It has 426 computing nodes and offers a total of 8,520 cores (CPU cores).<\/li>\n<li>Fat nodes island with large memory nodes, consisting of 44 Dell PowerEdge R820 servers. Each server offers 4 Intel Xeon E5-4650v2 processors and 512 GB of central memory.<\/li>\n<li>GPU nodes island with GPU accelerated nodes, consisting of 44 Dell PowerEdge R730 servers. Each server contains 2 Intel Xeon E5-2660v3 processors, 64 GB of memory and 2 NVidia K40 GPU cards.<\/li>\n<li>Phi nodes with Xeon Phi accelerated nodes consisting of 18 Dell PowerEdge R730 servers. Each server contains 2 Intel Xeon E5-2660v3 processors, 64 GB memory and 2 Intel Xeon Phi 7120P co-processors.<\/li>\n<li>Machine learning node island, consisting of 1 server, which contains 2 Intel E5-2698v4 processors, 512 GB of central memory and 8 NVIDIA V100 GPU cards.<\/li>\n<\/ul>\n<p>The theoretical computing power of the system reaches 535 teraFlops (trillions of floating point operations per second). The infrastructure includes a high-performance 2 Petabyte storage system based on the IBM Elastic Cloud, an evolution of the IBM General Parallel File System (GPFS) and an IBM\u00a0<span style=\"font-family: Arial;\">TS3500<\/span> tape library with capacity of about 6 PB.<\/p>\n<p>Regarding security, the system offers full redundancy with each server to have dual power supply, and there is an integrated UPS installation in a separate room which ensures the uninterrupted operation of the server for 15 minutes, which is enough time for closing the system safely in the event of power failure.<\/p><\/div><a class='blox_elem_button  blox_elem_button_default blox_elem_color_background blox_elem_border_ blox_elem_button_medium light  ' style='background-color:#f7941e;' href='https:\/\/www.hpc.grnet.gr\/en\/' target='_self'><i class='icon-info-circle'><\/i> HPC - High Performance Computing<\/a><\/div><div class=\"col-xs-12 col-xxs-4 col-sm-4 col-md-4 col-lg-4\"><\/div><\/div>\n\t\t\t<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":16488,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"categories":[],"tags":[],"class_list":["post-2898","page","type-page","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.2 - aioseo.com -->\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<link rel=\"canonical\" href=\"https:\/\/grnet.gr\/en\/services\/cloud-services\/hpc\/\" \/>\n\t<meta name=\"generator\" content=\"All in One SEO (AIOSEO) 5.0.2\" \/>\n\t\t<meta property=\"og:locale\" content=\"en_US\" \/>\n\t\t<meta property=\"og:site_name\" content=\"GRNET Website - GRNET\" \/>\n\t\t<meta property=\"og:type\" content=\"article\" \/>\n\t\t<meta property=\"og:title\" content=\"HPC \u2013 High Performance Computing - GRNET Website\" \/>\n\t\t<meta property=\"og:url\" content=\"https:\/\/grnet.gr\/en\/services\/cloud-services\/hpc\/\" \/>\n\t\t<meta property=\"article:published_time\" content=\"2016-04-19T07:33:09+00:00\" \/>\n\t\t<meta property=\"article:modified_time\" content=\"2024-07-18T06:43:08+00:00\" \/>\n\t\t<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n\t\t<meta name=\"twitter:title\" content=\"HPC \u2013 High Performance Computing - GRNET Website\" \/>\n\t\t<script type=\"application\/ld+json\" class=\"aioseo-schema\">\n\t\t\t{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/cloud-services\\\/hpc\\\/#breadcrumblist\",\"itemListElement\":[{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/#listItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/grnet.gr\\\/en\\\/\",\"nextItem\":{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/#listItem\",\"name\":\"Authentication and Authorization\"}},{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/#listItem\",\"position\":2,\"name\":\"Authentication and Authorization\",\"item\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/\",\"nextItem\":{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/cloud-services\\\/#listItem\",\"name\":\"Cloud Services\"},\"previousItem\":{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/#listItem\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/cloud-services\\\/#listItem\",\"position\":3,\"name\":\"Cloud Services\",\"item\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/cloud-services\\\/\",\"nextItem\":{\"@type\":\"ListItem\",\"@id\":\"https:\\\/\\\/grnet.gr\\\/en\\\/services\\\/cloud-services\\\/hpc\\\/#listItem\",\"name\":\"HPC &#8211;
