3.8.11 NEC SX-5

First attempts to compile CO5BOLD on neSH at the Rechenzentrum Kiel and on hwwsx5 at HLR Stuttgart:

An environment variable has to be set to F_RECLUNIT=BYTE (before execution of a program) to enable UIO to compute proper record lengths. The cross compiler (on sunsrv or crossi) is called with sxf90. Thus, the environment variable F90_COMPILER=sx90 has to be set before running the configure script.

No optimized version of CO5BOLD has been achieved yet.

Some maybe useful switches are

• sx5: generate instructions for SX-5

• C vopt: normal optimization in vector mode

• -Wf'-M noflunf -M noinv -M noinexact -M setall': suppress some exceptions

• -P openmp: parallelization with OpenMP

• -Ep: call cpp preprocessor

• -pi exp=...: inlining of a list of routines (see Sect. 3.8.2)

• -dw -float0 (no special environment variable): use internally and in files the 4Byte big_endian format

The compiler flags in the configure script are

  F90FLAGS="-C hopt -sx5 -dw -float0
  -Wf'-L nostdout -L fmtlist -L inclist -L mrgmsg -L transform -M noflunf
      -M noinv -M noinexact -M setall'
  -pi exp=rhd_shortrad_operator exp=rhd_shortrad_dtauop ${F90MODULES}
  ${F90TIME} -DMSrad_raytas=1"
