In particular, the course will start from the part dedicated to computer architectures, and will place greater emphasis on interconnection topologies for HPC and PD systems and the related communication problems. *Quantum computing* will be included as a new topic, with particular regard to quantum arithmetic circuits, in order to compare the classical solutions (which I will describe) with those currently being studied for quantum computers. Theses will be proposed on the topics of this first part of the course. In the second part of the course, the remaining topics will be treated (in previous years they were treated in the first period of the course): sparse matrices, errors, linear systems, eigenvalues and eigenvectors, molecular dynamics. Depending on how the course will proceed, it is possible that some of these latter topics are only mentioned or completely skipped. *Important information* * The course will start regularly on *Wednesday, 23 February 2022*. * For in-person attendance, you should *book an attendance spot through Prodigit*, filling the form at the link: https://prodigit.uniroma1.it/ * To get information on the lessons in streaming, access the course material and receive notices, you must *register on Classroom* for the *imcilwm* course using your Sapienza email address (surname.matricola@studenti.uniroma1.it). * Lessons are scheduled for: * *Wednesday* (11:00 am - 13.00 am) * *Friday* (10:00 am - 13.00 am) * in *Room T1*, Palazzina E (Building E) Regina Elena <!-- <font color="#FF642E"> * *Due to an unforeseen commitment, tomorrow's lesson - 23rd February - will take place remotely.* <font color="#3F467A"> * You can find the link, on *Classroom* by registering for the *imcilwm* course using your Sapienza email address. ------------------------ * The first meeting of the Intensive Computation course will be on *Wednesday, 24 February 2021* * For in-person attendance, you should book an attendance spot through Prodigit, filling the form at the link: https://prodigit.uniroma1.it/ * To get information on the lessons in streaming, access the course material and receive notices, you must register on *Classroom* for the *w5ftylh* course using your Sapienza email address (surname.matricola@studenti.uniroma1.it). * Last two lectures will be: * Monday 18 May 2020 - Performance evaluation * Thursday 27 May 2020 - Final discussion on Homeworks - Students will present their solutions of homework 3, 4 and 5. * *Monday's lectures will start at 10:15.* * *Link to lectures is: https://meet.google.com/kpb-xnqv-wgk* * *22 March 2020* I created a personal folder for each student for delivering homeworks, in the Google Drive folder of Classroom.
