Hi Markus, I was gonna ask why don't you guys set up a windows machine and test for the cctbx crash on that? The VC++9.0 compiler is free and if you use the python that comes in a phenix for windows installation the necessary modules are all present.

Trapping NaN or not trapping NaN
by Luc Bourhis 13 Apr '16

13 Apr '16

Richard and I have been hammering at our build system and code to try to solve several crashes on OS X with Xcode 7.3. Several of them came from the fact that we trap NaN whereas Xcode 7.3 aggressive optimisations produce code that may create a NaN but still deliver the correct final result. A trivial example came from cctbx/xray/conversions.h. We have if (f_sq > 0) f = std::sqrt(f_sq); else f = 0; With the version of clang shipping with Xcode 7.3, both branches are evaluated in parallel before selecting the result based on the test f_sq > 0. This is done so as not to stall the pipeline and this can result in much faster code indeed. But that means that every time f_sq < 0, a NaN will be produced, and in the context of our tests, this means we crash. Richard and I avoided the elephant in the room, stop to trap NaN, and as a result came with uglier and uglier fixes. Moreover, we are now at the mercy of the compiler applying such an optimisation to another file at the next update of Xcode, which would then force us to fix the compilation of said file in the relevant SConscript. It’s a loosing game. Thus I reckon that at least on OS X, we should stop trapping NaN. That will leave us with the true clang regression for which I will try to submit reduced cases to the clang bugzilla. Best wishes, Luc

Boost broken on mac?

cctbx can't build without iotbx

Hi all, am I getting mad or % libtbx.configure —only cctbx % libtbx.scons will result in a linking error because of the line marked with <<<<< in cctbx/maptbx/SConscript ? if (not env_etc.no_boost_python): Import("env_cctbx_boost_python_ext") env_bpl = env_cctbx_boost_python_ext.Clone() env_etc.include_registry.append( env=env_bpl, paths=env_etc.cctbx_common_includes) env_bpl.Prepend(LIBS=["asymmetric_map", "iotbx_xplor", "cctbx_sgtbx_asu”, <<<<<<<<<<<<<<<<<<<<<<<<<<<<< "cctbx", "omptbx"]) env_bpl.SharedLibrary( target="#lib/cctbx_asymmetric_map_ext", source=["asymmetric_map_ext.cpp"]) This code was introduced in Dec 2013!!! The only workaround % libtbx.configure cctbx iotbx So much for the modularisation with the libtbx_config’s… Best wishes, Luc

Re: [cctbxbb] sequential revision number from git repo
by markus.gerstel＠diamond.ac.uk 06 Apr '16

Hi Johan, No, not really. .gitversion is not in the repository and only kept (and updated) locally. Basically the logic is: Can I determine the current version number (ie do I have git installed and the repository present) - if so, write .gitversion. Otherwise, attempt to read .gitversion and use the information therein (this covers the route via the installer). Hence, if you download the zip file frm github you will not have a .gitversion file. But really in this case we can assume that the user knows what they're doing. -Markus On 5 Apr 2016 16:34, "Hattne, Johan" <hattnej(a)janelia.hhmi.org> wrote: Would this not mean that .gitversion is updated on every commit, at least if as in our case, it not only records the release version but also the current commit? @Rob: Apologies for my liberal use of “hook”.

CCTBX.XFEL problems with synchrotron stills
by Schulz, Eike-Christian 06 Apr '16

06 Apr '16

Dear all, I am new to serial crystallography and trying to process still images from a synchrotron source (Pilatus 6M detector) using CCTBX. Obviously the process is not glitch-free and I was hoping to get some help here. The indexing routine starts, indexes the images correctly and and produces a log file but no .pickle files are created in the results/000/ directory as described in the wiki entry. I assume that there is a software module that is not properly loaded during the process since I get following error message during indexing: ---------BEGIN Integrate one frame 75 warsaw0048_00075.pickle EFFECTIVE TILING 0 0 2282 2282 Indexing error: No module named cxi_user Is there a way to find out if all dependencies are matched ? I suppose CCTBX.XFEL depends on some (specific) python libraries … ? Or am I completely wrong and the error is something different ? With best regards Eike

