Date: Wed, 16 Oct 2002 07:55:40 -0700 (PDT) From: To: cs575@rohan.sdsu.edu Subject: Second Computational Report2 Wednesday 16Oct02 lecture in BAM256 will cover Chapter 7 Eliminating Clutter I would also like to clarify any questions you may have on your current computational experiment. Kris Stewart stewart@rohan.sdsu.edu BAM223 Office Hours MW 1-2:30 -------------------------------------------------------- Monday 14Oct02 lecture introduced: http://www.stewart.cs.sdsu.edu/cs575/assignments/diffusion_profile_report2.html Wednesday (9Oct02) Lecture presented the background to characterize the computer solution of the Diffusion Model Sample codes are available now 1.mkdir diffusion 2.cd diffusion 3.cp ~stewart/cs575/fall02/diffusion/* . (do not forget the final "dot".) f90 -o fdiff f_diffusion.f -xlic_lib=sunperf f90 -o fdiff-sunperf f_diffusion.f sgeco.f sgesl.f blas.f cc -o cdiff c_diffusion.f -xlic_lib=sunperf Second Report (due Oct. 30), what to discover from your code. At appropriate locations in the source code, add calls to the system timer dtime. Optionally, explore the use of the C-based sytem timer gethrtime Gather data to compare the run-time performance of using the source code from Linpack, sgeco.f, sgesl.f, and blas.f with the Sun Performance Library, as linked above. Write your report, assign2.html, as both a web-page in your class account and a hardcopy print out, due in class on 30 October 02. Send email notice to stewart@rohan.sdsu.edu when the web-page is ready to be viewed. Recall, your code needs to produce data to support conclusions in your report.
