Release of version 1.1.4 of Tonatiuh

We just released version 1.1.4 of Tonatiuh. This new release version of Tonatiuh is a minor release of the program. It corrects some memory leaks and other minor bugs of the program and incorporates a large number of internal code improvements targeted to improve the program's speed in all platforms.

This is the first release of Tonatiuh for which, in addition to the 32-bit versions of the program targeted to Windows, Linux, and Mac, we are also releasing a 64-bit binary of the program targeted to Linux.

In the following weeks we will be adding the corresponding 64-bit version of the program targeted to Windows and Mac.

If you already installed in your computer Tonatiuh release 1.1.3, you do not need to download the installer for the new release of the program, just start Tonaiuh's release 1.1.3, go the the Help menu in the menu bar, click on “Check for updates” option, and follow the instructions that will appear on the screen. Of course, for that to work you have to be connected to Internet.

As shown in the following figure, this release is faster than previous releases of the program. Under Windows, it achieves a 22.4% reduction in the average time it needs to cast 6 million rays while simulating the optical behaviour of NREL's Solar Furnace in the three different computers in which the program was tested. Under Linux this average time reduction reached 16.7%.
