Subject: [mcstas-users] Using mcset_ncount(nnn)
Message-ID: <2024BD81-57CE-4C2C-AC71-F4D1EB502BA7@ornl.gov>

Hi,

I have a quick question which I am not sure I found the correct answer for in the docs?

If I use 'mcset_ncount(nnn)? in the mcstas instrument definition with the intent to improve
load balancing on a heterogeneous cluster will the run result reflect the newly set number of
source neutrons (nnn)?

Thanks,

Uli

Hi Uli,


As you have probably figured out yourself, our MPI-approach is quite naive in the sense that:

1) The ?mother? process collects / decides the ?full? ncount of the problem to be simulated (e.g. Nfull)
2) On the k used mpi processors, the partition Nfull / k is simulated

If I understand you correctly, you are asking if one could redefine the ncount in INITIALIZE?


- I guess this should in fact be possible, provided that the same Nfull is simulated over the k processors.


You will of course have to do some logic in the INITIALIZE section to up / downscale the node-dependent ncount as you propose, figuring out how many processors that are of each type and assigning the correct, scaled number locally.


Best
Peter

Hi Uli,

So sorry, this is simply a side-effect of manual directory-creation / markup-editing?

The files are located here:
     http://download.mcstas.org/mcstas-2.7/linux/centos/

- BTW a small tip for everyone on the list: You may find it easier to simply browse your way from http://download.mcstas.org/

Have a nice weekend,
Peter

Hi Peter,

I was not brave enough to click this link in 'http://mcstas.org/download/?...
The page says to use this link for older distribution packages :-)

Thanks so much? wishing you a great weekend too!

Hello, 

I am having some problems with interpretation of mcresplot results. I am
simulating an inverted geometry tof instrument and I placed
Tof_Res_Sample and Res_Monitor in my simulation. I expected to get
energy resolution, something like a plot of dE/E=f(E_transfer), but I
got some Q,E data instead. I am attaching the results. If I should
provide more files or information, let me know, I will send it asap. 

I didn't want to bother You and I really tried to figure it out myself,
but I have to ask for your advice. 

Looking forward to hearing from you, 

Marta Klepacka

Hi,

just installed McStas 3.0 and have the following problem after an 
install on Ubuntu 20.04.

with

cd  /etc/apt/sources.list.d
sudo wgethttp://packages.mccode.org/debian/mccode.list
sudo apt-get update

sudo apt-get install mcstas-suite-python-ng



mcgui wont start and gives the following error message:

/usr/bin/mcgui: 14: [[: not found
Traceback (most recent call last):
 ? File "<string>", line 1, in <module>
ImportError: 
/usr/local/lib/python3.8/dist-packages/PyQt5/Qt/lib/libQt5Core.so.5: 
version `Qt_5.15' not found (required by 
/usr/local/lib/python3.8/dist-packages/PyQt5/Qsci.abi3.so)

I'm completely new to the software, so
perhaps I'm missing something completely obvious.
Any hints would be highly appreciated.

thanks in advance

Richard

Dear Richard,


Based on the ImportError reference to /usr/local/lib/python3.8/dist-packages/, this to me looks like a clash with locally installed Python-modules?

Our Debian-packages rely on the Debian/Ubuntu-provided version of PyQt, Qscintilla etc., you may have installed these earlier as a local version for some other software.

My guess is that if you (as an experiment) rename your /usr/local/lib/python3.8/ folder to e.g. /usr/local/lib/python3.8.GONE mcgui will run just fine.



Best,
Peter

Dear Peter,

thanks for the fast answer.

With your suggestion below I can start mcgui.

Only downside is that now my Jupyter installation is not working anymore.

But I'll try to find a solution for that.

Best,

Richard

Dear McStas users,

I'm writing with a problem, I believe similar to a recent issue (already resolved here https://mailman2.mcstas.org/pipermail/mcstas-users/2021q1/001391.html), however that solution did not help me. After installing McStas 3.0 on Windows 10 (WSL1, Ubuntu 20.04 LTS) I get the following error:

.../McStas$ mcgui

I would be grateful for any help with it.
Kindly,
Micha? Dembski-Villalta

Dear Micha?.


