Does someone know what does the error code 1 mean?
From pssh I found:
1: at least one remote command returned a non-0 value (but all commands ran)
But since the pssh call runs my program only I cannot make an interpretation based on this.
Found it using the suggestion of Andreas Prell (http://communities.intel.com/message/119923#119923); redirecting the std_error to std_out.
Error code 1 was caused by an exit(1) call..
