Scientific Linux is a recompiled distribution of Red Hat Enterprise Linux, jointly developed by the Fermi National Accelerator Laboratory and the European Organization for Nuclear Research, or as it is known, European Organization for Nuclear Research (CERN).
Scientific Linux is relatively unknown, but it is one of the best clones of Red Hat Enterprise Linux. Its name, though it shows that it is only for scientists, is unfair. Naturally, distribution is not only scientists, it took it because its development and maintenance are done by scientific organizations.
Although the distribution aims to be fully compatible with Red Hat Enterprise Linux, it also provides additional packages not found in RHEL. The most notable of these are various file systems, such as Cluster Suite and Global File System (GFS). , FUSE, OpenAFS, Squashfs and Unionfs. Supports wireless networking with Intel wireless firmware, MadWiFi and NDISwrapper. It comes with Sun Java and the Java Development Kit (JDK), along with the lightweight IceWM window manager. It features R – a language for statistical computing, as well as the Alpine email client.
Scientific Linux 7.2 Release Notes
I tested the distribution on the system I'm using. Dual boot with Manjaro Linux which I particularly like because of the rolling platform it uses. I decided to add a system like SL 7.2 first because I wanted some characteristics server that does not have Manjaro and then because it is a clone of Red Hat. 
Of course, to get the dual boot in my hands I had to use some tweaks. After installing Scientific Linux 7.2, the boot of the system did not see Manjaro at all, so before I went to Scientific Linux I chose boot from BIOS where the main system of the computer appeared.
So, from Manjaro I opened directory / boot as root
I searched the dirs that contained the boot of SL (listed as redhat) and deleted the REDHAT and Boot directorys leaving only the Manjaro folder. Then with an update-grub I created a new grub.cfg file.
The command in the Arch forks like Manjaro is the following:
grub-mkconfig -o /boot/grub/grub.cfg
After the above command, Manjaro re-created the redhat folder but under its own boot screen.
and the result on the Manjaro boot screen (sorry for the oblique photo but I can not stand the big emotions)
After all the above I explored the incredible distribution. Of course, every Linux can be customized and brought to yours. So I installed Cinnamon without a problem, but I had problems with tools that I personally need. Filezilla available in the repositories of the distribution is in an earlier version, and gftp is not even available, of course you can upgrade or find it (gftp) from the official application page but the repositories of distribution (even the epel) do not contain them.
Of course you need to install the packages you need, which will take you a little while, and it will not look so practical, especially if you're used to rolling distributors.
However, the distribution faithfully follows the development of Red Hat that made over 600 changes and fixes of their own version of the Linux kernel. Most of these fixes concerned issues of high relevance to workload and high performance.
All these changes come with Scientific Linux which along with virtualization, multiple network storage protocols, load balancing, better safety of RHLE and many other enterprise features make it a very decent and secure distribution.
