[SCore-users] Omni/SCASH benchmarks

[Nick Birkett]

Hi I am trying to test Omni/scash under Myrinet 2k.

Does Omni /scash support SMP nodes yet ?

I have downloaded the OpenMP Nas benchmarks for C :  NPB2.3-omp-C.tgz

and used this in the config/make.def

#---------------------------------------------------------------------------
# This is the C compiler used for OpenMP programs
#---------------------------------------------------------------------------
CC = omcc -omniconfig=scash
# This links C programs; usually the same as ${CC}
CLINK   = omcc -omniconfig=scash -lm

and make the examples like this:

make lu CLASS=A



   =========================================
   =      NAS Parallel Benchmarks 2.3      =
   =      OpenMP C Versions                =

The code crashed and exited here.

Anybody seen this problem  ?

Thanks,
