[HTCondor-users] division of totaldisk to totalslotdisk with dynamic slots

[Thomas Hartmann <thomas.hartmann@xxxxxxxx>]

hi,
i have configures an htcondor cluster with dynamic slots. this works so 
far, however, one behavior seems strange and i have no idea why this is 
happening and how to fix it:

the dynamic "masterslot" is configure like this in the config file of 
the execution host:

SLOT_TYPE_1 = 100%
SLOT_TYPE_1_PARTITIONABLE = TRUE
NUM_SLOTS_TYPE_1 = 1
NUM_SLOTS = 1

the execution host has 144 CPUs. when i submit some jobs, new slots 
appear as expected. the strange thing is, when i look at the classads of 
this new slot, i see this:

TotalSlotDisk = 431664.0
TotalDisk = 43166420

so, in contrast to the manual, every slot gets assigned 1/100 of the 
totaldisk value, although they are supposed to be equal. the value of 
TotalSlotDisk does not depend on anything i put into the submission file 
like request_disk. it is always like this, independent of how many jobs 
are submitted and how many resources they actually request.

another strange thing happens when i configure the slot like this:

SLOT_TYPE_1 = cpu=100%,memory=100%,disk=50%

this leads to the following output when, on the idle cluster, i issue: 
condor_status -avail -autoformat Disk

21583144

this number is right in that case, because it is, as expected, 50% of 
the available disk space. however, this does not change the 
TotalSlotDisk and TotalDisk within the busy dynamic slots as soon as i 
submit jobs.

may i ask you for some help here to figure out, what i do wrong?

thanks a lot in advance,
thomas
