use MPI for server and shhh.flows


Could you please tell me if it is possible run mothur with MPI option in a server (not cluster)? I am trying to run shhh.flows using your advice, use mpirun -np x “#shhh.flows(…)”. If this is possible, could you help me to interpret this error?

-bash: runmpi: command not found
sgaraycochea@INIA-LB-SLES11SP2:~/Metagenomica_suelos/Analisis_mothur> ./runmpi mothur_MPI
-bash: ./runmpi: No such file or directory
sgaraycochea@INIA-LB-SLES11SP2:~/Metagenomica_suelos/Analisis_mothur> ./mothur_MPI

Thank you very much

It looks like the error message is just a typo,

Here’s the basic format for mpirun:
mpirun -np

sgaraycochea@INIA-LB-SLES11SP2:~/Metagenomica_suelos/Analisis_mothur> ./runmpi mothur_MPI

As a side note, we have found our MPI version to slower than the NON-MPI version, and will be removing the source from mothur for our next version. You might try the regular version and use multiple processors,
