Solid appbut I wish it could have messaging like the iPhone and Android versions. Haven't really used it yet, but 4 Stars just for giving us a Windows Phone app!
Useful, but very buggy and lacks messaging like IOS and android. Useless on NCL Sun. Can't find ship. I wish useless apps like this would be pulled from the store. Practically useless. Too many crashes to count and clunky. Great concept but needs further enhancements. Add more content descriptions of ship board events like you do with excursions.
Great App. No more waiting inline to book tours. I love the restaurants feature where I can check all the menus and reserve a table anytime I want. Did not connect to the Dawn, last week. Thanx for nothing, except the countdown clock. Did not work for my windows 8 phone! No on board support!

NCCLon the other hand, implements each collective in a single kernel handling both communication and computation operations. This allows for fast synchronization and minimizes the resources needed to reach peak bandwidth.
NCCL conveniently removes the need for developers to optimize their applications for specific machines. NCCL has found great application in deep learning frameworks, where the AllReduce collective is heavily used for neural network training.
Using NCCL is similar to using any other library in your code. For example:. If you are using NCCL 1. NCCL 2. In addition, NCCL 2. Group API is not required in this case. The recvbuff argument has been moved after the sendbuff argument to be consistent with all the other operations. Refer to the NCCL open source documentation for additional support.

NCCL is not a full-blown parallel programming framework; rather, it is a library focused on accelerating collective communication primitives. Next to performance, ease of programming was the primary consideration in the design of NCCL.
Software Requirements. Ensure your environment meets the following software requirements: glibc 2. Hardware Requirements. Installing NCCL. There are two repositories available; a local repository and a network repository. Choosing the latter is recommended to easily retrieve upgrades when newer versions are posted. Note: If you are using the network repository, the following command will upgrade CUDA to the latest version.
If you prefer to keep an older version of CUDA, specify a specific version, for example: sudo yum install libnccl Other Distributions.Choosing the right NCL binary for your Linux system Dealing with missing libgfortran issue Dealing with missing lib xxx.
Secondly it's important to try to match your flavor of Linux if possible, and then match your version of gcc as close as possible. If your flavor of Linux or "bitness" doesn't match, then you can usually use one of the other ones. If you have a Ubuntu system, try a Debian binary. If you run into a problem, please email ncl-install you must subscribe first.
Dealing with missing libgfortran issue For most Linux binaries, NCL was built using gcc and gfortran. This may cause a dependency on a file called "libgfortran.
If you have a different version of gfortran installed on your system than what NCL was built with, then you may get an error message that "libgfortran. If you see this, then you can try one of these things: Trying googling part of the error message that you're getting, along the flavor of LINUX. You will usually get several hits with lots of good suggestions.
Install the version of gfortran that your version of NCL was built with. It is possible to have multiple versions of gfortran installed on the same system without conflict. If you are using Debian or Ubuntu, you can use the "apt-file" command you may need to install it first to search for a package that contains the missing libgfortran file "libgfortran. You can try the "locate" command. For example if the file is "libgfortran. However, if you just can't get it to work, then read on. For example, if "libgfortran.
You need to be a member in order to post. Dealing with missing lib xxx. If you try to run "ncl" and get one or more errors about not finding "lib xxx. To look for a particular missing file, try using the "locate" command: locate libcrypto.
If you can't find this file, then you may need to install OpenSSL on your system. For example, on some Linux systems, you may be able to type: yum install openssl or apt-get openssl apt-get install openssl For further information and more links about where to find software, see the previous section on dealing with the missing libgfortran issue. Installing other software for Linux systems cairo, X11, and other dependent libraries - you need an X11 server in order to run ncl and display output to an X11 library, and you need the cairo, X11, and other development libraries in order to build NCL from source code.
Getting the development libraries on your system depends on what kind of Linux system you have. The commands below are samples of the types of commands you can use to install the required software. You can install these shells with a command like: apt-get install csh or yum install tcsh If any of these instructions are out-of-date, please send email to ncl-install.There are three main steps: Download the appropriate NCL binary Extract files Set up your environment If you've read over this document and still have problems, then please send email to ncl-install ucar.

Extract files from gzipped tar file The precompiled binary that you download will either be a compressed tar file xxxx tar.
Problem with libgfortran. Missing a "libgomp" library? Not sure which binary to download? In most cases, csh is on your system by default.
If it is not, and you are on a Linux system, you can try installing it with: sudo apt-get install csh or yum install tcsh tcsh is an enhanced and compatible version of csh.
If you are on Cygwin, see the instructions on the Cygwin page for installing csh. You can quickly test if NCL is installed properly by typing: ng4ex xy01n -clean The ng4ex command will copy an NCL script called xy01n. An X11 window should pop up with an XY plot. Click on this plot with your left mouse button to advance and thus close the frame.
If you only plan to use NCL, it is not important that this command is successful. If you run "ncl" and get error messages about missing lib xxx.Please read these instructions all the way through before starting the installation.
See the next section for more details. Enable and run the Linux Bash shell Once you have Windows 10 installed, you need to enable the Linux Bash shell and then run it. We found this useful article on howtogeek. Be sure to read through the section on how to run the bash. Using Linux makes this easy, because you can use the "apt-get" command to install the required packages. From the Linux bash window that you opened earlier, type the following commands to install the required packages.
You can put multiple packages on one line: sudo apt-get install csh libfontconfig gfortran libgfortran3 sudo apt-get install libxrender-dev libxdev libxrender1 sudo apt-get install libssh libgomp1 sudo apt-get install firefox imagemagick Note that the firefox and imagemagick packages are not required, but useful. Imagemagick gives you the powerful "convert" command for converting and post-processing graphical images.
The above installations can take awhile, so make sure to do this when you're not in a hurry. If you are not sure, then we recommend following these instructions anyway.
Go to the Climate Data Gateway web site. Navigate your way to the NCL Version 6. Download the binary for the bit version of NCL compiled under Debian 7. If you are unfamiliar with UNIX editors, we recommend that you use neditwhich you can install via "sudo apt-get install nedit". If you click anywhere in the window with your left mouse button, the window will go away.
If you have problems, then please review the troubleshooting section that follows. Troubleshooting problems If you are having problems running the test in the above section, then here are some troubleshooting tips: If you get an error about "ncl" not being able to find a missing "lib xxxx. If you still have problems, then send email to ncl-install ucar. You need to be a member in order to post.NCL can be installed on Mac and Linux systems via conda.
If disk space is an issue Anaconda is quite largewe recommend miniconda as this is a more minimal system that requires less disk space. Keep reading for information on how to install conda, and then how to use it to install NCL. We do not have a pure Windows version of NCL.
Follow the instructions for installing miniconda. When the installation is finished, you can test it quickly by typing the following from a UNIX terminal window: conda -V This should echo something like "conda 4. Note: you can also get the conda command by downloading and installing Anaconda. You can call it whatever you want. We don't currently have an NCL development version available, but check back here later.
The second command should pop up an "x11" window with a simple line contour plot. Click on this window to advance to the next plot there are five plots total. Send questions or problems to ncl-install email list If you are having problems installing NCL using conda or NCL doesn't appear to be working, then subscribe to ncl-install and email your issue to ncl-install ucar.
Please include the exact error message and what you were typing that caused the error.
