CGO stands for a rather long "2005 International Symposium on Code Generation and Optimization with special emphasis on feedback-directed and runtime optimization". The deadline for submitting papers is September 13, 2004.
As usually, CGO is co-located with the Managed Runtime Environments workshop. The deadline for submitting papers to MRE is January 7, 2005.
CGO and MRE will take place in March 2005 in San Jose, California.
