Parallel mode failed

[wkqian06]

Hi there, thanks for this amazing algorithm!
I tried to run parallel mode on cluster. Although there was no error apparedin the codes, I found that the program was always waiting for the response, resulting in wall time up to the time limit and cpu time to only 1 sec. However, everything goes well if i turn off parallel mode both with cpu and gpu. How can I get over this issue? I really need to use parallel mode to save the running time.

Update: I tried the codes in my local environment, and it works smoothly.
