Command-Line Options
Running the cache allocation sample with the
-h
option yields the following usage message:Usage: tcc_cache_allocation_sample -l N [--sleep N | --stress | --nostress] [-p N] [-c] [-i N]Option | Description |
|---|---|
-p | --cpuid N | Specify the requested core. Default: 3. |
-l | --latency N | Required. Specify the maximum tolerable latency for a single cache
line access in N nanoseconds. |
--sleep N |--stress |--nostress | Optional. Select one of these options: --sleep N Period between iterations in N nanoseconds. Select this option when you want to run your own noisy neighbor.--stress Run the sample’s provided noisy neighbor on core
3 (default).--nostress Do not run the sample’s provided noisy neighbor and run workload iterations continuously without sleep in between. |
-c | --collect | Optional. Enable measurement result collection if
INTEL_LIBITTNOTIFY64 was not set via environment. |
-i | --iterations N | Optional. Execute N iterations of the main loop to gather more
precise timing statistics. (default: 100) |
-h | --help | Optional. Print command-line help. |
An alternative to
-c | --collect
is to use the INTEL_LIBITTNOTIFY64
environment variable to set the collector library.Usage: INTEL_LIBITTNOTIFY64=libtcc_collector.so tcc_cache_allocation_sample -l N [--sleep N | --stress | --nostress] [-p N] [-c] [-i N]
