Addapting CMakeLists to run with openACC

caap1 · April 6, 2018, 1:42pm

Hello,

I’m trying to use OpenACC to parallelize a SLAM system. Although i’m having some trouble adapting my makefile or my CMakeLists.txt (I really dont know which should i change).

Until know i’ve only been able to compile a small program to use openACC, following the tutorials of your channel in youtube: https://www.youtube.com/channel/UCOTuufWhV-HTIje7e9jjFQQ

For a simple file i know that i only need to have something like this on the makefile:

choose:
	@echo make c++ or make fortran or make both

CPP=pgc++
FC=pgfortran
TIMER=/usr/bin/time
OPT=
NOPT=-fast -Minfo=opt $(OPT)
ARGS=1000

c++: jsolvec.exe
	$(TIMER) ./jsolvec.exe $(ARGS)
jsolvec.exe: jsolvec.cpp
	$(CPP) -o $@ $< $(NOPT)

fortran: jsolvef.exe
	$(TIMER) ./jsolvef.exe $(STEPS)
jsolvef.exe: jsolvef.F90
	$(FC) -o $@ $< $(NOPT)

both: c++ fortran

clean:
	rm -f *.o *.exe *.s *.mod a.out

An to compile i only need to do: “make c++ OPT=”-ta:tesla:cc50 -Minfo=accel".
But, slam uses a lot of files and has giant makefiles and cmake files. My CMakeLists.txt, which i think is the one i should make the changes looks like this:

SET(PROJECT_NAME DSO)

PROJECT(${PROJECT_NAME})
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

Note that i already added the following line: “SET(CMAKE_C_COMPILER /opt/pgi/linux86-64/17.10/bin/pgc)” as a first attempt to compile with pgc. And it compiled without errors, so i think there’s no problem there. I’ve also tried to change line 30 for somthing like this:

${SSE_FLAGS} -O3 -g -std=c++0x -march=native  -ta:tesla:cc50 -Minfo=accel

This however generates errors because the compiler doesn’t know what “ta” and “Minfo” means.

Any advice on which direction should i take in order to accomplish this?

Hi caap,

I’m not an expert with CMake so may be of limited help. Though, there are a few things I see.

SET(CMAKE_C_COMPILER /opt/pgi/linux86-64/17.10/bin/pgc)

“pgc” is our back-end compiler and shouldn’t be called directly. Please use “pgcc”.

This however generates errors because the compiler doesn’t know what “ta” and “Minfo” means.

Given you also have “-march=native”, which is a GCC flag, I’m guessing you’re using GCC. I’m not sure if it’s due to the “pgc” typo or if you haven’t set the C compiler correctly.

Note that we did have an intern here last summer that work with Kitware to add OpenACC support to cmake. So more recent versions will have this support.

Detect OpenACC support by the compiler.

This module can be used to detect OpenACC support in a compiler.
If the compiler supports OpenACC, the flags required to compile with
OpenACC support are returned in variables for the different languages.
Currently, only NVHPC, PGI, GNU and Cray compilers are supported.

I changed the path, and instead of using pgcc i used pgc++ and it already recognizes -ta and Minfo flags. Aren’t these flags suppose to work on pgcc as well?

But now, i do get error becouse of the “-march=native” flag, which, as you said, is a GCC flag, and pgcc doesn’t recognize it. If i try to compile without it e get multiple code errors.

Yes, pgcc recognizes these options.

But now, i do get error becouse of the "-march=native" flag, which, as you said, is a GCC flag, and pgcc doesn't recognize it. If i try to compile without it e get multiple code errors.

The errors are probably something else unrelated to “-march=native”. What are the errors?

If i compile for pgcc and with: “set(CMAKE_C_FLAGS
“${SSE_FLAGS} -O3 -g -std=c++0x -march=native -ta=tesla:cc50 -Minfo=accel”)” i get errors like:

/usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

i change the flag -std=c++0x to -std=c++11 but still get the same errors

caap1 · April 7, 2018, 7:03pm

So, i managed to compile without errors, doing something like this:

SET(CMAKE_C_COMPILER /opt/pgi/linux86-64/17.10/bin/pgcc)
#SET(CMAKE_CXX_COMPILER /opt/pgi/linux86-64/17.10/bin/pgc++)

# flags
add_definitions("-DENABLE_SSE")
set(CMAKE_CXX_FLAGS
   "${SSE_FLAGS} -O3 -g -std=c++0x -march=native -ta=tesla:cc50 -Minfo=accel"
#   "${SSE_FLAGS} -O3 -g -std=c++0x -fno-omit-frame-pointer"
)

set(CMAKE_C_FLAGS
   "${SSE_FLAGS} -ta=tesla:cc50 -Minfo=accel"
)

Although, i don’t think the flags are being used, i get no information taht Minfo is suppose to give, and i added a pragma in the code just to see if it recognizes the language, and it does, i compile without errors, although the pragma isn’t being performed, or at least i get no evidences of that.

I think i have to uncomment the line where i tell the compiler to use pgc++, but if i do that i get an error because pgc++ doens’t know what “-march=native” because it is a gcc flag. And i can’t simply erase that flag

caap1 · April 9, 2018, 2:44pm

I am sure that i’m compiling with pgc, when calling cmake e get the following messages:

-- The C compiler identification is PGI 17.10.0
-- The CXX compiler identification is PGI 17.10.0
-- Check for working C compiler: /opt/pgi/linux86-64/17.10/bin/pgcc

-- Check for working CXX compiler: /opt/pgi/linux86-64/17.10/bin/pgc++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done

But, when i compile i get error messages in simple things like ‘;’ :

"/home/cesar/Documents/dso/thirdparty/Sophus/sophus/so3.hpp", line 801:

And i checked that this behavior is due to pgc++, if i compile with pgcc and c++ it compiles fine, but the flags doesn’t work. Compiling with pgcc and pgc++ i get those errors.

Any idea why is pgc++ generating this errors?

brentl · April 9, 2018, 9:05pm

Where does SSE2NEON.h come from?

caap1 · April 17, 2018, 5:58pm

Well, from what i’m seeing, which is weird, that file never existed, but compiling with gcc that is ignored… But now that i forced and copied those files to the project i get this erros:

Oh i see now, because in the files i have:

#include "SSE2NEON.h"
#endif

But i dont know why with gcc that variables are defined and with pgcc they are not
