring-programming/m-p/1013762#M3826 SChbi 2015-02-18T09:40:28Z https://community.intel.com/t5/Software-Tuning-Performance/CPU-GPU-ring-programming/m-p/1013763#M3827 <P>I cannot speak about the Mac OS , but at least I can recommend you VTune amplifier which can profile and monitor software performance very efficiently.</P> <P>By CPU-GPU ring programming do you mean heterogeneous &nbsp;programming model?</P> <P>&nbsp;</P> Thu, 19 Feb 2015 07:30:13 GMT https://community.intel.com/t5/Software-Tuning-Performance/CPU-GPU-ring-programming/m-p/1013763#M3827 Bernard 2015-02-19T07:30:13Z
