No, but it should be easy to write a Python function to do that. Feel free to post such functions on the mailing list if you decide to write them Matthias On Mar 19, 2013, at 7:15 PM, Francisco Cordobés <ghiret@gmail.com> wrote:

Hi,

Thanks.

I have managed to get the bits you mention working. I was just wondering if pyalps can also generate automatically PBS queuing files too as so far I have been doing it by hand. I can always adapt my own python code for that, but if it's already in pyalps, it would be quicker.

Thanks. Francisco Cordobes

Hi Francisco,

We have tutorials that show the use of the MPI version of the ALPS codes. Just add the --mpi option to the command line and the Monte Carlo codes run nicely in a parallel way. You don't need anything special for integration with PBS, except that you should remember to set a time limit that is shorter than the time limit of the queue so that the code can still write a checkpoint.

Tama Ma <pingnang@phys.ethz.ch> is finishing a new and much faster worm code and you might want to get in touch with him regarding that code.

Hi to all,

I am planning on running some large 2D Bosons simulations with ALPS in a cluster. Specifically I will we using the worm algorithm(and dir_loop for some checks). The cluster I am running my simulations in uses a PBS queuing system. All the tutorials and examples I have seen online are for single machine or assuming one doesn't have to use a queuing system. Is there any PBS functionality implemented in pyalps?

Also, and this is a practical question, for running large simulations with ALPS, I understand from the examples and documentation that the best way to do it is to set a very large number of sweep steps and then run it for a fixed time. After that time check if the measurements I am interested in have converged and if not, run it for a bit longer. Is that the best option or is there a better way of doing it?

Thanks in advance,

Francisco Cordobes
