NLO gridpacks?
A possibly silly question: How can I generate a gridpack for an NLO process? Adding ".true. = gridpack" to the run_card.dat doesn't seem to trigger gridpack generation when calling generate_events.

Dear Josh,
There is no special gridpack mode for NLO event generation.
However, you can easily create a "gridpack" yourself. What you have to do is the following:
1.) Generate and output the process as you normally do.
2.) When you do the launch of the NLO event generation, set the parameter in 'nevents' to zero (in the run_card) and the parameter req_acc to 0.001 (also in the run_card). This will skip the event generation step, but does create the grids with a 0.001 relative precision (basically enough for infinite number of events) that can be used to generate events later on. If you want to generate less than a total of 1M events, you can increase the req_acc to 1/sqrt(number of events) so that the grid setup step is slightly faster. Once the run is done, you have a "gridpack". (Just tar the whole MG5_aMC directory, including the process directory).
3.) From the grids that you just generated, you can generate any small number of events in many bunches "by hand":
a.) set the nevents parameter in the run_card back to the number of events you want to generate in the bunch
b.) set the iseed parameter in the run_card to a non-trivial number
c.) execute the command:
./bin/generate_
and this will generate the small number of events from the grids created before.
Note that you probably want to run the event generation with the gridpack on a single CPU core (and not on multi-core or in cluster mode), otherwise there is not really a point in generating a gridpack in the first place ;-) . This can be changed in the Cards/amcatnlo_
Best regards,
Rikkert

Hi Rikkert,
Thanks, this seems to work for the event generation.
Is there a way to do something similar for Madspin? At the moment it seems to recalculate and recompile everything each time I generate new events.
One other point is that it would be extremely useful to have the equivalent eg. of the clean4grid script provided for the LO gridpacks (Or at least some instructions on which files can be safely omitted from the tarball, perhaps we can even use clean4grid directly as is?). In general we would like to minimize the number of files which we have to untar on the grid worker nodes.
Thanks,
Josh

Hi Josh,
Concerning MadSpin,
we have implemented one option in this direction.
if you place in the mad spin_card.dat the following line
set ms_dir PATH
Then if PATH doesn't exists, it creates it but if it exists it uses the information of the previous run.
You can therefore create that directory at the same time as your gridpack and reuse the information.
Cheers,
Olivier

Dear Josh,
There is no clean4grid file for the NLO runs.

Hi Olivier,
When I try this with madspin, the first run computes/compiles everything and then succeeds to decay the events, but the second run fails with a python error. Full details below.
By the way, I assume that I need to generate at least a small number of events in order to initialize everything in Madspin. I see that for my process it was using 75 events to calculate the max weight, etc. Is this number constant, or is it process and/or decay-dependent. (Want to understand if we can safely just generate 100 events at the compilation stage in general as part of our gridpack creation scripts.)

Hi Josh,
I succeed to reproduce your problem and you will find the associate patch below (This will be part of the next release):
>By the way, I assume that I need to generate at least a small number of events in order to initialize everything in Madspin.
>I see that for my process it was using 75 events to calculate the max weight, etc. Is this number constant, or is it process and/or decay-dependent.

If you do the following
generate p p > z [QCD]
add process p p > w+ [QCD]
Then it needs 150 events (75 of each type)
Typically 75 events are enough to have a good estimate of the maximum weight required for the computation, but I personally tend to increase this number manually (to 100-150) if I have to generate very large sample, this typically allows to have a better estimate of the maximum weight which in returns speed up the computation of the decay.
Cheers,
Olivier

Hi Rikkert,
Although the NLO "gridpack" creation appeared to work, on further testing I have run into a serious problem.
It seems that the absolute path of the original folder used to generate the process is hardcoded in various places. The extracted tarball is able to generate events only as long as this path is still accessible. If I remove the original folder, the generation does not work nay more.
I tried changing mg5_path in Cards/amcatnlo_
I still get errors as below. Can you confirm that this is a problem and/or advise all the places where I need to remove/replace the original path in order to make this work?

Hi Josh,
This looks like to me a problem that Paolo face recently as well and that i just fixed in the development version.
Paolo can you confirm if this is the same problem? and then that it should indeed work with the future version 2.1.0?
Cheers,
Olivier

Hi all,

yes it seems to be the very same problem, so it should be fixed now.
Cheers.

Hi Olivier,
Testing with 2.1.0 and things are indeed working properly now as long as I don't use MadSpin.
For Madspin it seems there are still a few places where the absolute path is being persisted inside the pickle file. When I try to run from a tarball with the original folder moved away (and mg5_path properly reset) I get an error as below.
Thanks,
Josh

Hi Josh,
Indeed I never think that the MadSpin directory can be moved as well.
So this is the patch to make it work: This is going to be part of 2.1.1
Thanks a lot for your help,
Olivier

Thanks.
With the patch this is now working as expected.
Will let you know once we've tried actual grid production.
Can you help with this problem?
Provide an answer of your own, or ask Josh Bendavid for more information if necessary.
