<div> </div>
<div>I don't know if this is the correct list to ask this question. I just want to understand.</div>
<div>I have a a.c (attached) software, a hello world MPI using OpenMPI.</div>
<div>This is what I've done:</div>
<div>solaris@solaris:~/mpi$ mpicc a.c</div>
<div>solaris@solaris:~/mpi$ mpirun -H localhost,<a href="mailto:solaris@192.168.0.106" target="_blank">solaris@192.168.0.<wbr>106</a> a.out</div>
<div> </div>
<div>The result:</div>
<div><span style="color:rgb(255,0,0)">librdmacm: couldn't read ABI version.<br>
librdmacm: assuming: 4<br>
CMA: unable to get RDMA device list<br>

Greetings from process 1 of 2!</span><br>
</div>
<div>The Blue Section is exatcly what I <span lang="en"><span>expected</span></span>, however the Red section <span lang="en"><span>I didn't understand. Then I did a search using keyword </span></span><span style="color:rgb(255,0,0)">librdmacm</span> and discover the <span style="color:rgb(0,100,0)"><a href="http://openfabrics.org" target="_blank">openfabrics.org</a></span> wich <span lang="en"><span>I</span> <span>did not even know</span> <span>of its existence</span></span>. Can you help me to understand this red section and if I have to fix anything in my system to learn MPI? (I'm following a book)</div>
<div> </div>
<div>My System is composed by two computers x86 running Solaris 11.3, using common router tp-link, ethernet, acttually there is not anything special in my network (I'm telling this because I see in <a href="http://openfabrics.org" target="_blank">openfabrics.org</a> a technollogy called InfiniBand), OpenMPI installed from Oracle Packages, a.out inside each computer in same folder.</div>
