Institute for Condensed Matter Physics of NAS of Ukraine. Since that time the cluster was already upgraded for several times, and due to this it remains as one of the powerful clusters in Ukraine. </p> <p>After the last upgrade in december of 2006, the cluster of ICMP was extended by 17 new nodes of dual-core 64-bits processors (Xeon 5130) and RAM of 4 Gb. Due to this the test performance of the cluster increased by <span style="font-weight: bold;">310 GFlops</span>. At the same time the theoretical peak performance of the whole cluster is estimated as <span style="font-weight: bold;">680 GFlops</span>.<br> </p> <p>In this moment the cluster of ICMP consits of two parts. One part of the cluster is built of 13 nodes based on Athlon MP 2200+ and 6 nodes based on Opteron 246 interconnected by by Gigabit Ethernet. Another part of the cluster is built of 17 nodes of Xeon 5130 interconnected by Infiniband 4x SDR. All nodes of the ICMP Cluster are dual, i.e. each of them contains two corresponding CPUs. Therefore, the ICMP cluster is composed of <b>72 CPUs</b> totally. </p> Except the PGI compillers, all computers within the ICMP cluster are running the freely available and open source operating system Linux based on <i>Red Hat 9</i> òà <span style="font-size: 12pt; font-family: "Times New Roman";" lang="UK"><span style="font-style: italic;">CentOS 4.0-4.4</span> </span><span style="font-style: italic;"></span> distributions. Also the job management system <span style="font-style: italic;">OpenPBS</span> is used to distribute the cluster resources and to control job queues. <p>Parallel capabilities are achieved through the use of <span style="font-style: italic;">MPICH</span> libraries – a portable implementation of MPI. In addition to the PGI compilers, the usual GNU compilers are avaible. </p> </div> </div></td> <td width="16"> </td> </tr> <!--DWLayoutTable--> </table></td> </tr> </table></td> </tr> <tr> <td height="31" valign="top"><table width="100%" border="0" cellpadding="0" cellspacing="0" background="images/background5.jpg"> <!--DWLayoutTable--> <tr> <td width="577" height="31"> </td> </tr> </table></td> </tr> </table></td> </tr> </table></div>
