NPB in HermitCore

[bguala]

Hello

I need run the NAS parallel benchmarks (NPB) in HermitCore. Is possible this?.
NPBs are implement in Fortran, the build process require run a makefile, called make.def, this file contains compilation params.
make.def generates an executable based in classes of complexity (S, A, W). Exists three classes of benchmark: BT, SP and LU, they solves diferential ecuations systems. When I run the command "make benchmark class" with the class BT, for example, it generates an executable named BT-MZ.S.x. This executable, can it run in HermitCore?. Can it build with the build process of HermitCore?.
Is there some way for solve this problem?

I already test NPB with an older version of HermitCore and it works! In make.def you have to set F77 to x86_64-hermit-gfortran and CC to x86_64-hermit-gcc. The other flags are similar to the gcc configuration, if you want to compile NPB on Linux. Please inform me, if you have any problems to build NPB.

I can't build the NPBs in HermitCore.

1) First Configuration

a) I copied the directory NPB3.3.1-MZ in libhermit/usr. NPB3.3.1-MZ has the follow structure:

NPB3.3.1-MZ-MPI
NPB3.3.1-MZ-OMP = this is the version i want to test in HermitCore.
NPB3.3.1-MZ-SER
Changes.log
README

b) I included the CmakeLists.txt file in NPB3.3.1-MZ. This file contains the follow sentences:

cmake_minimum_required(VERSION 3.7)
include(../../cmake/HermitCore-Application.cmake)

install_local_targets(extra/NPB3.3.1-MZ)

c) I modified the make.def file in libhermit/usr/NPB3.3.1-MZ/NPB3.3-MZ-OMP/config, with the follow sentences:

F77 = x86_64-hermit-gfortran
CC = x86_64-hermit-gcc

d) I added the follow sentence in the libhermit/CmakeLists.txt file:

#Test and benchmarks
build_external(NPB3.3.1-MZ ${HERMIT_ROOT}/usr/NPB3.3.1-MZ hermit)

e) Finally, I ran the build process of HermitCore:

sudo cmake ..  => OK
sudo make       => ERROR
[80%] Performing configure step for 'NPB3.3.1-MZ'
Not searching for unused variables given on the command line
     --The CXX compiler identification is unknown
Cmake Error in CmakeLists.txt
No CMAKE_CXX_COMPILER could be found

2) Second Configuration

a) I only modified the CmakeLists.txt file in libhermit/usr/NPB3.3.1-MZ. Now, this file contains the follow sentences:

project(hermit-NPB Fortran)
project(hermit-NPB CXX)

b) I ran the build process:

sudo cmake .. OK
sudo make ERROR
[ 80%] Performing configure step for 'NPB3.3.1-MZ'
Not searching for unused variables given on the command line.
-- The CXX compiler identification is unknown
CMake Error at /home/bguala/Escritorio/HermitCore/libhermit/cmake/HermitCore.cmake:72 (enable_language):
  No CMAKE_CXX_COMPILER could be found.

CMake Error at /home/bguala/Escritorio/HermitCore/libhermit/cmake/HermitCore.cmake:72 (enable_language):
  No CMAKE_Go_COMPILER could be found.

Am I forget something?

[stlankes]

Hm, personal I would not use NPB3.3.1-MZ. I prefer NPB3.3.1, which also supports OpenMP.

In libhermit/usr/NPB3.3.1/CmakeLists.txt, I would add a command to call the external tool make. As far as I know, you have to use add_custom_target. It could look like this:

add_custom_target(
   NPB3.3.1
   COMMAND make
   WORKING_DIRECTORY full_path to where Makefile is located
)

[bguala]

The NPB3.3.1-MZ doesn't work. Therefore, I tested NPB3.3.1 with

add_custom_target(
   NPB3.3.1
   COMMAND make
   WORKING_DIRECTORY /home/bguala/Escritorio/HermitCore/libhermit/usr/NPB3.3.1/NPB3.3.1-OMP
)

in libhermit/usr/NPB3.3.1/CmakeLists.txt, but this sentence generates the follow error message:

CMake Error at /home/bguala/Escritorio/HermitCore/libhermit/cmake/HermitCore-Utils.cmake:128 (install):
  install TARGETS given target "NPB3.3.1" which is not an executable,
  library, or module.
Call Stack (most recent call first):
  CMakeLists.txt:13 (install_local_targets)

when I run the command "sudo make". The sintax of add_custom_target is

add_custom_target(Name [ALL] [command1 [args1...]]
                  [COMMAND command2 [args2...] ...]
                  [DEPENDS depend depend depend ... ]
                  [BYPRODUCTS [files...]]
                  [WORKING_DIRECTORY dir]
                  [COMMENT comment]
                  [VERBATIM] [USES_TERMINAL]
                  [SOURCES src1 [src2...]])

I also tested diferent variants of this sentence such as:

add_custom_target(NPB3.3.1 make bt CLASS=S)

but, it doesn't work.

[stlankes]

If I understand it correctly, the application will be built but not installed. The makefile doesn't have an install rule. Maybe you should start with an empty rule to test, if this is the problem. Please add the end following lines to NPB's makefile. The last line contains only a TAB.

install:

[bguala]

I added install: in libhermit/usr/NPB3.3.1/CmakeLists.txt, but when I run sudo make I see

CMake Error at /home/bguala/Escritorio/HermitCore/libhermit/cmake/HermitCore-Utils.cmake:128 (install):
  install TARGETS given target "NPB3.3.1" which is not an executable,
  library, or module.
Call Stack (most recent call first):
  CMakeLists.txt:14 (install_local_targets)

Build NPB implies to execute make BT CLASS=S, for example. Where does this sentence include?. make BT CLASS=S saves the executable bt.S.x in libhermit/usr/NPB3.3.1/NPB3.3.1-OMP/bin. Therefore, Should I delete the sentence install_local_targets(extra/NPB3.3.1) in libhermit/usr/NPB3.3.1/CmakeLists.txt?.

[stlankes]

Hm, difficult to understand. Could send me your configuration files. I will test it on my system,

[bguala]

Yes, of course. These are my files:

CMakeLists.txt contains the sentence build_external.

CMakeLists.txt contains add_custom_target.

[stlankes]

Excuse me, I forgot this request. Do you still need support?

[bguala]

Yes, I do. The last thing I tried was to compile the benchmarks separately, but it did not work.

[stlankes]

Ok, I will do it tomorrow

[stlankes]

Please test the version at https://gigamove.rz.rwth-aachen.de/d/id/JtGNq5LWradWdY

It isn't fully integrated in our toolchain. But it works on our systems. Does it help?

[bguala]

I don't know. I'm traying...

[bguala]

Hello.

I am traying to build NPB in HermitCore again. This time the build process begins, but it ends when performing configure step for xray.

The current hierarchy of project is:

HermitCore/libhermit/usr/CMakeLists.txt: this file contains the sentence:

build_external(BPB3.3-OMP ${HERMIT_ROOT}/usr/NPB3.3-OMP hermit)

HermitCore/libhermit/usr/NPB3.3-OMP/CMakeLists: this file contains the code:

project(hermit-NPB Fortran)

add_custom_target(
BPB3.3-OMP
COMMAND make
WORKING DIRECTORY /Desktop/HermitCore/libhermit/usr/NPB3.3-OMP
)

install_local_targets(extra/NPB3.3-OMP)

NPB3.3-OMP also contains a makefile.

What is xray for??. A simple profiler for Native Client.

Can it be resolved by removing benchamarks???.

[stlankes]

Hm, xray is a simple profiler. You can remove it. Comment out these lines. Does it work for you?
