building CCSM3 on Linux

[wuxq]

Hi,

I am trying to build CCSM3 on our local Linux Cluster. When I run
'ccsm3_ctl.generic_linux.build', the cpl, ice and lnd components are compiling smoothly. But the ocn compiling is so slow and basically hangs there for several hours. Here is the line in the ocn.buildexe file

mpif90 -I. -I/usr/local/netcdf/include -I/tera3/wuxq/CCSM3/ccsm3_ctl/lib/include -I/usr/local/mpi/include -I/tera3/wuxq/CCSM3/ccsm3_ctl/ocn/obj/source -c -r8 -i4 -Kieee -Mrecursive -Mdalign -Mextend -byteswapio -DLINUX -DPGF90 -DNO_SHR_VMATH -DLINUX -DPOSIX -Dimpvmix -Dcoupled -DNPROC_X=4 -DNPROC_Y=6 /tera3/wuxq/CCSM3/ccsm3_ctl
/ocn/obj/source/baroclinic.F

Any suggestion for solving this problem?

Thank you

I believe that you are using a version of the PGI compiler that is not supported or validated on any Linux cluster. Per the documentation available from the ccsm web and this bulletin board, the only PGI compilers that have been validated are 5.1-3 and 5.1-6. Version 5.2 and early 6.x versions are also known to be a problem. Work with 6.0-5 is underway but there is no committed completion date. Note that ALL CCSM Linux cluster validations to date have been Xeon clusters with Myrinet. Work on ethernet and InfiniBand are underway but at this point are not a high priority.
