CPPG Seminars on Computation

   Location:  Visualization Display Wall Room (sometimes Theory Seminar Room)
   Time:      alternating Fridays, at 10:30 am
   Refreshments will be available.

If you are doing "neat stuff" in parallel computing, scientific visualization, graphical user interfaces, codes integration and sharing, web based computing or data sharing, or anything else of general interest and significance in the area of scientific computing, ...come share it with us. Sign up as a speaker for a Friday seminar (send email to Stephane Ethier).
