I can start an opencl session (one master, two remotes). I can ssh into the remote computers, enter into the john/run directory and see the session log and .rec files.
Keep in mind that the only trouble I'm having is restoring a session! My master node is only producing one .rec file.

cd /home/tony/bleeding-jumbocl/run/
./john - -form:wpapsk-opencl -dev=cpu --wordlist=rockyou.txt --rules jtr.hccap
If I ssh into the remote computers and enter the above command lines, I'll get that segment fault.
If I enter this command line instead, (without the -opencl) everything runs just fine.
./john - -form:wpapsk -dev=cpu --wordlist=rockyou.txt --rules jtr.hccap
Does that indicate an opencl problem??

An opencl problem??
