v3 v4 5 5 6 6 ---- 7 = 5/5/2015 Transfert très haut débit TGCC-IDRIS = 8 9 {{{ 10 De: Sébastien Denvil 11 Objet: [Platform-users] Transfert très haut débit TGCC-IDRIS 12 Date: 5 juin 2015 11:47:57 UTC+2 13 14 Bonjour, 15 16 pour information, il est maintenant possible d'utiliser un réseau à très haut débit (10 Gbps) pour transférer des fichiers entre le TGCC et l'IDRIS. 17 On obtient à présent un débit de 150 Mo/s, sans cela le débit maximal était de 35 Mo/s. 18 La procédure à suivre pour bénéficier de ce réseau est accessible depuis les liens en bas de ce message. 19 20 Le réseau des Centres de Calcul Français (CCFR) est un réseau dédié à très haut débit, qui interconnecte les trois centres de calcul nationaux CINES, IDRIS et TGCC. 21 Ce réseau CCFR est mis à la disposition des utilisateurs pour faciliter les transferts de données entre les centres nationaux. 22 Sont raccordées sur ce réseau les machines Curie au TGCC, Ada et Adapp à l'IDRIS. Le CINES sera intégré dans les prochains mois. 23 24 A l'IDRIS: 25 http://www.idris.fr/faqs/reseau-ccfr.html 26 27 Au TGCC, intranet CEA uniquement: 28 https://www-tgcc.ccc.cea.fr/fr/tgcc/User_documentation.html 29 30 bonne journée. 31 Sébastien 32 -- 33 }}} 7 34 = 4/6/2015 : compiler change on Ada-IDRIS = 8 35 {{{ 9 36 Dear all, 10 37 11 Because of bad results with the compilation environment intel/2013.1, we still advise everyone to go back to the previous one, intel/2013.0, as already stated by Laurent Fairhead on May 5th, 2015. 38 Because of bad results with the compilation environment intel/2013.1, we still advise everyone to go back to the previous one, intel/2013.0, 39 as already stated by Laurent Fairhead on May 5th, 2015. 12 40 13 41 We will put this environment back in the default IPSL environment on ada. 14 42 15 More precisely, the file ~rpsl035/.bash_login will be modified to point towards the validated environment including intel/2013.0. This will take effect on Tuesday, June 9th, 2015, at 2 pm. 43 More precisely, the file ~rpsl035/.bash_login will be modified to point towards the validated environment including intel/2013.0. 44 This will take effect on Tuesday, June 9th, 2015, at 2 pm. 16 45 17 If you followed the recommendations (https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocBenvAidris), you won't have anything to do, otherwise use ~rpsl035/.bash_login as a model to modify your own .bash_login file. 46 If you followed the recommendations (https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocBenvAidris), you won't have anything to do, 47 otherwise use ~rpsl035/.bash_login as a model to modify your own .bash_login file. 18 48 19 libIGCM tag v2.6 will also point towards this file. You have to update to this libIGCM tag. See https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM for more information. 49 libIGCM tag v2.6 will also point towards this file. You have to update to this libIGCM tag. 50 See https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM for more information. 20 51 21 Be aware that, even with the environment intel/2013.0, there are still a few errors in some variables with the IPSLCM5A model. We don't support it any more on ada. Please use IPSLCM5_v5 instead, since it has been checked. 52 Be aware that, even with the environment intel/2013.0, there are still a few errors in some variables with the IPSLCM5A model. 53 We don't support it any more on ada. Please use IPSLCM5_v5 instead, since it has been checked. 22 54 23 55 Have good computations on ada! Don't forget to check your results! … … 29 61 30 62 {{{ 31 In order to fix problems related to NetCDF writing/reading encountered on scratchdir filesytem on Curie machine, we are going to switch compilation and running environment with new NetCDF version netcdf/4.3.3.1_hdf5_parallel, nco/4.4.6 and cdo/1.6.7. 63 In order to fix problems related to NetCDF writing/reading encountered on scratchdir filesytem on Curie machine, 64 we are going to switch compilation and running environment with new NetCDF version netcdf/4.3.3.1_hdf5_parallel, nco/4.4.6 and cdo/1.6.7. 32 65 33 Except for IPSLCM5A model (see below), the change of NetCDF version (switch from 4.2 to 4.3.3.1) has been validated and the reproducibility of the results has been checked for all of models and configurations available through "model" command in modipsl. 34 We strongly advice you to switch with this new compilation and running environment which will be available from June, 9th, 2 pm. To do that, here are instructions to follow : 66 Except for IPSLCM5A model (see below), the change of NetCDF version (switch from 4.2 to 4.3.3.1) has been validated and 67 the reproducibility of the results has been checked for all of models and configurations available through "model" command in modipsl. 68 We strongly advice you to switch with this new compilation and running environment which will be available from June, 9th, 2 pm. 69 To do that, here are instructions to follow : 35 70 36 71 1) Environment … … 43 78 For models and configurations extracted before this date, you will have to : 44 79 - compile (or compile again after a gmake clean) using the new environment (see 1)). 45 - update your libIGCM version in order to use new tag libIGCM_v2.6. Here is information about the update of libIGCM version: http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM 80 - update your libIGCM version in order to use new tag libIGCM_v2.6. 81 Here is information about the update of libIGCM version: http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocLfaq#HowdoIuseadifferentversionoflibIGCM 46 82 47 83 Particular case of v6 configurations using XIOS output library : to compile (or compile again) with the new environment, you have to modify following files : … … 57 93 58 94 3) IPSLCM5A : particular case 59 IPSLCM5A model peforms results which are different from NetCDF 4.2 to 4.3.3.2. If you want to keep exactly the same results, don't change anything in your environment and don't update your libIGCM library. 95 IPSLCM5A model peforms results which are different from NetCDF 4.2 to 4.3.3.2. If you want to keep exactly the same results, 96 don't change anything in your environment and don't update your libIGCM library. 60 97 61 If you have any simulations which are running, you have also the possibility to not change anything and to keep the previous environment (beware the automatic change : case 1.1 above) : you have to know there is a risk to obtain corrupted files. 98 If you have any simulations which are running, you have also the possibility to not change anything and 99 to keep the previous environment (beware the automatic change : case 1.1 above) : you have to know there is a risk to obtain corrupted files. 62 100 63 101 A mail will be sent on June, 9th afternoon once all of these changes will be effective.
