j `nproc`Īfter these steps, driver and CM runtime are installed in the system: git clone media-driver git clone mkdir build & cd build cmake. Ģ.2 Build and install Intel(R) Media Driver for VA-API Media driver also can be built using cmake. autogen.sh -with-drivers-path=/opt/intel/mediasdk/lib64/ -prefix=/usr -libdir=/usr/lib64 make -j8 sudo make install cd.
Recommended compiler options for Debugging For this reason, when compiling on the head node for the fat/huge nodes, one should add "-xAVX" option AFTER the "-fast" option. Thus when compiling on the head node with "-fast" compiler option, the AVX2 instructions will be generated which are not supported on the fat and huge nodes. On the regular compute nodes AVX2 is supported, but on the special nodes only AVX is supported. One of the differences is the level of the supported Instruction Set Extensions. While the head node and all regular compute nodes in the cluster have Intel(R) Xeon(R) CPU E5-2640 v3 processors, the fat and huge nodes have Intel(R) Xeon(R) v2 processors. For example, mpiifort -fast -msse3 program1.f90 program2.f90 program3.f90Ĭompiling for the fat and huge compute nodes

To get the full benefit of this optimization, you must compile all program files at the same time. The -ipo option turns on inter-procedural optimization.
The -xHost compiler option tells the compiler to generate instructions for the highest instruction set available on the compilation host processor.
This option in its turn sets the following options: -ipo, -O3, -no-prec-div, -static, -fp-model fast=2, and -xHost However, the use of the following compiler option will usually provide better performance of your program. The default compiler options include such optimizations as -O2, -m64, -msse2. Recommended compiler options for High Performance Detailed information about these compilers can be found by issuing 'man icc' and 'man ifort'. Use of the Intel Fortran, C, and C++ compilers (icc, icpc, ifort) is recommended for all applications.
