It will now be placed in the bindir and will be populated with all the known information. Beware: one still has to manually set the CUDA lib and path as they are not available after configure (unlike the include which is). Conflicts: opal/datatype/cuda/Makefile This file was certainly not supposed to be here. There is NO valid reason to have a copy of a locally generated file in the source. Add the capability to install the generated library and other minor cleanups. Open the datatype CUDA library from a default install location. Various other minor cleanups. --- configure.ac | 4 + opal/datatype/cuda/Makefile | 40 - opal/datatype/cuda/Makefile.in | 60 + opal/datatype/cuda/opal_config.h | 2863 ----------------------------- opal/datatype/opal_datatype_gpu.c | 190 +- 5 files changed, 125 insertions(+), 3032 deletions(-) delete mode 100644 opal/datatype/cuda/Makefile create mode 100644 opal/datatype/cuda/Makefile.in delete mode 100644 opal/datatype/cuda/opal_config.h diff --git a/configure.ac b/configure.ac index f1b53d166a0..24ce9a8b7b3 100644 --- a/configure.ac +++ b/configure.ac @@ -1416,6 +1416,10 @@ m4_ifdef([project_oshmem], opal_show_subtitle "Final output" +if test "$OPAL_cuda_support" != "0"; then + AC_CONFIG_FILES([opal/datatype/cuda/Makefile]) +fi + AC_CONFIG_FILES([ Makefile diff --git a/opal/datatype/cuda/Makefile b/opal/datatype/cuda/Makefile deleted file mode 100644 index e76f160fb88..00000000000 --- a/opal/datatype/cuda/Makefile +++ /dev/null @@ -1,40 +0,0 @@ -CC = gcc -NVCC = nvcc -ARCH = ar -ARCHFLAGS = cr -RANLIB = ranlib -STLIB ?= opal_datatype_cuda.a -DYLIB ?= opal_datatype_cuda.so -CFLAGS = -g -G -O0 -EXTLIB = -L/home/wwu12/ompi/ompi-gpu/opal/datatype/.libs -ldatatype -L/usr/lib64 -lcuda -INC = - -SRC := \ - opal_datatype_cuda.cu \ - opal_datatype_pack_cuda_kernel.cu \ - opal_datatype_pack_cuda_wrapper.cu \ - opal_datatype_unpack_cuda_kernel.cu \ - opal_datatype_unpack_cuda_wrapper.cu \ - -OBJ := $(SRC:.cu=.o) - -.PHONY: all clean cleanall - -all: $(STLIB) $(DYLIB) - -$(STLIB): $(OBJ) - $(ARCH) $(ARCHFLAGS) $@ $(OBJ) - $(RANLIB) $@ - -$(DYLIB): $(OBJ) - $(NVCC) $(CFLAGS) $(EXTLIB) -shared --compiler-options '-fPIC' -o $(DYLIB) $(OBJ) - -%.o: %.cu - $(NVCC) $(CFLAGS) $(EXTLIB) -gencode arch=compute_35,code=sm_35 $(INC) -c --compiler-options '-fPIC' $< -o $@ - -clean: - rm -f *.o - -cleanall: clean - rm -f $(STLIB) - rm -f $(DYLIB) diff --git a/opal/datatype/cuda/Makefile.in b/opal/datatype/cuda/Makefile.in new file mode 100644 index 00000000000..f00ca4e030c --- /dev/null +++ b/opal/datatype/cuda/Makefile.in @@ -0,0 +1,60 @@ +@SET_MAKE@ + +AM_CPPFLAGS = @common_cuda_CPPFLAGS@ +srcdir = @srcdir@ +top_builddir = @top_builddir@ +top_srcdir = @top_srcdir@ +VPATH = @srcdir@ + +NVCC = nvcc +ARCH = @AR@ +ARCHFLAGS = cr +STLIB ?= opal_datatype_cuda.a +DYLIB ?