Memory problem – in #9: CCLM

in #9: CCLM

<p> Dear Cemre, </p> <p> Memory usage of the 0.44 deg <span class="caps"> CCLM </span> job should be &lt; 2 GB. So its a serious problem. <br/> Probably the memory consumption increases in each timeloop. Maybe you can proof this with an interactive job submission (without sbatch) with 2 cpus or so. Don’t forget to give the numbers of cores in the mpirun call in that case. Montitor memory use with “top”. </p> <p> I will try to reproduce that behaviour with your configuration on the <span class="caps"> DKRZ </span> machine next week. May you could try the intel compiler if its available on your system. </p> <p> In general, for long-term simulations its better to use the chain-mode (http://redc.clm-community.eu/projects/cclm-sp/wiki/SUBCHAIN). </p> <p> Best regards, <br/> Markus </p>

Dear Cemre,

Memory usage of the 0.44 deg CCLM job should be < 2 GB. So its a serious problem.
Probably the memory consumption increases in each timeloop. Maybe you can proof this with an interactive job submission (without sbatch) with 2 cpus or so. Don’t forget to give the numbers of cores in the mpirun call in that case. Montitor memory use with “top”.

I will try to reproduce that behaviour with your configuration on the DKRZ machine next week. May you could try the intel compiler if its available on your system.

In general, for long-term simulations its better to use the chain-mode (http://redc.clm-community.eu/projects/cclm-sp/wiki/SUBCHAIN).
