Removing the 'cluster=' clause will make it show info for all clusters.

Removing the 'format=' will make it show all fields.

2. Show share info for a specific user

sshare -A nesi00213 -u tdn27 --cluster maui --format user,GrpTRESRaw%110,GrpTRESMins


GrpTRESRaw contains the 'live' usage-data slurm stored.

GrpTRESMins constains current rule/restriction a user is under.
      User                                                                                                     GrpTRESRaw                    GrpTRESMins 
----------                                                          ----------------------------------------------------- ------------------------------ 
                              cpu=21996738,mem=38765191976,energy=0,node=274959,billing=21996738,fs/disk=0,vmem=0,pages=0                                
     tdn27                       cpu=1472782,mem=15203689887,energy=0,node=18409,billing=1472782,fs/disk=0,vmem=0,pages=0                billing=1959124


IMPORTANT:

The current way Slurm is installed/setup will have a  two week half-life.

e.g. all numbers under GrpTRESRaw will decay every 5 minutes, with a rate that would halve it in 14 days.
every 5 minute the numbers are multiplied by (1-0.000124008)

3. Set Rules for a User

Lets say will want to give tdn27 4k core hours.

the result from step2 shows that he currently has 1472782

1472782+4000*60*2=1952782

*60 is because its in minutes, instead of hours
*2 is because its hyperythreaded

sacctmgr modify user where name=tdn27 account=nesi00213 cluster=maui set GrpTRESMins=billing=1959124


This command will give the user 4k CH.

Note:
because of the decay period, this step has to be constantly updated, or user will have free usage every few days.


4. Extra Notes

Combination with Historic usage from Dash board will be more precise and less manual work ( not yet implemented)
