13. CS 524 - High-Performance Computing (Au 2005-2006) - Asim Karim @ LUMS13 Other Stuff How to contact me?  Office hours: 11.40 to 13.00 TR (office: 429)  E-mail: akarim@lums.edu.pkakarim@lums.edu.pk  Please see me during my office hours only. If you need to see me at another time, send me an e-mail for an appointment. Philosophy  Knowledge cannot be taught; it is learned.  Be excited. That is the best way to learn. I cannot teach everything in class. Develop an inquisitive mind, ask questions, and go beyond what is required.  I don’t believe in strict grading. But… there has to be a way of rewarding performance.
