Am also having the same problem its so frustrating… I have to finish something soon and don’t have time to look into cuda gdb; as I don’t have computer science background.
Now the device emu doesn’t work hence I cant test my algorithm … as to why I am not getting correct results… I relied on simple printf’s in device emu till now for debugging and I was happy.
Register as a developer (just enrol in the site and get registered in 2 mins - check the cuPrintf thread - tmurray started it) and get the cuPrintf package and be happy.
really you should just learn how to use gdb. cuda-gdb is basically the same as gdb, and I can’t imagine being anywhere close to as productive as I am currently without a decent debugger.
What’s the best way to learn cuda-gdb? It comes with a 14 page PDF which is a great start… there’s a 4 page walkthrough, but I want more of those walkthrough examples to get a feeling of how to use it to attack different kinds of problems. A video would also be useful… just a live capture of a demo on some apps so you can SEE the workflow.
