How can I get a stack trace back from a snow node after an error occurs?
I am using the snow package (version 0.3-3) on R 2.10.1 and I'm getting errors when I use parSapply that do not occur when I use sapply. Snow is nice enough to give me the error message but it would be much more useful for me to have the kind of stack trace you can get from traceback(). So far I have tried:
options(showWarnCalls = T, showErrorCalls = T) setDefaultClusterOptions(outfile = "/dev/tty")
options(error=traceback) setDefaultClusterOptions(outfile = "/dev/tty")
without luck. I'm currently just testing with a local cluster ie:
but I will eventually be using an MPI cluster. Thanks.
