[gmx-users] NVT equilibration in vacuum
Hello gromacs users, I am using gromacs to simulate a peptide in vacuum. I was wondering for the NVT equilibration step, are there any particular parameters to be changed for vacuum conditions as there is no position restraining on solvent molecules?

Re: [gmx-users] WG: WG: Issue with CUDA and gromacs
Hi Steffi, Thanks for running the tests; yes, the patch file was meant to be applied to the unchanged GROMACS 2019 code. Please also share the log files from thr failed runs, not just the copy-paste of the fatal error -- as a result of the additional check there might have been a note printed which I was after. Regarding the regression tests, what I would like to have is the actual directories of the tests that failed, i.e. as your log indicates a few of the complex tests at least.

No, I'm doing right now ONLY membrane. There are only lipids in the .gro file with solvataion and the CTL3 is atom of lipid. I just wanted to check if I'm able to create membrane-only system first. If everything will work I'll try to embed protein+ligand in this membrane. If I believe you are using amber ff for the lipids generated using charm GUI, then I should say the nomenclature of the lipid membrane will be in charmm format. Either you must use charmm ff or you have to use lipids for amber ff .. I just download PDB file with membrane cluster structure from charmm-gui. No topology, no parameters at all. Only coordinates. Then I found parameters in amber force field for this DLPC and proceeded both pdb structure and parameters .itp with pdb2gmx. Everything worked.

This assumption can only be made if all hardware threads of the entire node are used the run itself (i.e. in your case 2x22 cores with HyperThreadince hence 2 threads each = 88 threads). -ntmpi 1 -ntomp 1 -pin on; runs > -ntmpi 1 -ntomp 2 -pin on; runs > > - ntmpi 24 -ntomp 1 -pinstride 1 -pin on; runs > - ntmpi 24 -ntomp 1 -pinstride 2 -pin on; runs > > After patch supplied: > - ntmpi 1 -ntomp 22 -pin on; sometime runs - sometimes doesn't* -> > md_run.log at : > https://it-service.zae-bayern.de/Team/index.php/s/ezXWnQ2pGNeFx6T > > md_norun.log at: > https://it-service.zae-bayern.de/Team/index.php/s/wYPY7dWEJdwmqJi > - ntmpi 1 -ntomp 22 -pin off; sometime runs - sometimes doesn't* (ran > before) > - ntmpi 1 -ntomp 23 -pin off; doesn't work* (ran before) > > - ntmpi 1 -ntomp 23 -pinstride 1 -pin on; doesn't work* > > - ntmpi 1 -ntomp 23 -pinstride 2 -pin on; doesn't work* (ran before) > The suspicious thing is that the patch I made only improves the verbosity of the error reporting, it should have no impact on whether the error is triggered or not. Considering the above behavior it seems that pinning (at least the patters tried) has no influence on whether the runs work. Can you please try: -ntmpi 1 -ntomp 11 -pin on -pinstride 1 -ntmpi 1 -ntomp 11 -pin on -pinstride 2 -ntmpi 1 -ntomp 11 -pin on -pinstride 4 -ntmpi 1 -ntomp 11 -pin on -pinstride 8 and -ntmpi 1 -ntomp 22 -pin on -pinstride 1 -ntmpi 1 -ntomp 22 -pin on -pinstride 2 -ntmpi 1 -ntomp 22 -pin on -pinstride 4 And please run these 5 times each (-nsteps 0 is fine to make things quick). Also, please use this patch https://termbin.com/r8kk The same way as you did the one before, it adds another check that might shed some light on what's going on. - ntmpi 24 -ntomp 1 -pinstride 1 -pin on; runs > - ntmpi 24 -ntomp 1 -pinstride 2 -pin on; runs > > * Fatal error: > Asynchronous H2D copy failed: invalid argument > > When compiling, the make check shows that the regressiontest-complex and >

You will certainly not benefit from trying to use multiple GPUs for such a small system. I get a note stating potentially sub-optimal launch configuration, gmx started with less pp Mpi process for node than GPUs available. So the use of GPU is automated depending on the size of the system? mdrun will try to utilize everything it finds, and automatically tune for the best performance, but in your case you definitely only want to use 1 GPU. Also, I can find a line in the log file, "Binary not matching Hardware- you might be losing performance. Please help us understand this more. The last message suggests you have not compiled GROMACS in the best way to maximize performance. At compilation, cmake will recommend what type of hardware optimization to use. Follow its suggestion, or simply do not override it with your own specification. -Justin -- == Justin A.

[gmx-users] Help regarding clustering of conformations
hello, i have the output files of 100ns production simulations. I have treated for PBC. I want to find clusters of the trajectories. This can be done using gmx cluster. But i want to do energy minimization of each snapshot in the trajectory and then make clusters. Is there any command or option or solution for this?

[gmx-users] grompp error: Unknown bond_atomtype
Hello everyone, I would call myself newbie gromacs user and need some help with task that was given to me. I'm supposed to take protein-ligand complex (bounded by covalence bond) and put it into membrane. I'm glad I've created the complex in amber force field. But now I stucked around membrane think. I have created DLPC-only membrane cluster in charmm-gui. I have found parameters for this type of lipid. I did add additional names for atom in atomtypes.atp, include ffbonded_lipid.itp and ffnonbonded_lipit.itp files to forcefrield.itp and put into amber forcefield directory t he lipids.rtp file. Gladly everything went smoothly with pdb2gmx with my membrane. I get topol.top file. Then I wanted to try minimize energy. I've prepared .mdp file and used gromp with: gmx grompp -f minim.mdp -c membrane_solv.gro -p topol.top -o em.tpr Unexpectedly I get error "Unknown bond_atomtype CTL3", though CTL3 is defined in atomtypes.atp and the bond have its parameters inside the ffbond.itp file. It's really strange for me, beacuse I thought that if topol.top file was created there is no possibility to get some troubles with defined atoms, bonds, etc. Where did I make mistake? -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?

Re: [gmx-users] GPU error
Hi Dr Mark System is pretty tiny only with 15000 atoms. 1 GpU is automatically selected. I get a note stating potentially sub-optimal launch configuration, gmx started with less pp Mpi process for node than GPUs available. So the use of GPU is automated depending on the size of the system? Also, I can find a line in the log file, "Binary not matching Hardware- you might be losing performance.