Judging from the last line of the error-message, it looks like the shell-script could be picking up a path containing a space, i.e. Program Files?

Could you try doing e.g. a cd /tmp before attempting to start mcgui to see if this changes anything?

Alternatively you should be able to remove the lines 26-28 in the mcgui shell-script, i.e. replace

else
    export PATH=$LIB/../miniconda3/bin:$PATH
    export LD_LIBRARY_PATH=$LIB/../miniconda3/lib:$LD_LIBRARY_PATH
fi

by

fi

only?


Hope this helps,

Peter

Hello again Micha?,


I successfully reproduced your issue in a virtual machine, and also found a series of workarounds.

1) (As root) I commented out lines 26-28 in /usr/bin/mcgui

2) Next, a problem loading libQt5Core.so.5 appeared:

  Traceback (most recent call last):
    File "/usr/share/mcstas/3.0/tools/Python/mcgui/mcgui.py", line 14, in <module>
      from PyQt5 import QtCore, QtWidgets
  ImportError: libQt5Core.so.5: cannot open shared object file: No such file or directory

  - But in fact the file was present in /usr/lib/x86_64-linux-gnu/ ?! This turned out to be an issue with the kernel shipped
    with Ubuntu 20.04 on WSL, I followed the recommendation from this page:
    https://askubuntu.com/questions/1034313/ubuntu-18-4-libqt5core-so-5-cannot-open-shared-object-file-no-such-file-or-dir

    and ran the command

sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

- This all together allowed mcgui to run, see attachment.


Best
Peter

Dear Micha?.


Judging from the last line of the error-message, it looks like the shell-script could be picking up a path containing a space, i.e. Program Files?

Could you try doing e.g. a cd /tmp before attempting to start mcgui to see if this changes anything?

Alternatively you should be able to remove the lines 26-28 in the mcgui shell-script, i.e. replace

else
    export PATH=$LIB/../miniconda3/bin:$PATH
    export LD_LIBRARY_PATH=$LIB/../miniconda3/lib:$LD_LIBRARY_PATH
fi

by

fi

only?


Hope this helps,

Peter

Dear McStas users,

I?m writing with a problem, I believe similar to a recent issue (already resolved here https://mailman2.mcstas.org/pipermail/mcstas-users/2021q1/001391.html), however that solution did not help me. After installing McStas 3.0 on Windows 10 (WSL1, Ubuntu 20.04 LTS) I get the following error:

.../McStas$ mcgui
/usr/share/mcstas/3.0/bin/mcgui: 14: [[: not found

I would be grateful for any help with it.

Dear McStas users,

Thank you for the help with previous issue, i.e. starting mcgui on Ubuntu 20.04, the solution made mcgui work. However, I encountered another problem, this time with NCrystal - I do not know, whether that is a different part of the same issue, or is it something entirely different. As I understand from the changes in Mcstas 3.0:
"Updated version 2.2.2 NCrystal library from T. Kittelmann (ESS) and X.X. Cai (CSNS), distributed with McStas on Unix
platforms only. With McStas 3.0, NCrystal is more tightly integrated and should run without using ncrystal_preparemcstasdir."
However, I cannot get the NCrystal sample to work, using McStas on Windows 10 (WSL1 Ubuntu 20.04):
"
./PANDA_Michal_DV_draft.c: At top level:
./PANDA_Michal_DV_draft.c:7890:10: fatal error: NCrystal/ncrystal.h: No such file or directory
7890 | #include "NCrystal/ncrystal.h"
      |          ^~~~~~~~~~~~~~~~~~~~~
"

Please find attached the log (together with running mcgui) as well as the .instr and .c files. I would be grateful for any help with it.

Kindly,

Dear Micha?,

Thank you for reporting this issue - which is indeed separate from the mcgui issue from yesterday.

