Problems installing IMP 2.2.0
by Davide Baù 23 Jul '14

23 Jul '14

Hi, I tried to install imp 2.2.0 on a mac and on a linux machine. It failed on both machines. First I run: > cmake ../imp -DCMAKE_BUILD_TYPE=Release -DIMP_MAX_CHECKS=NONE -DIMP_MAX_LOG=SILENT -DCMAKE_CXX_FLAGS="-fopenmp" and then: > $ cat CMakeError.log > Performing C++ SOURCE FILE Test IMP_COMPILER_HAS_AUTO failed with the following output: > Change Dir: /usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp > > Run Build Command:/usr/bin/make "cmTryCompileExec1534889314/fast" > /usr/bin/make -f CMakeFiles/cmTryCompileExec1534889314.dir/build.make CMakeFiles/cmTryCompileExec1534889314.dir/build > make[1]: Entering directory `/usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp' > /usr/bin/cmake -E cmake_progress_report /usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp/CMakeFiles 1 > Building CXX object CMakeFiles/cmTryCompileExec1534889314.dir/src.cxx.o > /usr/bin/c++ -fopenmp -DIMP_COMPILER_HAS_AUTO -o CMakeFiles/cmTryCompileExec1534889314.dir/src.cxx.o -c /usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp/src.cxx > /usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp/src.cxx: In function ‘int main()’: > /usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp/src.cxx:10:8: error: ‘a’ does not name a type > make[1]: *** [CMakeFiles/cmTryCompileExec1534889314.dir/src.cxx.o] Error 1 > make[1]: Leaving directory `/usr/src/imp/imp-r2.2.0/CMakeFiles/CMakeTmp' > make: *** [cmTryCompileExec1534889314/fast] Error 2 > > Source file was: > /** > * ile nothing.cpp > * rief nothing > * > * Copyright 2007-2014 IMP Inventors.

Parallelize code
by Davide Baù 16 Jul '14

16 Jul '14

Hi, I have set up a Brownian dynamics optimizer as follow: > m = IMP.kernel.Model() > > # Brownian Dynamics > bd=IMP.atom.BrownianDynamics(m) > bd.set_maximum_time_step(1000) > > for i in range(1, nrounds): > e = bd.optimize(10) Is it possible in IMP to parallelize the code to make it faster? I have seen that there is the possibility to use OpenMP but I am not really sure how to implement it. Thanks, Davide

Fwd: [IMP-build] IMP nightly build results, 2014-06-23
by Barak Raveh 23 Jun '14

23 Jun '14

It seems the build works except with Mac. Can someone that regularly builds on Mac help? It is probably just a matter of introducing #include <Particle.h> in the right place - it was previously included through <Model.h> (and it doesn't have to). I don't know why it's Mac specific.

latest commits - heads up
by Barak Raveh 22 Jun '14

22 Jun '14

I made a commit that is supposed to speed up a bit some major kernel and core classes (Model, Particle). No critical changes, it was mainly inlining some methods and preventing redundant object creation. All tests seem to work as before but better wait for nightly tests before updating. Let me know if any problems arise or better yet, if things work faster :) though it might not benefit every piece of code, it is based on profiling my own code. Barak

faster RigidBody::get_reference_frame()
by Barak Raveh 18 Jun '14

18 Jun '14

Hi, right now RigidBody::get_reference_frame() is a common yet expensive operation (from profilng), especially within scores. The reason seems to be that IMP saves the quaternion, but not the rotation matrix. Would it make sense to save a cache of the rotation matrix that would update if needed? Or is it possibly that memory cost would be too high? -- Barak

before I change - anyone objects that Object::do_destroy() be made protected (instead of public) ? -- Barak

disabling swig build

We used to have a cmake option to disable swig build - does this option still exist? If so, what should I write in cmake? Much appreciated, Barak

c++ 11
by Barak Raveh 23 May '14

23 May '14

What is our current policy regarding c++-11 - can we use (or are we already using) c++-11 features that are already well established for 3-4 years. I am particularly craving for the auto keyword :) There's a nice list by the way of c++ 11 support status by compiler versions in the following links: https://gcc.gnu.org/projects/cxx0x.html http://msdn.microsoft.com/en-us/library/hh567368.aspx http://clang.llvm.org/cxx_status.html -- Barak
