&gt;<br>
&gt;<br>
&gt;<br>
&gt; Hi Rayson,<br>
&gt;<br>
&gt;<br>
&gt;<br>
&gt; I noticed that StarCluster didn´t allocate a placement group for C3 instances and did it by myself in the code.<br>
&gt;<br>
&gt; But this was not helpfull since C3 instances uses high throughput insted of the 10 giga network.<br>
&gt;<br>
&gt; In my tests, using C3 or CC2 in a cluster config where MPI is required will be equal to same processing time.<br>
&gt;<br>
&gt; Hope that AWS put them on 10 Giga net in the near future.<br>

&gt; &gt; Hi everyone,<br>
&gt; &gt;<br>
&gt; &gt; I attended AWS Re:Invent this year and liked a lot. Right place to go.<br>
&gt; &gt; AWS announced there the new C3 family of HPC instances.<br>
&gt; &gt; I´m anxious to test them in my models but I understand that StarCluster must<br>
&gt; &gt; take aware of them in the code.<br>
&gt; &gt; So when will be the C3s available?<br>