It turns out I must have left out the mcstas-ncrystal-3.0 package from the mcstas-suite-python-ng package? And hence the found issue is likely present on any Debian- or Ubuntu based system.


To solve it, please

1) Install the ncrystal libraries:
sudo apt-get install mcstas-ncrystal-3.0

2) Reinstall the core mcstas-3.0 package:
sudo apt-get install --reinstall mcstas-3.0


After these steps, I was able to compile the instrument, see attachment.

Best,
Peter

Hi,

I ran into a problem with mcgui after an update on a RHEL 7 machine...

The error message is:

I apologize If this issue came up on the list and I missed it? or the fix is documented somewhere...

Any advice on how to fix that?


Best wishes & many thanks,

Uli

Hi Uli,


We did see the issue recently working with colleagues at ISIS and actually did an update of the CentOS / RHEL packages a few days ago.
(The situation is identical for both the 2.7 and 3.0 releases.)


So my best bet is that either

1) getting the fresh miniconda3 RPM from http://download.mcstas.org/mcstas-2.7/linux/centos/mcstas-miniconda3-2.7-rpm64.rpm and force-installing it over the existing

or

2) clearing your yum cache using
yum clean all
, and force-reinstalling with
yum reinstall mcstas-miniconda3-2.7

- ought to fix the issue.


Please try this out - and let me know if you are succesful or not.

Best,
Peter

Subject: [mcstas-users] Video talks from Virtual McStas Seminar organised by
	MLZ
Message-ID: <81A4DA53-40B8-4A4D-B488-DB091B04E330@fysik.dtu.dk>

Dear all,


The McStas team gave 3 talks at an MLZ Virtual McStas Seminar last week, arranged by Peter Link MLZ. The videos are now available on YouTube:

McStas 3.0 - GPU support in McStas (Peter Willendrup)<https://www.youtube.com/watch?v=ZQHiLHeI4Tk>
Abstract: The recent McStas 3.0 marks a big step forward with added support for acceleration on NVIDIA GPUs. The presentation will highlight the main changes between the McStas 2 and McStas 3 series and with emphasis on what modifications are needed to port an existing instrument or component. Finally the presentation will discuss the areas of McStas 3 that are not yet fully developed and mature.

McStas Union components (Mads Bertelsen)<https://www.youtube.com/watch?v=xDwZ_ryPl5M>
Abstract: The McStas Union components is a set of components that are used in together to describe complex parts of neutron instruments where multiple scattering can be an important aspect. The user will describe scattering properties in a modular fashion to describe materials. Complex geometry can be described, allowing hollow regions, windows and similar with full multiple scattering, which is especially useful for simulating sample environments. The talk will have a focus on the practical use of these components, teaching the basic concepts, as well as showcasing what can be achieved.

McStasScript (Mads Bertelsen)<https://www.youtube.com/watch?v=jeM2S4ht9hM>
Abstract: As python has become the main language for scientific software, it was decided to introduce a python interface to McStas called McStasScript. Using McStasScript a user can describe an instrument, perform simulations and analyze the data directly from a python script. This simplifies including McStas in more advanced workflows. The talk will introduce McStasScript and show how it allows using McStas in a new way that appeals to both new and experienced users.

All the best and enjoy,

Peter

Subject: [mcstas-users] Virtual source with fixed-m divergence
Message-ID: <971c0405-169c-2469-b016-5f48e8619e7c@ill.fr>

Dear McStas,

Here is my problem:
I would like to simulate the exit of a cold neutron guide with a source. 
The aim is to concentrate on the instrument optics, without having to 
calculate all the guide from the reactor.
A simplified and quite general description of a guide exit is a beam 
with a fixed "m-value" divergence: for a given wavelength, the width of 
the angular divergence (either box-type, Gaussian or whatever) is 
essentially proportional to the m-value of the guide coating and to the 
wavelength.
If the guide has different supermirror coatings on horizontal and on 
vertical faces, this leads to different angular widths.
I assume the beam characteristics does not depend on the position at the 
guide exit in this approach.
My question is : what is the simplest way to simulate such a secondary 
(or virtual) source in McStas ? I only found components where the 
angular width is geometrically fixed (in degrees), therefore 
wavelength-independent.
Ideally I would also like to include a non-flat wavelength intensity 
distribution, but this can probably be done by adding a Filter_gen after 
the source.
I am thinking of making several calculations at different wavelengths, 
but if anyone knows a all-in-one solution I am interested.

