Compiling LTTng for the Xeon Phi


I am currently in trying to compile LTTng for the Xeon Phi for the first time, I started by trying to compile Userspace-RCU which should support the Xeon Phi, as x86_64-linux-k1om is recognized. I am using GCC provided in the MPSS release, as I do not need vectorisation for it. I am using a CentOs 6.6 computer with mpss 3.4.2 installed on it. Intel Parallel studio 2015 is also installed.

I am currently trying :

CC=/opt/mpss/3.4.2/sysroots/x86_64-mpsssdk-linux/usr/bin/k1om-mpss-linux/k1om-mpss-linux-gcc ./configure --host=x86_64-k1om-linux

Mac OS X installer problem

So, I downloaded the latest installer image <m_fcompxe_2016.1.043.dmg>. Installed the latest Xcode (7.1.1) and also the command line developer tools. Then opened the Intel Fortran installer image and launched the installer application <>. I was logged in as Administrator, and am running OS X El Capitan 10.11.1. I have a valid product serial number for Intel® Parallel Studio XE Composer Edition for Fortran OS X*. The installer application provided a screen to select between two options: 1. Install as Administrator. 2. Install as root.

[SCIF user guide] Alignment and DMA transfers question


in the subsection 4.1 in the SCIF user guide it is written the following.

“Lower performance will likely be realized if the source and destination base addresses are not cacheline aligned but are

separated by some multiple of 64.”

This sentence confuses me. What do you mean by separated. An example would really help.

Could somebody clarify this case?

Thank you in advance,
