As I am putting an attempt to resolve my issues with large IO problem, I encounter new one. I was trying to build roms program with parallel_IO and in this quest, I followed the steps as shown. I get following error as mp_collect subroutine is non-existant in revion 712 it seems. CALL mp_collect (ng...

Re: Problem with large size initial files

Hi, thank you for your reply, I am running the code on 512 cpus. I have noticed in my ".err" file that is generated by MPI suggesting segmentation fault when it starts reading 3d varibale. It is related to allocating memory. I tried with various flags along with -heap_arrays, i.e. -mcmodel=large -i-...

Re: Problem with large size initial files

The computer, I am trying to run the code on, is relatively small cluster. It has 176 compute nodes with 12 processors on each compute node. the command qnodes give following information on memory and CPUs. status = state=free,netload=578004143,gres=,ncpus=12,physmem=24659208kb,availmem=49408976kb,t...

Problem with large size initial files

Hi, I am planning to run the roms for Indian Ocean region with a resolution of 1/36 degrees. With great difficulties (as matlab fails to handle filesize of netCDF file). Here are the dimensions of the file dimensions: one = 1 ; s_rho = 40 ; time = 1 ; eta_rho = 2268 ; xi_rho = 3241 ; eta_u = 2268 ; ...

Re: pyroms maybe need update

If I may advise, do not use install pyroms script. following easy steps by reading the script. 1) install bathy_smoother. this should give error with unable to find lp_slove that exist in external folder 2) go to lp_slove folder compile it for python using setup.py in lp_slove/extra/Python folder 3)...

Re: how to install pyroms on EPD

Hi, To give my 2 cents, I would suggest Anaconda python distribution (APD) is little easier for pyroms to be installed. I faced lots of problems with EPD. I don't know why but adding any new module to EPD was a big headache for me. The only problem with APD is you may need to compile netcdf4 module ...

Re: Problem with Bulk_flux

I use Pyroms to generate forcing fields that is automatically masking all fields over the land. I am still looking into how to undo this.

Problem with Bulk_flux

Hi, I was facing problem with computation of bulk fluxes over land masked region. They were generating NaNs as RH was masked out to be 0. The code IF (RH.lt.2.0_r8) THEN !RH fraction cff=cff*RH !Vapor pres (mb) Q(i)=0.62197_r8*(cff/(PairM-0.378_r8*cff)) !Spec hum (kg/kg) ELSE !RH input was actually ...

openmp, PBS and linking of netcdf library.

Hi, I am new to ROMS. I have installed ROMS and tested the model with Upwelling problem in serial mode. Now I am trying to run the same example on our cluster. I am facing a unique problem that our system administrator is unable to solve. My model compilation goes smooth with mpif90. Model also runs...
