Default Fluent under SGE

Hello to everybody.

At the moment I am trying to run Fluent6.3.26 in a computational cluster under SGE (the system is Linux and the architecture is lnamd64). For this purpose I developed a script and I am able to submit jobs for the SGE queues. The problem is that even though SGE accepts the jobs, it doesn't attribute them any resources (memory) so the Fluent is completely loaded but than it stops and in the output file appears the following:

Can“t create thread 0. Cannot allocate memory.

Please if anyone knows anything about this, just drop your ideas I will appreciate any help you give. Many thanks in advance!

Joćo

PS: I am sending here my script (maybe the error is not from SGE but mine):

#! /bin/bash #$ -S /bin/bash #$ -N chip2 #$ -cwd #$ -j y #$ -r y # /bin/echo Running on host 'hostname' /bin/echo In directory: 'pwd' #$ -m be #$ -M joao.fernandes@dq.fct.unl.pt # export FLUENT_ARCH=lnamd64 # export FLUENT_INC=/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc export LM_LICENSE_FILE=/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc/license/license.dat export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc/fluent6.3.26/lib # export PATH=$PATH:/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc/bin # /bin/echo "Got $NSLOTS processors." /bin/echo "Machines:" # fluent -r6.3.26 3ddp -path/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc/fluent6.3.26/bin -sge -g -i /home/jfernandes/scripts/script2_chip.jou

If you want to run a 4-way job and on a sge queue "que-a" and sge parallel evironment "pe-a", you may run with the following command in a command console:

/home/pmota_soft/Ansys/Fluent.Inc/Fluent.Inc/fluent6.3.26/bin/fluent 3ddp -sge -sgeq que-a -sgepe pe-a 4 -g -i /home/jfernandes/scripts/script2_chip.jou

If you don't know what is sge queue or sge parallel evironment, check with your admin.
