It also describes the theory behind optimizing in general. While these variables are not standardized, their use is essentially ubiquitous and any correctly written build should understand these for passing extra or custom options when it invokes the compiler. See the GNU make info page for a list of some of the commonly used variables in this category. They can be used to decrease the amount of debug messages for a program, increase error warning levels and, of course, to optimize the code produced. The GCC manual maintains a complete list of available options and their purposes. Variables set in this file will be exported to the environment of programs invoked by portage such that all packages will be compiled using these options as a base. Almost every system should be configured in this manner. Don’t set them arbitrarily. Individual packages further modify these options either in the ebuild or the build system itself to generate the final set of flags used when invoking the compiler. Being aware of the risks involved, take a look at some sane, safe optimizations.
Edit this page. R is a high-level, expressive language. But that expressivity comes at a price: speed. Next, check out the Rcpp book and the other resources listed in learning more.
Retiming and Fast Forward compilation available only for Intel® Stratix® 10 and For designs that fail timing, all paths with negative slack are put in high-speed.
Puppet manifests are concise because they can express variation between nodes with conditional logic, templates, and functions. Puppet resolves these on the master and gives the agent a specific catalog. Manifests and modules, including associated templates and file sources. When an agent requests a catalog, it sends four pieces of information to the master:. This is the one item not used by Puppet apply.
Puppet uses two main kinds of external data during catalog compilation:. For more information about ENCs, see Writing external node classifiers. Manifests and modules are at the center of a Puppet deployment, including the main manifest, modules downloaded from the Forge , and modules written specifically for your site. For more information about manifests and modules, see The main manifest directory and Module fundamentals.
Some items are presented out of order for the sake of clarity.

SLIME has fancy commands for compiling functions, files, and packages. The fancy part is that notes and warnings offered by the Lisp compiler are intercepted and annotated directly onto the corresponding expressions in the Lisp source buffer. Give it a try to see what this means. Compile the top-level form at point. The region blinks shortly to give some feedback which part was chosen.
the build. Typically their main effect is on the speed on the build. If you’re trying to use –save_temps to debug a failed compilation, you may need to also use.
This should make the selection easier when there are lots of boards loaded in the IDE. Should improve network board detection. This will make some libraries to compile again. This is the bootloader installed on new Arduino Nano boards. This solves a long standing issue with “Burn bootloader”. Thanks xloem.

So, how can I prevent the JIT compilation here?
Everybody loves a trip to the dyno, but compilations like this will certainly have you thinking twice about either running your own car or where.
Take a look at Build system — Installation if you haven’t installed the Build system yet. Sources in development branch change frequently. It is recommended that you work with the latest sources. Installing in context of. Also, after you have been developing for a while, and your copy of the repository is getting behind, running feeds update -a will pull the latest updates for the feeds. Each branch contains the baseline code for the release version e. Each branch is intended to contain stable code with carefully selected fixes and updates backported from the development branch.
To use a branch, you should first clone the Git repository using the git clone command shown above. Then move to the branch by using the git checkout command. When changing branches, it is recommended to perform a thorough scrub of your source tree by using the make distclean command. This ensures that your source tree does not contain any build artifacts or configuration files from previous build runs.

You Benchmark is not very usefull: you test mostly the speed of and UUID. Also it “just” allocates a PoJo (as it seems), what results would you.
You can configure how you want a compiler to process the code you work on. For example, you can increase the speed of the compilation process, configure the automatic build, process annotations during the compilation time, and so on. IntelliJ IDEA offers you extensive compilation options to tune the compilation process in general and configure settings for specific compilers. On the Compiler page , configure settings that are related to any compilation and build process.
For example, you can set the automatic compilation for your project. You can exclude certain paths from compilation or re-include some files or classes that were excluded by you earlier.

This happens with both Swift 4. I can get it to stop hanging by either:. Does anyone know what may be going on here? Is there a likely culprit in my codebase or is this just a compiler bug? However who knows when this will be part of Xcode. Most probably only when Swift 5.

This is a short guide to features present in Numba that can help with obtaining the best performance from code. Two examples are used, both are entirely contrived and exist purely for pedagogical reasons to motivate discussion. All performance numbers are indicative only and unless otherwise stated were taken from running on an Intel i CPU 4 hardware threads with an input of np. A reasonably effective approach to achieving high performance code is to profile the code running with real data and use that to guide performance tuning.
The information presented here is to demonstrate features, not to act as canonical guidance! A common pattern is to decorate functions with jit as this is the most flexible decorator offered by Numba. Whilst the use of looplifting in object mode can enable some performance increase, getting functions to compile under no python mode is really the key to good performance. Whilst NumPy has developed a strong idiom around the use of vector operations, Numba is perfectly happy with loops too.
For example:. The above run at almost identical speeds when decorated with njit , without the decorator the vectorized function is a couple of orders of magnitude faster. In certain classes of applications strict IEEE compliance is less important. As a result it is possible to relax some numerical rigour with view of gaining additional performance.
The way to achieve this behaviour in Numba is through the use of the fastmath keyword argument:.
This page explains why this can happen and how to fix it. Here are some ways to get around this:. See this article for detailed suggestions on handling large images. TikZ and pgfplots produce great graphics, but they can take a long time to compile.

The following sections describe the options available during a build. When –long is used on a help command, the on-line help messages provide summary information about the meaning, type and default value for each option. Most options can only be specified once. When specified multiple times, the last instance wins. Options that can be specified multiple times are identified in the on-line help with the text ‘may be used multiple times’.
This option specifies the set of directories that are searched to find the BUILD file for a given package. Bazel finds its packages by searching the package path. This is a colon separated ordered list of bazel directories, each being the root of a partial source tree. If you use a non-default package path, we recommend that you specify it in your Bazel configuration file for convenience. Bazel doesn’t require any packages to be in the current directory , so you can do a build from an empty bazel workspace if all the necessary packages can be found somewhere else on the package path.