Thierry

Dear Thierry,

The first thing that comes to mind for me is the MCPL_output (which can store an event list at a given point in the instrument) and MCPL_input (which canvas such a file as a source). The weakness of this approach is that the files can become big, and are intrinsically limited in statistics, the strong point on the other hand is that all possible correlations between neutron parameters are preserved.

MCPL_input has the option to ?smear? the events by MC (when repeating the events), i.e. in the form of a ?sphere of confusion?, slightly tuning energy, position and divergence, all at the discretion of the user...

Other than that, one can envision to use any of the simpler analytical sources in McStas, possibly enriched with further adjustments in an EXTEND block (e.g. modify intensity or divergence based on position etc.)

I am also thinking of machine-learning approaches to synthesize a ?semi-analytical? source from the content of an MCPL file, but this is so far not implemented in practice.

Best
Peter

Hi Thierry,

I?m a big fan of making relative comparisons using the simplest possible source.  I first simulate a ?reference? instrument before playing with parameters.  So long as the source characteristics stay the same, any changes in performance can be expressed by dividing the monitor counts for the modified instrument by the monitor counts for the reference instrument.

Consequently, I?d solve your problem by using the Source_div component and have the focus as a variable defined in the INITIALIZE section, e.g.:

DEFINE INSTRUMENT Thierry(lambda=6, dlambda=0.1,m=1)

DECLARE
%{
  double DivSource_m;
  double SourceWid = 0.1;
  double SourceHi = 0.1;

%}

INITIALIZE
%{
  DivSource_m=m*0.1*lambda;
%}

TRACE
COMPONENT Centre = Progress_bar()
  AT (0, 0, 0) ABSOLUTE

/*******************************************************/
/******************* Source ****************************/
/*******************************************************/
COMPONENT source = Source_div(
	xwidth   = SourceWid, 
	yheight  = SourceHi, 
	focus_aw = DivSource_m, 
	focus_ah = DivSource_m,
	lambda0  = lambda,
	dlambda  = dlambda,
	gauss    = 0)
 AT (0,0,0) ABSOLUTE

END

(Please forgive any direct programming errors).

I suspect that there might be a problem with my relative comparisons if you change the source divergence between instruments as the flux at your target might change.  Someone might be able to advise on that.

Cheers,

Andrew

Hi Thierry,

can one realize this by a source that selects the transverse momentum k_x and k_y by a Monte Carlo choice?
Simply ?Extending? the source component?

Regards

J?rg

Hi J?rg,

Yes, this sort of thing is entirely possible. :-)

The EXTEND block is simply glued on ?at the end? of the other stuff the component does within TRACE.

Relevant building blocks are these:

1) The neutron state,
x,y,z,vx,vy,vz,sx,sy,sz,t,p

2) Conversion factors from mcstas-r.h:
#define AA2MS    629.622368        /* Convert k[1/AA] to v[m/s] */
#define MS2AA    1.58825361e-3     /* Convert v[m/s] to k[1/AA] */
#define K2V      AA2MS
#define V2K      MS2AA
#define Q2V      AA2MS
#define V2Q      MS2AA
#define SE2V     437.393377        /* Convert sqrt(E)[meV] to v[m/s] */
#define VS2E     5.22703725e-6     /* Convert (v[m/s])**2 to E[meV] */

3) Our RNG functions like these
rand01()
rand0max()
randpm1()
randnorm()
randtriangle()
randminmax()
randvec_target? functions like they are e.g. used in sources and samples
