Optical circuit switches and optical transceivers developed in-hou se have produced a lightwave fabric that is reconfigurable\, low latency\, rate agnostic\, and highly available. These fabrics have provided substan tial benefits for long-lived traffic patterns in tightly-coupled machine l earning clusters. We also report results for a large-scale ML superpod wit h 4096 tensor processing unit chips that has more than one exaflop of comp uting power.\n\nSpeaker(s): Dr. Kevin Yasumura\, \n\nAgenda: \n6:30 – 7: 00 PM Registration & Networking\n\n7:00 – 7:45 PM Invited Talk\n\n7:45 – 8:00 PM Questions & Answers\n\nNortheastern University Welcome Center Space\, 75 E Santa Clara Street\, San Jose\, California\, United States\, 95113\, Virtual: https://events.vtools.ieee.org/m/450615 LOCATION:Northeastern University Welcome Center Space\, 75 E Santa Clara St reet\, San Jose\, California\, United States\, 95113\, Virtual: https://ev ents.vtools.ieee.org/m/450615 ORGANIZER:jeronimo.segovia@ieee.org SEQUENCE:7 SUMMARY:Lightwave Fabrics: At-Scale Optical Circuit Switching for Datacente r and Machine Learning Systems URL;VALUE=URI:https://events.vtools.ieee.org/m/450615 X-ALT-DESC:Description: <br /><p style="text-align: justify\;"><strong>Abst ract</strong></p>\n<p style="text-align: justify\;">We describe our experi ence developing what we believe to be the world&rsquo\;s first large-scale production deployments of lightwave fabrics used for both datacenter netw orking and machine-learning applications.&nbsp\; Optical circuit switches and optical transceivers developed in-house have produced a lightwave fabr ic that is reconfigurable\, low latency\, rate agnostic\, and highly avail able.&nbsp\; These fabrics have provided substantial benefits for long-liv ed traffic patterns in tightly-coupled machine learning clusters.&nbsp\; W e also report results for a large-scale ML superpod with 4096 tensor proce ssing unit chips that has more than one exaflop of computing power.</p><br /><br />Agenda: <br /><p data-key="32"><span data-key="33"><strong data-s late-leaf="true">6:30 &ndash\; 7:00 PM Registration &amp\; Networking</str ong></span></p>\n<p data-key="34"><span data-key="35"><strong data-slate-l eaf="true">7:00 &ndash\; 7:45 PM Invited Talk</strong></span></p>\n<p data -key="36" data-slate-fragment="JTdCJTIyb2JqZWN0JTIyJTNBJTIyZG9jdW1lbnQlMjI lMkMlMjJkYXRhJTIyJTNBJTdCJTdEJTJDJTIybm9kZXMlMjIlM0ElNUIlN0IlMjJvYmplY3QlM jIlM0ElMjJibG9jayUyMiUyQyUyMnR5cGUlMjIlM0ElMjJwYXJhZ3JhcGglMjIlMkMlMjJkYXR hJTIyJTNBJTdCJTIyY2xhc3NOYW1lJTIyJTNBbnVsbCU3RCUyQyUyMm5vZGVzJTIyJTNBJTVCJ TdCJTIyb2JqZWN0JTIyJTNBJTIydGV4dCUyMiUyQyUyMmxlYXZlcyUyMiUzQSU1QiU3QiUyMm9 iamVjdCUyMiUzQSUyMmxlYWYlMjIlMkMlMjJ0ZXh0JTIyJTNBJTIyNiUzQTMwJTIwJUUyJTgwJ TkzJTIwNiUzQTQ1JTIwUE0lMjAlMjBXZWJleCUyMFJlZ2lzdHJhdGlvbiUyMiUyQyUyMm1hcmt zJTIyJTNBJTVCJTdCJTIyb2JqZWN0JTIyJTNBJTIybWFyayUyMiUyQyUyMnR5cGUlMjIlM0ElM jJib2xkJTIyJTJDJTIyZGF0YSUyMiUzQSU3QiU3RCU3RCU1RCU3RCU1RCU3RCU1RCU3RCUyQyU 3QiUyMm9iamVjdCUyMiUzQSUyMmJsb2NrJTIyJTJDJTIydHlwZSUyMiUzQSUyMnBhcmFncmFwa CUyMiUyQyUyMmRhdGElMjIlM0ElN0IlMjJjbGFzc05hbWUlMjIlM0FudWxsJTdEJTJDJTIybm9 kZXMlMjIlM0ElNUIlN0IlMjJvYmplY3QlMjIlM0ElMjJ0ZXh0JTIyJTJDJTIybGVhdmVzJTIyJ TNBJTVCJTdCJTIyb2JqZWN0JTIyJTNBJTIybGVhZiUyMiUyQyUyMnRleHQlMjIlM0ElMjI2JTN BNDUlMjAlRTIlODAlOTMlMjA3JTNBMzAlMjBQTSUyMCUyMEludml0ZWQlMjBUYWxrJTIyJTJDJ TIybWFya3MlMjIlM0ElNUIlN0IlMjJvYmplY3QlMjIlM0ElMjJtYXJrJTIyJTJDJTIydHlwZSU yMiUzQSUyMmJvbGQlMjIlMkMlMjJkYXRhJTIyJTNBJTdCJTdEJTdEJTVEJTdEJTVEJTdEJTVEJ TdEJTJDJTdCJTIyb2JqZWN0JTIyJTNBJTIyYmxvY2slMjIlMkMlMjJ0eXBlJTIyJTNBJTIycGF yYWdyYXBoJTIyJTJDJTIyZGF0YSUyMiUzQSU3QiUyMmNsYXNzTmFtZSUyMiUzQW51bGwlN0QlM kMlMjJub2RlcyUyMiUzQSU1QiU3QiUyMm9iamVjdCUyMiUzQSUyMnRleHQlMjIlMkMlMjJsZWF 2ZXMlMjIlM0ElNUIlN0IlMjJvYmplY3QlMjIlM0ElMjJsZWFmJTIyJTJDJTIydGV4dCUyMiUzQ SUyMjclM0EzMCUyMCVFMiU4MCU5MyUyMDclM0E0NSUyMFBNJTIwJTIwUXVlc3Rpb25zJTIwJTI 2JTIwQW5zd2VycyUyMiUyQyUyMm1hcmtzJTIyJTNBJTVCJTdCJTIyb2JqZWN0JTIyJTNBJTIyb WFyayUyMiUyQyUyMnR5cGUlMjIlM0ElMjJib2xkJTIyJTJDJTIyZGF0YSUyMiUzQSU3QiU3RCU 3RCU1RCU3RCU1RCU3RCU1RCU3RCU1RCU3RA=="><span data-key="37"><strong data-sl ate-leaf="true">7:45 &ndash\; 8:00 PM Questions &amp\; Answers</strong></s pan></p> END:VEVENT END:VCALENDAR
