| Take This Short Tutorial | Learn To Do This | |
|---|---|---|
| Finding Hotspots |
Sample code: <install-dir>/samples/<locale>/C++/tachyon_vtune_amp_xe.tgz |
Identify where your application is spending time, detect the most time-consuming program units and how they were called. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/find_hotspots/C++/index.htm. |
|
Sample code: <install-dir>/samples/<locale>/Fortran/nqueens_fortran.zip |
Identify the most time-consuming program units, analyze thread parallelism on available logical CPU cores, and identify synchronization objects preventing parallelism. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/find_hotspots/Fortran/index.htm. |
|
| Finding Hotspots on the Intel® Xeon Phi™ Coprocessor |
Sample code: <install-dir>/samples/<locale>/C++/matrix_vtune_amp_xe.tgz |
Identify where your native Intel Xeon Phi coprocessor-based application is spending time, estimate code efficiency by analyzing hardware event-based metrics. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/find_lw_hotspots/C++/index.htm. |
| Analyzing Locks and Waits |
Sample code: <install-dir>/samples/<locale>/C++/tachyon_vtune_amp_xe.tgz |
Identify locks and waits preventing parallelization. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/analyze_locks/C++/index.htm. |
| Identifying Hardware Issues |
Sample code: <install-dir>/samples/<locale>/C++/matrix_vtune_amp_xe.tgz |
Identify the hardware-related issues in your application such as data sharing, cache misses, branch misprediction, and others. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/identify_hw_issues/C++/index.htm. |
| Analyzing Disk Input/Output Waits |
Sample code: <install-dir>/samples/<locale>/C++/diskio_vtune_amp_xe.tgz |
Analyze an I/O bound application that uses the system file cache and user buffer to work with the I/O device. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/analyze_disk_io/C++/index.htm.
|
| Identifying False Sharing |
Sample code: <install-dir>/samples/<locale>/C++/linear_regression.tgz |
Identify false sharing. Alternative access method: Launch the tutorial from <install-dir>/documentation/<locale>/tutorials/identify_false_sharing/C/index.htm.