= opal_datatype_cuda.so +EXTLIB = -L$(top_builddir)/opal/datatype/.libs -ldatatype -L$(top_builddir)/opal/.libs -lopen-pal -L/usr/local/cuda/lib -lcuda +subdir = opal/datatype/cuda + +CC = nvcc +CFLAGS = -I$(top_builddir)/opal/include -I$(top_srcdir)/opal/include -gencode arch=compute_35,code=sm_35 --compiler-options '-fPIC @CFLAGS@' +LDFLAGS = -shared --compiler-options '-fPIC @LDFLAGS@' + +SRC := \ + opal_datatype_cuda.cu \ + opal_datatype_pack_cuda_kernel.cu \ + opal_datatype_pack_cuda_wrapper.cu \ + opal_datatype_unpack_cuda_kernel.cu \ + opal_datatype_unpack_cuda_wrapper.cu + +OBJ := $(SRC:.cu=.o) + +.PHONY: all clean cleanall + +all: Makefile $(STLIB) $(DYLIB) + +Makefile: $(srcdir)/Makefile.in $(top_builddir)/config.status + @case '$?' in \ + *config.status*) \ + cd $(top_builddir) && $(MAKE) $(AM_MAKEFLAGS) am--refresh;; \ + *) \ + echo ' cd $(top_builddir) && $(SHELL) ./config.status $(subdir)/$@ $(am__depfiles_maybe)'; \ + cd $(top_builddir) && $(SHELL) ./config.status $(subdir)/$@ $(am__depfiles_maybe);; \ + esac; + +$(STLIB): $(OBJ) + $(ARCH) $(ARCHFLAGS) $@ $(OBJ) + @RANLIB@ $@ + +$(DYLIB): $(OBJ) + $(NVCC) $(LDFLAGS) $(EXTLIB) -o $(DYLIB) $(OBJ) + +%.o: %.cu + $(NVCC) $(CFLAGS) $(EXTLIB) $(INC) -c $< -o $@ + +install: $(DYLIB) + cp -f $(DYLIB) @OMPI_WRAPPER_LIBDIR@/ + +clean: + rm -f $(OBJ) + +cleanall: clean + rm -f $(STLIB) $(DYLIB) diff --git a/opal/datatype/cuda/opal_config.h b/opal/datatype/cuda/opal_config.h deleted file mode 100644 index d23f071a86a..00000000000 --- a/opal/datatype/cuda/opal_config.h +++ /dev/null @@ -1,2863 +0,0 @@ -/* opal/include/opal_config.h.

However, cudaMallocHost does not work with realloc, so use malloc instead make sure check pointer is not NULL before free it rewrite non cached iov, make it unified with cached iov checkpoint, rewrite non-cached version fix for non cached iov fix the non cached iov, set position should be put at first move ddt iov to cuda iov into a function merge iov cached and non-cached for non cached iov, if there is no enough cuda iov space, break --- opal/datatype/cuda/opal_datatype_cuda.cu | 369 +++++++++++++++++- opal/datatype/cuda/opal_datatype_cuda.cuh | 46 ++- .../cuda/opal_datatype_cuda_internal.cuh | 41 +- .../cuda/opal_datatype_pack_cuda_kernel.cu | 86 +++- .../cuda/opal_datatype_pack_cuda_wrapper.cu | 362 ++++++++++++++--- .../cuda/opal_datatype_unpack_cuda_kernel.cu | 103 ++++- .../cuda/opal_datatype_unpack_cuda_wrapper.cu | 333 +++++++++++++++- opal/datatype/opal_convertor.h | 18 +- opal/datatype/opal_convertor_raw.c | 27 +- opal/datatype/opal_datatype.h | 10 +- opal/datatype/opal_datatype_create.c | 26 +- opal/datatype/opal_datatype_cuda.c | 39 +- opal/datatype/opal_datatype_cuda.h | 7 +- opal/datatype/opal_datatype_destroy.c | 15 +- opal/datatype/opal_datatype_optimize.c | 7 - opal/datatype/opal_datatype_pack.c | 2 +- opal/datatype/opal_datatype_unpack.c | 2 +- test/datatype/ddt_benchmark.c | 35 +- test/datatype/ddt_lib.h | 4 +- 19 files changed, 1344 insertions(+), 188 deletions(-) diff --git a/opal/datatype/cuda/opal_datatype_cuda.cu b/opal/datatype/cuda/opal_datatype_cuda.cu index 6a6e06ff28d..2c76a327197 100644 --- a/opal/datatype/cuda/opal_datatype_cuda.cu +++ b/opal/datatype/cuda/opal_datatype_cuda.cu @@ -15,6 +15,7 @@ ddt_cuda_device_t *cuda_devices;