sequential revision number from git repo
by R.D. Oeffner 05 Apr '16

05 Apr '16

Hi, We are slowly moving phaser svn to git. One issue that we would like to address is if there is a practical way of conveying a linear commit history from the git repo. One approach is to just count the number of revisions that was made to the master branch in the git repo with "git rev-list --count HEAD" and then pretend that number is a revision number. This enables us to tell users "This bug was fixed after revision 6456 of phaser" rather than "This bug was fixed after commit 29b0a1c... of phaser". Is there any pitfalls with this approach? What workarounds do other people using git come up with?

changes to cctbx we have in ccp4
by Marcin Wojdyr 04 Apr '16

04 Apr '16

Hi All, we have a bunch of changes to cctbx in ccp4. If any of them are of general interest I can push them to svn. They'd need some cleanup before applying, so I'm not attaching any patches for now. - option to use external Boost. It's the same what debian and gentoo distros are doing when packaging cctbx. We change a few lines in the scons scripts and rm cctbx_project/boost/* (but the boost directory itself must be present). We could add an option for it (--use-system-boost ?). - removing -funroll-loops - this option must be a historical leftover. Generally it's better to let compiler decide because unrolling loops may make the program slower as well as faster. I tested it on Phaser a couple years ago. The only noticeable effect of this flag was much bigger binary. - extend --use-environment-flags to handle also CC and CXX. With most of makefiles / build scripts, if the user has multiple compilers installed he selects one with CC=gcc-mp-5 etc. Then if the build script really needs to differentiate between compilers it tries to determine what kind of compiler it is. In cctbx it's the other way around - the --compiler flag tells what kind of compiler it is and the build script guesses executable names. For ccp4 I added in two places in libtbx/SConscript: + if libtbx.env.build_options.use_environment_flags: + if 'CC' in os.environ: cc = os.environ['CC'] + if 'CXX' in os.environ: cxx = os.environ['CXX'] so for _some_ platform/compiler combinations it's possible to use compilers with non-default names. Useful for systems with multiple GCC versions. - probe and reduce are called in mmtbx through phenix wrappers (phenix.probe and phenix.reduce). We prefer to call them directly, but I guess it's not to be changed in cctbx. But after changing the name I also had to remove error checking in mmtbx/validation/clashscore.py that checks return code from phenix.reduce. Reduce itself quite often returns non-zero, it's just that the phenix.reduce wrapper ignores it and always returns 0 (probably not intentionally). - cctbx_project/spotfinder/SConscript - on Windows we have to link dxtbxspotfinder with spotfinder. That's the only such problem when compiling cctbx. OTOH it apparently works for everyone else. I don't know why. It must have something to do with us using MinGW. - A couple of #ifdefs for compiling with MinGW (annlib and gltbx) Marcin

by Billy Poon 30 Mar '16

30 Mar '16

Dear all, On Wednesday, March 30, our servers will be shutdown starting at 7:00 am Pacific for scheduled maintenance in our server room. This will affect, - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) We expect that the servers will be available by 5 pm Pacific at the latest. Bug reports and emails requesting help should be queued and we will receive them once the servers are back online. We apologize for any inconvenience. -- Billy K.

new parallel_map implementation
by Gabor Bunkoczi 29 Mar '16

29 Mar '16

Hi, I have switched over libtbx.easy_mp.parallel_map to use new code that is not susceptible to deadlock when large amounts of data are returned from a worker process. This also means that parameters added to parallel_map to prevent exactly this are no longer necessary (but will be respected), although unlikely to influence performance so much to warrant changing existing code. I have run all tests, but unsure how well this gets tested by regression test, so please let me know if you come across something that is amiss. BW, Gabor
