If you'd like to use your Apple Mac with OS X for some numerical computation, this site could be useful to you. Most of these packages have been compiled/tested on several version of OS X and XCode Tools. Feel free to contact me with questions or problems!

Computation Tools :: C/Fortran

Mac OS 8.6 to 9.2 (and Mac OS X 10.1) are no longer supported but you can find the last supported release of R for these systems (which is R 1.7.1) here. Mac os x 10.8 free download. HPC on Mac OS X Tools for High Performance Scientific Computation on Mac OS X. Fortran (92) Visual Basic (86) Lazarus (85). Simply Fortran 3.13 for Mac is available as a free download on our software library. This software for Mac OS X was originally designed by Approximatrix, LLC. This Mac download was scanned by our antivirus and was rated as clean. Simply Fortran for Mac belongs to Developer Tools. The latest setup package occupies 103.6 MB on disk. I applied the students free Intel Parallel Studio XE Composer Edition for Fortran OS X and got serial number. I download the 2016 version but it's 'mfcompxe2016.0.033.app' and double-click couldn't work to install it.

GCC 4, 5, 7, 8, 9, 10 (auto-vectorizing gcc with OpenMP):
Compiled using source code from the GNU servers. This contains current versions (8.3 is the stable release) of gfortran (free, open source, GNU Fortran 95 compiler), gcc (GNU C) and g++ (GNU C++) compilers that can perform auto-vectorization (i.e. modify code to take advantage of AltiVec/SSE, automatically) and other sophisticated optimizations like OpenMP. For more information, see this webpage. Download my binaries, and cd to the download folder. Then gunzip gcc-10.2-bin.tar.gz (if your browser didn't do so already) and then sudo tar -xvf gcc-10.2-bin.tar -C /. It installs everything in /usr/local. You can invoke the Fortran 95 compiler by simply typing gfortran. You will also need to have Apple's XCode Tools installed from the Mac App Store. With XCode 4 or better you will need to download the command-line tools as an additional step. You will find the option to download the command-line tools in XCode's Preferences. On 10.9 Mavericks or higher, you can get the command-line tools by simply typing xcode-select --install. And on Catalina, you may have to specify an additional include and library path -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib for the compiler to find the system headers and libraries.

A modern Fortran development environment for Apple macOS and Mac OS X. Package includes the GNU Fortran compiler, an advanced code editor, and an integrated debugger for fast and easy installation. Try it free for 30 days! Also available for Windows and GNU/Linux. F2C based Fortran: This is the oldest Fortran compiler available for OS X. Its been around since OS X was in a public beta state. Download this shell script: buildf2c, type chmod +x buildf2c and then sudo./buildf2c. The script will grab f2c source from Netlib repositories and install a f2c based compiler in /usr/local/.

g77 3.4 :
This is the FINAL release of g77 (version 3.4 compiler). Future versions of GCC will have gfortran (see above). Download my binaries, and cd to the download folder. Then gunzip g77-bin.tar.gz (if your browser didn't do so already) and sudo tar -xvf g77-bin.tar -C /. It installs everything in /usr/local. You will need to have Apple's Developer Tools installed. They are included on the retail DVD version of OS X and also available as a free download from Apple's Developer Site. Please install the most current version of Developer Tools. Thanks to James Wookey for the Intel Mac version of g77.
Binaries: g77-bin.tar.gz (PowerPC only), g77-intel-bin.tar.gz (Intel Mac only), updated October 2006.

Computation Tools :: Octave

Octave:
Octave is an open source, Matlab-like numerical analysis software package that is very popular among scientists and engineers. The good folks over at Octave-Forge provide an OS X style Octave application, with drag and drop installation! I recommend their binaries (links below).
Source: Octave
Binaries: Octave application, updated May 2011.

Computation Tools :: Cactus, RNPL, etc.

Einstein Toolkit:
The Einstein Toolkit is an open-source software framework specifically targeted to the research area of numerical relativity and astrophysics. The broad aim of the toolkit is to provide the core computational tools that enable scientific research in this area, and take advantage of emerging petascale computers and advanced cyberinfrastructure.The Einstein Toolkit compiles and runs great on Mac OS X. A critical component of this toolkit is the Cactus Computing Toolkit (see below).

CactusCode (Numerical Computing Toolkit):
Cactus is an open source problem solving environment designed forscientists and engineers. Its modular structure ('thorns') easilyenables parallel computation across different architectures andcollaborative code development between different groups. It ismainly used for solving complicated PDE's. It highly portable, andhas some really remarkable features like observing and even'controlling' or 'steering' a running simulation using an ordinaryweb browser! Here is a link to a perpetual demo running at LSU Cactus Demo. Check it out!Cactus compiles and runs great on Mac OS X.

RNPL (Rapid Numerical Prototyping Language):
This is a great tool that takes as input details about the form ofan equation (usually a partial differential equation), and someparameters .. and then spits out a C or FORTRAN Code that solvesthe equation numerically using established iterative numericaltechniques. RNPL can also be used for producing skeleton programsand for converting existing programs. Download the source, compileand install. This source has been modified to compile with OS X. Orget my binary distribution. You probably want to install this in/usr/local, to do so gunzip rnpl-bin.tar.gz (if your browser didn't do so already) and then sudo tar -xvf rnpl-bin.tar -C / and you are done! You will need to use the F77 flag: -fno-second-underscore, for RNPL generated F77 codes to compile properly.
Source: rnpl.tar.gz
Binaries: rnpl-bin.tar.gz, updated 2003.

The GRAVSIM Package:
GRAVSIM is a package that contains an ever evolving and hopefully growing set of gravitational N body solvers. These solvers attempt to track the motion of a set of bodies moving under the influence of gravity. They are used in many areas of astrophysical study including planetary motion, star cluster formation and stability and galactic formation, stability and interactions (i.e. colliding galaxies). This package is highly AltiVec and DP optimized!

Xmgr Grace:
This is a very easy to use, open-source, X11 based, plotting tool. I used it during my graduate school days and still love it. Its excellent especially for students and free! Note: I didnot create this binary, but I have tested it on both Intel and PPC Macs. It works very well. Move the Grace application to the system /Applications folder for it to function correctly.By the way, if you are looking for a nice, easy to use, 2D and 3D,plotting package for OS X, try pro Fit. It works great. They have a free trial version, that is not time-limited and is full-featured. It just has some restrictions on the volume of data you can make it handle. Even the full version is very inexpensive.
