Hello,
I have been using OPEN-MPI for several years now on 8-16 CPU/Core machines. I
want to extend the usage to graphic-card devices (NVIDIA-cards). Therefore,
I use open-mpi implementation on x number of CPU´s working well (linux/ubuntu):
The CPU installation:
1) makefile look like this:
****
CC = mpic++
SDIR = ./
IMPI = /usr/lib/openmpi/include
LMPI = /usr/lib/openmpi/lib
ISCL = $(HOME)/applik-libscl/libscl/gpp
LSCL = $(HOME)/applik-libscl/libscl/gpp
IDIRS = -I. -I$(SDIR) -I$(IMPI) -I$(ISCL)
LDIRS = -L$(LMPI) -L$(LSCL)
CFLAGS = -O -Wall -c $(IDIRS)
LFLAGS = $(LDIRS) -lscl -lm
hello : hello.o
$(CC) -o hello hello.o $(LFLAGS)
hello.o : $(SDIR)/hello.cpp $(HEADERS)
$(CC) $(CFLAGS) $(SDIR)/hello.cpp
clean :
rm -f *.o core core.*
veryclean :
rm -f *.o core core.*
rm -f hello
*****
2) and I simultaneously compile and execute with the sh-file:
*****
echo "localhost cpu=24" > OpenMPIhosts
test -f hello.err && mv -f hello.err hello.err.bak
test -f hello.out && mv -f hello.out hello.out.bak
make -f makefile.mpi.OpenMPI_1.4 >hello.out 2>&1 && \
mpirun --hostfile OpenMPIhosts ${PWD}/hello >>hello.out 2>hello.err
RC=$?
case $RC in
0) exit 0 ;;
esac
exit 1;
I have now some questions:
Can this parallel program (hello) be extended by also using Graphic processors
card (i.e. Nvidia-cards) using hwloc = internal in version Open-mpi 1.7.1
(installation).
If yes:
Any changes in makefiles? Execute-files? Program-files?
Suggestions for implementations are appreciated!
The graphic card devices should be the extensions of a machine's CPUs.
