two questions, timing and memory  two questions, timing and
memory  Ritratto di King Crimson  Hi all,  I'm testing my code
on MIC using pragma offload + openmp model, and I have 2
questions so far.  1. when we use OFFLOAD_REPORT to do the
timing, is it true that the data transfer time can be derived by
subtracting  "MIC time" from "CPU time"? So in this context, CPU
time refers to the actual total time of the offloaded code,
right?  2. some SIMT accelerator has high latency of global
memory acess and the access has to be coalesced to prevent over-
fetch, I'm wondering if these 2 problems exist on MIC, and what
issues I should pay attention to with regard to efficient global
data access? Specifically, my code has a non-vectorized (threads
may execute totally different instructions most of the
time), embarrassingly parallel nature, and global memory access
follows a very random, scattered pattern. Will
this potentially cause any performance penalty?  Thanks for
clarifications!  The keeper of the city keys Put sh
