Scheduling GPU resources in the Grid

Tweaks and applied configuration

CREAM CE

1. Added to BLAHP script /usr/libexec/sge_local_submit_attributes.sh:

(..)
if [ -n $gpu ]; then
    echo "#$ -l gpu=${gpu}"
fi
(..)

Scheduler

1. Complex value 'gpu':

   •     #name               shortcut     type        relop requestable consumable default  urgency  
         #-------------------------------------------------------------------------------------------
         (..)
         gpu                 gpu          INT         <=    YES         YES        0        0
         (..)

2. Host(s) complexes:

   •     hostname              tesla.ifca.es
         load_scaling          NONE
         complex_values        gpu=4,mem_free=24G,virtual_free=24G
         user_lists            NONE
         xuser_lists           NONE
         projects              NONE
         xprojects             NONE
         usage_scaling         NONE
         report_variables      NONE

3. Load sensor:
