Hmm. It looks like all of the Cuda tests are failing. Do the cuda test programs such as deviceQuery, which should be in the cuda sdk, work correctly?

[Jack Shultz]

I am having trouble compiling the sdk

It was missing the library path.

[Jack Shultz]

I am trying to compile gromacs openmm now and it does not seem to compile md_openmm. I set the library path

$LD_LIBRARY_PATH

I think the problem is I only have double precision libraries

[root@localhost build_openmm]# ls /usr/local/openmm/lib/
libOpenMM_d.so libOpenMMFreeEnergy_d.so libOpenMMFreeEnergy_static_d.a libOpenMM_static_d.a plugins

Is there a way to build single precision?

[Michael Sherman]

Jack, the "_d" stands for "Debug" - those are debug libraries, not double precision. You need to change the "Debug" to "Release" in the CMake file to build the release libraries. Regards, Sherm

[Jack Shultz]

You are right. I switched from Debug to Release in cmake advance options.

[root@localhost build_openmm]# ls /usr/local/openmm/lib/
libOpenMM_d.so libOpenMMFreeEnergy_d.so libOpenMMFreeEnergy.so libOpenMMFreeEnergy_static.a libOpenMMFreeEnergy_static_d.a libOpenMM.so libOpenMM_static.a libOpenMM_static_d.a plugins

Still having trouble compiling gromacs. I copied these source files, md_openmm.h, md_openmm.cpp md.c over to the src/kernel on my gromacs distribution. If does not compile unless i comment out the preprocessor condition

/*
#define USE_OPENMM
#ifdef USE_OPENMM
*/

#include "md_openmm.h"

/*
#endif
*/

but then i dont see md_openmm among the binaries. Does it just build as mdrun?

I tried compiling it with this flag hoping it would see this header
./configure CPPFLAGS="-DUSE_OPENMM"

But it did not compile

> Does it just build as mdrun?

Correct. We manually rename it to mdrun-openmm.

After copying the modified files for OpenMM into your Gromacs source directory, did you remember to rerun automake and autoconf? That's necessary, since one of the modified files is a Makefile.am.

I'm not sure how to regenerate the build system

[root@localhost gromacs-4.0.7]# automake
aclocal.m4:14: error: this file was generated for autoconf 2.61.
You have another version of autoconf. If you want to use that,
you should regenerate the build system entirely.
aclocal.m4:14: the top level
autom4te: /usr/bin/m4 failed with exit status: 63
automake: autoconf failed with exit status: 63
