Is it true that one processor is dedicated to graphics on the multiprocessor IRIS machines ? The speedups we got for some parallel programs on a 4 processor machine suggest that. Please reply directly to me. Thanks. -Praveen Kankariya kankaria-praveen@CS.Yale.EDU

Any of them can send graphics down the pipe. However, only one processor *per process* can send graphics to the pipe. Only the original thread owns the graphics context. This is probably the cause of the results you are getting. thant
