- This system uses 8 bytes per array element.
- -------------------------------------------------------------
- Array size = 2500000 (elements), Offset = 0 (elements)
- Memory per array = 19.1 MiB (= 0.0 GiB).
- Total memory required = 57.2 MiB (= 0.1 GiB).
- Each kernel will be executed 10 times.
- The *best* time for each kernel (excluding the first iteration)
- will be used to compute the reported bandwidth.
- -------------------------------------------------------------
- Number of Threads requested = 48
- Number of Threads counted = 48
- -------------------------------------------------------------
- Your clock granularity/precision appears to be 1 microseconds.
- Each test below will take on the order of 4989 microseconds.
- (= 4989 clock ticks)
- Increase the size of the arrays if this shows that
- you are not getting at least 20 clock ticks per test.
- -------------------------------------------------------------
- WARNING -- The above is only a rough guideline.
- For best results, please be sure you know the
- precision of your system timer.
