<p class="MsoNormal"><span style="font-family:"Times New Roman",serif">Hello all,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman",serif"> I need help in understanding the output from -log_summary for the GPU related columns. I am currently simply setting -vec_type seqcuda which I believe performs the vector operations on
the GPU. With -vec_type seqcuda, I presumed all vector operations are being done on the GPU. So, only the GPU MFlops will be logged, and CPU MFlops will be zero. But, -log_summary reports Mflops for both CPU and GPU. I do not understand why Mflops are shown
both for CPU and GPU? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman",serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman",serif">What is the meaning of the last column – percent flops on the GPU? For instance, some operations such as VecDot show 100 %F, while others like VecAXPY have less. What is the meaning of this?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman",serif"><o:p> </o:p></span></p>
