The first part of the command. With the new auto-rebuild feature, the sampling driver detects the kernel update and automatically attempts to rebuild and load the driver. Using spell , the words that are not recognized will be placed at the top of the file. Please note that To profile applications with user APIs on the Intel Xeon Phi coprocessor, environment variables that control collection must be propagated from the host to the Intel Xeon Phi coprocessor card. Custom Groupings Many new ways to group and order the performance data, including custom groupings in grid views and new groupings in the timeline pane. Delete Char Delete the character the cursor is on. Hardware event-based analysis types now support collection data limit Hardware event-based analysis types now support the collection data limit to prevent collecting large amounts of data, which may slow down data processing.

To control collection from the command line — pause 360s or detach you can use commands from host as follows:. Explore the serial vs parallel time and the top OpenMP regions by potential gain. Command line reports now provide General Exploration metrics summary for hardware event-based sampling analysis results providing a high-level overview of performance problems.
If only one domain is available, the drop-down menu is grayed out. Ability to cache source files and explore collected performance statistics later even if the source file has been changed Save your source files in the cache.
FreeBSD Manual Pages
They look at whatever they find, and sure, they’re going to ask their questions about the lil’ penguin and his OS, but they are also thinking to themselves, is this going to be fun for me? Import externally collected data Increase analysis by importing externally collected data into existing results.
Exposed the CPU Utilization metric by physical cores on processors that support proper hardware events.
When an OpenMP region contains multiple constructs with barriers e. Update 1 Release Notes Overview: One of the most historically important artifacts to come from the home computer telecommunications revolution was shareware CDs, compact discs put out by companies containing hundreds of megabytes of shareware.

The Memory Access Analysis has been improved. The Ivy Bridge family of processors no longer has separate advanced analysis types, only General Ed and Bandwidth.
There are no restrictions on the length of lines, and no formatting takes place. Exclusive launch mode helps prevent running more than one collection per node, which is a limitation of EBS profiling.
The old information would have to be deleted by the user. Is that a good idea? But it is far more common for an OpenMP program to consist of a sequence of parallel regions interspersed with serial code. With the VTune Amplifier, you can easily correlate the frame data in the Timeline pane and grid view.
When synchronization objects are used inside a parallel region, threads can wait on a lock release, contending with other threads for a shared resource. For proper resolving symbol information, use – search-dir action-option to specify directories that should be searched for binary executables and dynamic libraries and symbol files typically. Register for license key Magnolia Enterprise Edition is linix for a free day trial. Found at a flea market, but probably 630ss included as 630e cover disc inside an issue of PC Magazine.
It is always in text insertion mode unless there is a prompt at the bottom of the terminal, or a menu present in a box in the middle of the terminal. For more complete information about compiler optimizations, see our Optimization Notice. Explore the logical program flow of OpenMP regions. Source Function Stack grouping level enabling more 63s result comparison in the Top-down Tree pane Use Source Function Stack de level in the Top-down Tree pane for enabling more accurate result comparison for recompiled binary files when addresses of the same source function or same loop are different, like in these cases: The cell is highlighted pink when there is ilnux potential tuning opportunity.
Besides reporting the potential gain metric in absolute elapsed time, the VTune Amplifier display breaks down the impact of various issues by percentage of total application elapsed time.
As prerequisites you need to install collectors on the remote target and enable pasword-less SSH access to the target. A license key will be sent to the email address you provide.
Due to recent published erratasystems may have this feature disabled, by default. Use the ‘-stack-depth’ collector knob in the command line and the corresponding GUI control “Stack size” in the Custom Analysis dialog for the hardware-based sampling. Share Tweet Share Send.
