OpenMP Usage

OpenMP Installation

Env: Debian 4.0 amd64 2.6.20-krg SMP with Kerrighed 2.3.0
Step1: rider@hd05:~$ wget ​http://www.hpcc.jp/Omni/ftp/Omni/Omni-1.6.tar.gz
Step2: rider@hd05:~$ tar zxvf Omni-1.6.tar.gz
Step3: rider@hd05:~$ cd Omni-1.6
Step4: rider@hd05:~$ ./configure --prefix=/opt/openmp
Step5: rider@hd05:~$ make & make install
Step6: rider@hd05:~$ export OMPC_NUM_PROCS=16 (Kerrighed_machines: node0~node4)
Step7: rider@hd05:~$ export OMPC_BIND_PROCS=true

Directions:

-- The environment variable OMPC_NUM_PROCS specifies the number of threads to execute the program. For example, you want to use 4 threads,

setenv OMPC_NUM_PROCS 4

-- If the environment variable OMPC_NUM_PROCS is not set, check the

number of physical processors in your platform. The same number of threads are created as the number of physical processor. In Linux and Solaris platforms, the runtime system checks the number of processors. Otherwise, the current version uses a compile-time constant N_PROC_DEFALUT (currently 4) in "ompclib.h" as the number of threads.

-- If the environment variable OMP_NUM_THREADS is set and its value

is greater than the number of threads described above, the value of OMP_NUM_THREADS is used as the max number of threads.

Intel C++ Compiler Installation
