Description
Hello,
I have trouble parallelizing my code,
This is the error I got
…
Error in unserialize(node$con) :
MultisessionFuture (doFuture2-1) failed to receive message results from cluster RichSOCKnode #1 (PID 161140 on localhost ‘localhost’). The reason reported was ‘error reading from connection’. Post-mortem diagnostic: No process exists with this PID, i.e. the localhost worker is no longer alive.
…
It seems that it has already occurred before see #474
I tried both multicore and multisession but none of them works
Can you help me to sort this out?
Thank you
Angela
