they announced they are discontinue Phi https://www.extremetech.com/extreme/290963-intel-quietly-kills-off-xeon-phi ... but latest production server XEON announced last month have up to 56 cores per socket and up to eight sockets. from recent post http://www.garlic.com/~lynn/2019c.html#9 Most recent announce (last month) 56-core (processors) Platinum 9200 https://www.anandtech.com/show/14182/hands-on-with-the-56core-xeon-platinum-9200-cpu-intels-biggest-cpu-package-ever</a> https://www.servethehome.com/intel-xeon-platinum-9200-formerly-cascade-lake-ap-launched/</a> https://www.storagereview.com/intel_releases_second_generation_intel_xeon_scalable_cpus</a> https://www.hpcwire.com/2019/04/02/intel-launches-second-gen-scalable-xeons-with-up-to-56-cores/</a> "We are delivering 8-core Xeons all the way up to 56-core, the highest core count we've ever delivered on Xeon," said Shenoy. "We are delivering support for 1- 2- 4- and 8-socket glueless support for Xeon." ... snip ... aka eight socket, 56/socket, max 448 cores-processors sharing same memory providing large number of TIPS (1000s BIPS) computation power in single system. IBM sold off its (intel) server business about the time the server chip makers started saying that they are shipping over half their chips directly to the big cloud megadatacenters ... for going on two decades, the big cloud megadatacenters claim that they assemble their own servers at 1/3rd the cost of brand name servers (aka cloud operators view dataprocessing as a cost rather than profit). big cloud megadatacenters have so radically reduced their server system cost to a point that power & cooling have become major cost ... and they are focusing on total costs, including electricity/cooling cost per computation ... even getting special chip versions that improve computation electricity/cooling costs. However, the highest performance server chips can double the power reqirements for less than twice than the computation throughput. a big cloud megadatacenter will have over half million blade systems with millions of processors, being operated by 80-120 people (enormous automation) ... doubling the number of systems (for total computational power), can easily be net financial win, for optimal computation per power&cooling (and large cloud operations have several such megadatacenters around the world). -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
