To build openMPI with intel compiler:
4
5
<pre><code class="bash">
6
export CC=icc
7
export CXX=icpc
8
export F77=ifort
9
export F90=ifort
10
export FC=ifort
11
export LIBS="-lirc"
12
./configure
13
make -j 64  # or the number of cores you have

</code></pre>

Then to install it, you must do it as super user:
17
18
<pre><code class="bash">
19
su root   #sudo -s on ubuntu
20
make install
21
exit  #leave root session
22
</code></pre>
23
24
Once installed you need to tell the linker the library path, to do so:
25
26
<pre><code class="bash">
27
su root  #sudo -s on ubuntu
28
echo "/usr/local/lib" > /etc/ld.so.conf.d/iopenmpi.conf
29
ldconfig  #Tell the linker to update cache
30
exit  #leave root session
31
</code></pre>
