<HTML><BODY>New special supercomputer microprocessors (like IBM Power BQC and Fujitsu SPARC64 XIfx) have 2**N +2 cores (N=4 for 1st, N=5 for 2nd), where 2 last cores are redundant, not for computations, but only for other work w/Linux or even for replacing of failed computational core.<br><br>Current Intel Haswell E5 v3 may also have 18 = 2**4 +2 cores. Is there some sense to try POWER BQC or SPARC64 XIfx ideas (not exactly), and use only 16 Haswell cores for parallel computations ? If the answer is "yes", then how to use this way under Linux ?<br><br>Mikhail Kuzminsky, <br>Zelinsky Institute of Organic Chemistry RAS,<br>Moscow<br><br><br style="border-left:1px solid #0857A6; margin:10px; padding:0 0 0 10px;">
