An email I got through the SIAM mailing list :
Graduate and undergraduate students from all disciplines who are interested in using parallel computers efficiently and productively are invited to register for a FREE online course sponsored by the Extreme Science and Engineering Discovery Environment (XSEDE / xsede.org
The online course is an adaptation of the class Applications of Parallel Computers taught by professor Jim Demmel at U.C. Berkeley in Spring 2012. Lecture materials, quizzes, and programming exercises will be rolled out weekly from Feb. 14 to May 2. For more information on the topics covered in the course, seehttps://www.cac.cornell.edu/VW/APC/
As a prerequisite, students should have some programming experience in C or similar language. Enrollment is limited to the first 300 students and registration will close Feb. 13. To enroll, first visit https://portal.xsede.org/ to create an XSEDE portal account; then visit https://portal.xsede.org/course-calendar to register for the Applications of Parallel Computers course. Registered students will receive accounts to access XSEDE computing resources and consulting help. Those who successfully complete all quizzes and programming assignments will receive an XSEDE certificate of completion.
