•Intel(R) Processor Graphics Gen9 (formerly Skylake) and newer
•Intel® Iris® Xe Graphics
•Intel® Data Center GPU Flex Series
•Intel® Data Center GPU Max Series
•Ubuntu 20.04 with Intel(R) Iris(R) Plus Graphics 655
1.Runtime API Tracing
•for OpenCL(TM)
•for oneAPI Level Zero (Level Zero)
•for OpenMP*
2.Device Activity Tracing
•for OpenCL(TM)
•unitrace - unified tracing and profiling tool. In addition to Level Zero and/or OpenCL, this tool is capable of profiling software layers in the software stack, for example, SYCL and plugins, oneCCL, MPI etc., for scale-up and scale-out applications. It also supports profiling hardware metrics (including instruction-level EU stalls) and software events at the same time.
•onetrace - host and device tracing tool for OpenCL(TM) and Level Zero backends with support of DPC++ (both for CPU and GPU) and OpenMP* GPU offload;
•oneprof - GPU HW metrics collection tool for OpenCL(TM) and Level Zero backends with support of DPC++ and OpenMP* GPU offload;
•ze_tracer - "Swiss army knife" for Level Zero API call tracing and profiling (former ze_intercept);
•cl_tracer - "Swiss army knife" for OpenCL(TM) API call tracing and profiling;
•gpuinfo - provides basic information about the GPUs installed in a system, and the list of HW metrics one can collect for it;
•tools for OpenCL(TM), DPC++ (with OpenCL(TM) backend) and OpenMP* GPU offload (with OpenCL(TM) backend):
•cl_hot_functions - provides a list of hottest OpenCL(TM) API calls by backend (CPU and GPU);
•cl_hot_kernels - provides a list of hottest OpenCL(TM) kernels by backend (CPU and GPU);
•cl_debug_info - prints source and assembly (GEN ISA) for kernels on GPU;
•cl_gpu_metrics - provides a list of hottest OpenCL(TM) GPU kernels along with percent of cycles it was active, stall and idle (based on continuous metrics collection mode);
•cl_gpu_query - provides a list of hottest OpenCL(TM) GPU kernels along with percent of cycles it was active, stall and idle (based on query metrics collection mode);
•CMake (version 3.12 and above)
•Git (version 1.8 and above)
•Python (version 3.6 and above)
•On Linux one have to be a part of video (Ubuntu 18 and below) or render (Ubuntu 19 and above) user group to do any computations on Intel(R) Processor Graphics:
•OpenCL(TM) ICD Loader and Headers
•to use non-standard path to OpenCL ICD library one may add it into LD_LIBRARY_PATH:
In general, to build samples one need to perform the following steps (specific instructions for particular sample can be found on sample description page):
To point out to specific headers and libraries one may use -DCMAKE_INCLUDE_PATH and -DCMAKE_LIBRARY_PATH options correspondingly, e.g.:
