I am currently work on a research project which requires 
parallel technique.  I have successfully adapted an Rmpi code from the 
following website. http://math.acadiau.ca/ACMMaC/Rmpi/task_pull.R and be able to run my own code now.  



However, since I am developing my own code which involves many 
calculations, each time I had an error with my Rmpi code, I got an error
 message like the following: 

 

Error in inherits(x, "data.frame") : object 'mean_chain' not found

Calls: write.table -> is.data.frame -> inherits

Execution halted



I therefore correct the error and re-run the code, the odd thing is that
 in our cluster, the previous version of my R code is loaded and the new
 one is just ignored, so I end up with the same error message.  I tried 
to use 

#

R CMD BATCH  --no-restore /home/sph/jma/Rmpi/ext2/ext2_pull.R   to prohibit the previous version, it does not work. 



Basically, how can I clean up the cluster if I have an error in my Rmpi code?



Thank you very much and I appreciate your help!
