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 ${CC}
CLINK = omcc -omniconfig=scash -lm
and make the examples like this:
make lu CLASS=A
=========================================
= NAS Parallel Benchmarks 2.3 =
= OpenMP C Versions =
=========================================
cd LU; make CLASS=A
make[1]: Entering directory `/home/nrcb/benchmarks/NPB2.3-omp-C/LU'
make[2]: Entering directory `/home/nrcb/benchmarks/NPB2.3-omp-C/sys'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/home/nrcb/benchmarks/NPB2.3-omp-C/sys'
../sys/setparams lu A
omcc -omniconfig=scash -c -I../common -O3 lu.c
Compiling 'lu.c'...
omcc -omniconfig=scash -lm -o ../bin/lu.A lu.o ../common/c_print_results.o
../common/c_timers.o ../common/c_wtime.o
make[1]: Leaving directory `/home/nrcb/benchmarks/NPB2.3-omp-C/LU'
[nrcb @ cserver NPB2.3-omp-C]$ cd bin/
[nrcb @ cserver bin]$ scrun -nodes=2x1 ./lu.A
SCore-D 5.0.0 connected (jid=10).
<0:0> SCORE: 2 nodes (2x1) ready.
fatal(id=0):_ompsm_scash_fatal: shared arg stack overflow
NAS Parallel Benchmarks 2.3 OpenMP C version - LU Benchmark
Size: 64x 64x 64
Iterations: 250
The code crashed and exited here.
Anybody seen this problem ?
Thanks,
Nick
