This proposal requests NSF support to assist students in attending the 2009 International Symposium on Code Generation and Optimization (CGO 2009). CGO provides a premier venue to bring together researchers and practitioners working on feedback directed optimization and backend compilation techniques. The symposium covers compilation for parallelism, performance, power, and security. This support will broaden participation in CGO by subsidizing the travel for participants who might not otherwise travel to attend CGO. The funds will be used solely to provide travel support for students from US universities.
