The Oak Ridge Leadership Computing Facility hosted Women in Computing's "Introduce Your Daughter to Code" for the second time on June 16, giving daughters of staff members at ORNL a chance to engage in fun programming activities and code on the Cray XK7 Titan supercomputer. This year, 25 girls ages 10 to 18 participated in the labwide event.
OLCF User Support Specialist Suzanne Parete-Koon kicked off the event with an introduction to parallel computing and Titan before ORNL intern Dasha Herrmannova and ORNL postdoctoral research associate Anne Berres walked the girls through the basics of coding in Python.
Katie Schuman, a Liane Russell Distinguished Early Career Fellow, helped the girls use a program called fractalName to generate colored fractals—repeating patterns that form shapes—based on their names and ages. The fractals were displayed on the visualization wall in the Exploratory Visualization Environment for Research in Science and Technology, or EVEREST. The girls also used Schuman's Birthday Pi code to find their birthdays in the first 100,000 digits of the number pi.
"It was really exciting to see the girls' enthusiasm and curiosity when they were coding," Katie says. "Seeing them already thinking creatively about the code is the most rewarding thing to me."
After they coded on the leadership-class machine, the girls explored the interactive Tiny Titan, which features eight Raspberry Pi processors and provides a visual simulation of a liquid in space. Tiny Titan demonstrates how additional nodes in a compute system can increase the speed of a simulation.
Katie says the feedback WiC continues to receive about the event will inform future coding activities. "Some of the parents have already said the girls wanted to download everything and keep playing with the code when they got home," she says. "There is already a desire for the next phase. We will definitely continue running the same curriculum and possibly expand it in the future."
The following staff members contributed to "Introduce Your Daughter to Code:" Berres, Harken, Herrmannova, Parete-Koon, Schuman, Megan Bradley, Kate Carter, Amy Coen, Katherine Engstrom, Megan Fielden, Shang Gao and Ashley Nguyen.
