Hi all, Suppose a code is tuned on a specific system (e.g Intel Xeon based using Vtune or Trace Collector). Then to how much extent this tuning will be useful if this code is compiled and run on some other system (e.g. AMD Opteron based)? Means whether the code tuning performed at one system (possibly with a Profiler specific for that system) is almost equivalently good on another system ? Or we need to tune it again (possibly using a Profiler specific to the new system).
Thank you for your attention. A.Ali
