Hi, What is the best way to run Autobuild if I need to run it on hundreds of datasets (through command-line)? I have a single machine with 24 cores and access to a cluster with 128 cores (on parallel; accessible only through PBS script). Each Autobuild job with nproc=4 on a single core machine takes ~12 hours to run (nproc > 4 wouldn't make any difference in the speed of computation?!). However, I read that I could set nproc=10 (or more) and run on parallel ( https://www.phenix-online.org/documentation/reference/autobuild.html#paralle...). When I tried the same through PBS script, I got the following error, XXXXXXXXXXXXXX Running up to 1 jobs in parallel... with total of 3 jobs Splitting work into 3 jobs and running with 1 processors using qsub background=False nproc=20 background=False in ~phenixWorkingDir/1yya/part1/8tim/AutoBuild_run_5_/TEMP0 Final job will be run with sh with background=True Starting job 1...Log will be: ~phenixWorkingDir/1yya/part1/8tim/AutoBuild_run_5_/TEMP0/RUN_FILE_1.log Traceback (most recent call last): File "~opt/phenix-1.9-1692/phenix/phenix/autosol/AutoBaseExtend.py", line 989, in DoNextMethod self.CarryOutBest() # to be obtained after it is finished File "~opt/phenix-1.9-1692/phenix/phenix/autosol/AutoBaseExtend.py", line 2147, in CarryOutBest getattr(self,str(self.application_method))() # call this fn File "~opt/phenix-1.9-1692/phenix/phenix/wizards/AutoBuild.py", line 2364, in AutoBuild_build_cycle self.AutoBuild_rebuild_cycle_run() File "~opt/phenix-1.9-1692/phenix/phenix/wizards/AutoBuild.py", line 4647, in AutoBuild_rebuild_cycle_run always_reuse_model=always_reuse_model) File "~opt/phenix-1.9-1692/phenix/phenix/wizards/AutoBuild.py", line 7452, in AutoBuild_build_refine mtz_file=mtz_file,mtz_ref_file=mtz_ref_file) File "~opt/phenix-1.9-1692/phenix/phenix/wizards/AutoBuild.py", line 7696, in run_standard_build_in_parallel r.run(out=sys.stdout) File "~opt/phenix-1.9-1692/phenix/phenix/autosol/run_group_of_wizards.py", line 294, in run self.start_run(run_file,last=is_last) File "~opt/phenix-1.9-1692/phenix/phenix/autosol/run_group_of_wizards.py", line 604, in start_run cmd+" "+self.add_double_quote(run_file,escape_space=False)).raise_if_errors() File "~opt/phenix-1.9-1692/cctbx_project/libtbx/easy_run.py", line 37, in raise_if_errors raise Error(msg) RuntimeError: child process stderr output: command: 'qsub background=False nproc=20 "~phenixWorkingDir/1yya/part1/8tim/AutoBuild_run_5_/TEMP0/RUN_FILE_1"' /bin/sh: qsub: command not found XXXXXXXXXXXXXX Please let me know if I can share eff and log files of the run.
