Gunrock building problem

[hgyhungry]

The gunrock-test building process is not working.

Problem:

• makefile cannot be generated due to inconsistency between the cmakelist I provide and the one pulled from the gunrock repo
• users report that running test script cause 'invalid device function' exception. It is probably due to incorrect gencode flag during the building process.

cd gunrock-test
cp -r app/spmm ./gunrock/gunrock/app/
cp -r examples/spmm ./gunrock/examples
cp CMakeList.txt ./gunrock/examples

mkdir build && cd build
cmake .. && make spmm -j8

How can I run this instruction?I'm running make spmm -j8，but command box points out make: *** No rule to make target 'spmm'. Stop. under ubuntu18.04.

It seems that 'cmake ' cannot go through, so 'make' fails. Try the following steps

git clone --recursive https://github.com/hgyuhungry/ge-spmm # this step may give error about gunlock's submodule, but it's ok to continue
cd ge-spmm/gunrock-test/gunrock
git submodule update externals/cub externals/moderngpu externals/rapidjson
mkdir build && cd build && cmake ..
make spmm

The only change is the git submodule update... line. Gunrock has one submodule external/docs which is causing trouble during recursive pulling, but we do not need it to benchmark. So you can manually ask git to pull the submodules that we need. And build .

Hope this helps.
