Restrictions on use

Access to this software is restricted to a specific research group. Please contact its-ri-team@manchester.ac.uk for more information.

Set up procedure

To access the software you must first load one of the following modulefiles:

module load apps/binapps/answers/monk/10b_ru0_mpi     # 64bit parallel MPI version
module load apps/binapps/answers/monk/10b_ru0         # 64bit serial version

module load apps/binapps/answers/monk/10a_ru0_64bit   # 64bit parallel MPI version

module load apps/binapps/answers/monk/10a_ru0         # 32bit serial version (not recommended but works)

module load apps/binapps/answers/wims/11b_dv14_mpi # 64bit parallel MPI version
module load apps/binapps/answers/wims/11b_dv11_mpi    # 64bit parallel MPI version
module load apps/binapps/answers/wims/11b_dv11        # 64bit serial version
module load apps/binapps/answers/wims/11a_dv10_mpi    # 64bit parallel MPI version
module load apps/binapps/answers/wims/11a_dv10        # 64bit serial version
module load apps/binapps/answers/wims/10a_ru0         # 32bit serial version (not recommended but works)

VisualWorkshop

module load apps/binapps/answers/visualworkshop/4a   
qrsh -l short 
module load apps/binapps/answers/visualworkshop/3b    # 32bit version (singularity image)
VisualWorkshop

# NOT CURRENTLY AVAILABLE ON CSF3
module load apps/binapps/answers/visualworkshop/3a

Nuclear Data Libraries

Various nuclear data libraries are available in the directory given by the environment variable:

$ANSWERS_DATA

For example, to see what is available, run:

ls $ANSWERS_DATA

You can use the $ANSWERS_DATA in your jobscripts (see below for examples).

Manuals

After loading a modulefile you can access the software manuals in the installation area. Use the evince command to read PDF manuals on the CSF login node.

cd $ANSWERS_HOME/manuals
ls

# Example:
cd wims11_manual_draft1
ls
evince burnup.pdf

Running the applications

Please do not run MONK or WIMS on the login node. Jobs should be submitted to the compute nodes via batch.

The VisualWorkshop application is run from a script on the login node. This will automatically request an interactive session on a backend compute node. VisualWorkshop will only run if the qrsh interactive session can be scheduled by the system (i.e., if there is a free core available in the interactive area).

VisualWorkshop (GUI)

Load the appropriate modulefile (see above) then run the following command on the CSF login node:

# Run this on the CSF login node. It will request an interactive job.
VisualWorkshop_csf

If there is a free core on an interactive node on which to run the application the GUI will start. If all of the interactive resources are in use you will see a message:

Your "qrsh" request could not be scheduled, try again later.

Please try again later.

If you prefer to start an interactive session first, and then run VisualWorkshop please do the following:

# From the CSF login node request an interactive session
qrsh -l short

# When you have been logged in to the compute node:
module load apps/binapps/answers/visualworkshop/3b

# Now run the app interactively - this won't request a compute node - you are already on one!
VisualWorkshop_inter

Note that the interactive session will run for a maximum of 1 day.

MONK

Serial batch job submission

Make sure you have the required MONK modulefile loaded then create a batch submission script, for example:

#!/bin/bash --login
#$ -cwd             # Job will run from the current directory

# We recommend loading the modulefile in the jobscript (change to your required version)
module load apps/binapps/answers/monk/10b_ru0

monk10b.out datsets=datsets.lis

Submit the jobscript using:

qsub scriptname

where scriptname is the name of your jobscript.

Parallel batch job submission

Make sure you have the required MONK modulefile loaded then create a batch submission script, for example:

#!/bin/bash --login
#$ -cwd             # Job will run from the current directory
#$ -pe smp.pe 8     # Number of cores to use (Available 2 to 32)
                    # Note: If you were previously running multi-node jobs
                    # using orte-12-ib.pe on either CSF or Redqueen
                    # please email its-ri-team@manchester.ac.uk for help.

# We recommend loading the modulefile in the jobscript (change to your required version)
module load apps/binapps/answers/monk/10b_ru0_mpi

mpirun -n $NSLOTS monk10b_mpi.out datsets=datsets.lis

Submit the jobscript using:

qsub scriptname

where scriptname is the name of your jobscript.

WIMS

Serial batch job submission

Create a batch submission script, for example:

#!/bin/bash --login
#$ -cwd             # Job will run from the current directory

### We recommend loading the modulefile in the jobscript (change to your required version)
module load apps/binapps/answers/wims/11a_dv10

### Change this to select your required nuclear library
export LIBRARY=$ANSWERS_DATA/w10j312v1.dat

wims11a_dv10_64.out library=$LIBRARY input=./my_sim.txt output=./my_sim.out space=8000000

Submit the jobscript using:

qsub scriptname

where scriptname is the name of your jobscript.

Parallel batch job submission

Create a batch submission script, for example:

#!/bin/bash --login
#$ -cwd             # Job will run from the current directory
#$ -pe smp.pe 8     # Number of cores to use (Available 2 to 32)

### We recommend loading the modulefile in the jobscript (change to your required version)
module load apps/binapps/answers/wims/11a_dv10_mpi

### Change this to select your required nuclear library
export LIBRARY=$ANSWERS_DATA/w10j312v1.dat

### You must specify the full path to the wims executable using 
### $WIMS_HOME/wims11a_dv10_64.out otherwise your job will fail
### if it tries to run the wecco executable as part of the job.

mpirun -n $NSLOTS $WIMS_HOME/wims11a_dv10_64.out library=$LIBRARY \
          input=./my_sim.txt output=./my_sim.out space=8000000

Submit the jobscript using:

qsub scriptname

where scriptname is the name of your jobscript.
