    Hello,

    I have a doubt about h_fsize and MPI jobs. In a MPI job, the h_fsize is limited by slot or limited by node?.

    I know that the s_vmen value is the limit for each slot. For example, if a sent the following job:

qsub -l num_proc=1,s_rt=10:00:00,s_vmem=2G,h_fsize=20G -pe mpi 32 job.sh

the memory limit by each slot is established to 2G, so in each node the memory limit is set to "2G * number_of_assigned_slots". What about the h_fsize limit?. Is similar to s_vmen or it is set by node?. That is, in the previous example, the limit is 20G or "20G * number_of_assigned_slots".

    Regards.
