Re: Zero-Kelvin XS data

Hello, i would also be interested in those 0K libraries. Reading the serpent Wiki, I came across this statement about dbrc card: "This input could be given without any nuclides before version 2.1.32. Then DBRC was not used at all." What is its exact meaning? That setting the DBRC card without also s...

Re: Looking for Serpent cross section directories

Dear Riku, I m talking about the production of the thermal scattering part of the file lwtr_EDF71.ace in the package (endfb71_edep.tar.gz). I m not after the additional energy deposition data. I went back in the Serpent-v1.1.7 documentation and found that indeed NJOY99.364 was used then....I just wa...

Re: Looking for Serpent cross section directories

Hello, could you give a bit of information on how you have produced the thermal scattering libraries (njoy version, possibly an input). NJOY evolves quickly these days and it seems that some significant differences can be obtained. FYI, generating my own Sab lib based on the ENDF/B-VII.1 endf files,...

Re: Looking for Serpent cross section directories

Dear Ana,

I would like to have access to the ENDF/B-VII.1 library (endfb71_edep). How should I proceed?

Let me know,

Thank you,

Re: Serpent 2 scalability benchmark

Jaakko, our cluster has two processors per node for a total of 44 cores per node, 88 cores when enabling hyperthreading. Hence the initial use of two mpi tasks per node, binding the memory to each mpi task as suggested in the wiki. But I did what you recommended: use a single MPI task, but increasin...

Re: Serpent 2 scalability benchmark

Hello, in the framework of a M&C2021 paper, I m comparing the performance of MCNP and SERPENT for single statepoint (no depletion) 2D burnt assembly calculations (large number of isotopes but low number of detectors). I m using Serpent v2.1.29. I have access to a cluster allowing for up to ~352 cpus...

Re: sensitivity coefficient calculations

Thanks!

Any idea when it might be included (rough time estimate)?

sensitivity coefficient calculations

Dear Jaakko, I was wondering if the iterated fission probability methods implemented by Manuele Aufiero in his version of SERPENT have been propagated into the generic version of SERPENT2. I couldn't find anything about it on the forum. If it is the case, could you tell me from which version and wha...

Re: serpent in SGE queuing system

Dear all, I m using SERPENT-v2 on a cluster where the ressources are handled by a SGE queuing system. I m running SERPENT-v2 within some scripts driving branch calculations, the end goal being the generation of few group cross sections. Is there an easy way to obtain either from SERPENT-v2 or from t...

Re: ICSBEP Benchmarks

Ville, Jaakko,

Good to know. I will generate inputs for Flattop and ZPR6/10 ZPR 9/34 (benchmark version in ICSBEP).

If you are interested, I ll make them available to you (and whoever may be interested) then.

Thanks!

Mathieu
