How to build the latest version of Gunrock (a popular GPU Graph analytic library) on Redhat/Centos based systems
Prerequisites:
- cmake 3.10+
- GCC 4.8+
Although building gunrock is easy on Ubuntu 18.04, it is not easy for other OSs.
In most of the RedHat rpms, cmake is not the latest. Sometimes we do not have root/admin rights to install. In such scenarios, below steps to build cmake/gunrock.
Build/Download cmake - 4 steps
1. Download cmake*.tar.gz from
https://cmake.org/download/
download either src or binary
2. Extract
3) // do either a or b
a. if src, cd to cmake directory and do make
b. if binary, do nothing
4. To verify
./cmake-3.14.7/bin/cmake --version
displays as below
cmake version 3.14.7
CMake suite maintained and supported by Kitware (kitware.com/cmake).
Build Gunrock - 6 steps
1.) Set and export CUDA Bin path to your cuda. Mine is 9.1. Note a non-default location!
CUDA_BIN_PATH=/usr/local/cuda-9.1
export CUDA_BIN_PATH
2)
git clone --recursive https://github.com/gunrock/gunrock/
cd gunrock
3)
In gunrock folder, edit
CMakeLists.txt
at the following lines as per your GPU card. Ours is Nvidia P100. So, I
have changed that corresponding flag from OFF to ON. Find your card name using
nvidia-smi command.
if (CUDA_VERSION VERSION_EQUAL "8.0" OR CUDA_VERSION VERSION_GREATER "8.0")
option(GUNROCK_GENCODE_SM60
"ON to generate code for Compute Capability 6.0 devices (e.g. Tesla P100)"
ON)
Note: This Step may not be needed due to this

4)
mkdir build && cd build
~/install/cmake-3.14.7/bin/cmake ..
we are using the cmake which we downloaded/build previously.
Note: Always make sure your build folder is empty before cmake. If you end up with
some errors due to cmake; make sure to delete all files and folders from
build before performing cmake again.
Upon success. Should display the following:

5)
make
Takes up to an hour or so as. If no error, then that's all. If you need only a specific algorithm (say SSSP), then read
A1 below.
6) To test, cd to bin inside build dir
./sssp market ../dataset/small/test_mst.mtx
...sample output..

YAY :-)
Appendix
A1) You could build only a specific algorithm by setting an appropriate flag during your cmake as said here in
advanced compilation.
e.g. Suppose if I want SSSP alone then
/cmake-3.14.7/bin/cmake -DGUNROCK_BUILD_APPLICATIONS=OFF -DGUNROCK_APP_SSSP=ON ..
//This step builds SSSP alone when you do a make.
Errors in the past that lead to the above working steps:
E1) CMake 3.10 or higher is required. You are running version 2.8.12.2
E2) CMake Error at /home/rajesh/install/cmake-3.16.1-Linux-x86_64/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
