Loophash and Batchrelax are MPI applications, and are intended to be run under an MPI framework across multiple (dozens to thousands) of processors/nodes. You need to launch them with an MPI launcher program. (Something like “mpirun”, but what you use depends on the MPI framework on your system.) It looks like you simply ran the executable by itself, not with an MPI launcher. Thus it only started node zero, which for these protocols is an “emperor” (or master) node which simply organizes the other nodes and doesn’t do any processing itself. You don’t have any other nodes running, so it just sits around waiting for the non-existent nodes to check in with it.
Talk to your local sysadmin or MPI guru and find out how to run MPI programs across multiple nodes on the cluster you’re using. (Each cluster can be different, so you need to check details with your local cluster expert.)

But I have used the mpirun.My command is mpirun loophash_mpi.mpi.linuxrelease @flags.I have installed the open-mpi in my personal computer.

And in the flags,there is -in:file:silent
##the starting population.What kind of file I need to use as inputfile?I can’t understand the meaning of ( Silent input filename(s). [FileVector]) . -

You need to pass the node specification to the mpirun command. How many processors do you want to use? Which computers are these to be run on? For example, on the one I use, I have to pass “-np 12” to mpirun to get it to spread 12 jobs across the current node. With loophash and batch relax you’ll want to use many more processors (probably hundreds to thousands) spread across a large number of nodes. You’ll need to pass options to split out the run onto those processors. If you don’t, mpirun may just default to running a single instance on the local node, resulting in the errors you see.

The format is a “silent file”. This is a Rosetta-specific file format. A large number of Rosetta protocols can take and output silent files. If you have a bunch of PDBs, the easiest way to create a silent file is probably with the score_jd2 application
score_jd2.default.linuxgccrelease -out:file:silent [silent file name] -out:file:silent_struct_type binary -s [list of PDBs to put into the silent file]The “Silent input filename(s). [FileVector]” description simply means that the -in:file:silent takes a list of files in silent struct format. Generally you only pass a single file, though. (A single silent file can contain multiple different structures – although they should all be related. Basically, the same length, if not the same sequence.)

Thank you!I have solved some of my questions!
This is my running details.It stopped here.Is there anything wrong?Or I just need to wait it to finish calculation?And I just run the mpi in my own personal computer and just have one cpu(dual core).

Unfortunately for you, Loophash (batch relax, too) is a massively parallel application. Instead of just a single master node, it uses multiple masters and then has a master-of-master nodes (the emperor). You’re running into the same problem as before, but instead of a single emperor node sitting around waiting for work, you have an emperor and master, both waiting for nonexistent worker nodes to show up.
When I said dozens to thousands of nodes, I meant it. You’re really not going to be able to successfully run loophash and batchrelax on a single dualcore machine. They’re applications which are intended to be use on large multi-node computational clusters.
If you absolutely need to run them on a dual core machine, I can see if you can fake it, but it will be painful and exceedingly slow. You’re much better off trying to get access to a cluster. If you’re at a university there’s probably one you can get time on, or failing that there are a number of contract clusters out there (Rosetta@Cloud http://rosetta.insilicos.com/ (mentioned for informational purposes only, no endorsement intended or implied) is one such service tailored to Rosetta use, but there are other out there which may fit your needs better.)

Thank you for your reply.
I am a sophomore,and I don’t have the large multi-node computational clusters.I just have one dual core machine.I have no choice.If I still want to run on a dual core machine,What should I do?How can I fake it?I just want to run a small protein like enkephalin. -

Um, are you affiliated with any of the RosettaCommons labs, by any chance?
The reason I ask is that apparently neither loophash nor batchrelax have been released yet. The general public shouldn’t have access to them yet. Only if you are a Rosetta developer or closely associated with a RosettaCommons lab would you be able to compile and run them in the first place.
-
July 26, 2013 at 2:08 am #9133
I got the C files from someone in the lab,and I compiled it by myself.I am not in the lab,I have difficulties in running them,so I turn to you for help. I want to be a Rosetta developer.But actually,I don’t know how to do.

Rosetta isn’t a Free Software/Open Source program in the same model something like Linux is. Instead it’s explicitly licensed directly from the RosettaCommons – a no cost license for academic users, and a for-pay license for commercial use. Because of administrative issues, being a Rosetta developer isn’t really open to the general public. You need to be a member of a RosettaCommons lab, or be closely associated with one of them. All official* Rosetta development needs to be funneled through one of the RosettaCommons member PIs (most of which are listed on the left hand side of https://www.rosettacommons.org/home). If you’re interested in contributing to Rosetta in the long term (as opposed to simply using it), your best bet is to get a position or affiliation with one of those labs (e.g. as a graduate student or postdoc), or at the very least develop a close relationship with one of them.
For your current purposes, I would talk to the “someone in the lab” from whom you got the files. It could be that they got a pre-release version of loophash and batchrelax from a RosettaCommons member collaborator. If that’s the case, they can put you in contact with their RosettaCommons contact, who could possibly provide you with the non-mpi versions of loophash and batchrelax. (Non-MPI version of both are available in the development version, which will run suitably – but more slowly – on a single processor. I’ve actually been informed that the non-MPI batchrelax application was the first version of batchrelax to be developed, and works more reliably than the MPI version; I misspoke earlier when I said the protocol was by default an MPI application.)
*) Official meaning development which is included in the Rosetta releases. My understanding of the license (don’t quote me – I’m not a lawyer) is that development and modification of Rosetta for your own internal use is permitted, a long as you don’t go distributing it to other people without clearing it with the Rosetta licensing people first.

Thank you for your reply.
And do you have the non-mpi versions of loophash and batchrelax?
-
July 29, 2013 at 7:58 pm #9154
I do have access to the developers’ version of Rosetta, but as the loophash and batchrelax applications aren’t mine, I don’t feel comfortable distributing them to others. Again, talk to the person who provided you with the pre-release MPI versions of the programs. The Rosetta developer who provided them would be your best contact in obtaining the non-MPI versions.
Failing that, your best bet is to wait until the programs are officially released. (I unfortunately don’t know when that will be.) In the mean time, you may want to consider other similar approaches. For example, batchrelax is an extension of the FastRelax protocol, and simply running FastRelax with many output structures can do more or less what batchrelax can do, albeit less efficently. Similarly, there are a number of other loop remodeling protocols in Rosetta which can be applied to many of the same problems that loophash is used for. You may want to investigate those, and see if their output will be acceptable.

But I sent email to the person who provided me with the pre-release MPI versions of the programs,he hadn’t replied me for several days.He maybe the person who wrote the loophash and batchrelax.And I guess the non-MPI versions of loophash and batchrelax will not exist in official version,if it is released.I hope you can help me,I just use it to optimize the structure of protein,do some contribution to this field.Thank you!
