[Wrf-users] WRF-NMM installation problem for 64bit RedHat Linux with PGI 7.0-2

[Guoqing Tang]

Dear list users,

Here is a problem I ran into when I tried to nstall WRF-NMM V2.2 in a  64 bit RHEL WS 4 with PGI 7.0-2 choosing Option 3 (RSL-LITE, MPICH, Allowing Nesting, No periodic LBC). The installation was always running in an infinite loop and taking up almost 4 GB of physical memory and half of 10 GB swap space. During one installation, I let it run over night. When I came back next morning, it was still trying to compile start_domain_nmm.f90 after more than 8 hourcompilation. However, it did not give any error message in the compile log file, but just simply hanged there forever. Here is the last line of compilation where complilation went into a loop:

mpif90 -c -fastsse  -w -byteswapio -Mfree  -I../dyn_em -I../dyn_nmm  -module ../main -I../external/io_netcdf -I../external/io_int -I../external/esmf_time_f90 -I../external -I../frame -I../share -I../phys -I../inc -I../chem -r4 -i4  start_domain_nmm.f90

However, when I switched to Option 2 (RSL, MPICH, Allowing nesting), compilation went through easily in less than a hour. Both WRF-NMM and WPS were properly installed, and work fine with this choice, but WRF Postprocessor compilation won't work due to lack of prepor RSL-LITE libraries and other objet files. 

My question is: is there any fix for the installation problem when using Option 3 for 64 bit Linux? I noticed on Wrf-users online and found someone posted a similar problem. However, I haven't seen a solution to it yet. Any help is greatly appreciated. 

Thanks,
