Uchuu Fast Download Speed

The skun@IAA_RedIRIS server that hosts Uchuu data releases provides a fast download speed through the RedIRIS High Speed Data Transfer Service.

The Uchuu DR1 (Public_DR1), DR2 (Public_DR2), DR3 (Public_DR3) products can be downloaded using FileShare or CLI,

    username: irisplanet@rediris.net
    password: IAADataSet-2022

This command can download all DR1 Uchuu Halos at z=0

$ aspera shares download -i --overwrite=diff --Host=fileshare.rediris.es --user irisplanet@rediris.net -p IAADataSet-2022 --source=/IAA_UCHUU_USERS/Public_DR1/Uchuu/RockstarExtended/halodir_050

And to download all DR2 Uchuu-SDSS galaxy lightcones (and randoms)

$ aspera shares download -i --overwrite=diff --Host=fileshare.rediris.es --user irisplanet@rediris.net -p IAADataSet-2022 --source=/IAA_UCHUU_USERS/Public_DR2/Uchuu_SDSS/uchuusdss_lightcones

This command can browse a directory for DR1

$ aspera shares browse -i --Host=fileshare.rediris.es --user irisplanet@rediris.net -p IAADataSet-2022 --path=/IAA_UCHUU_USERS/Public_DR1/Uchuu/RockstarExtended

And to browse a directory for DR2

$ aspera shares browse -i --Host=fileshare.rediris.es --user irisplanet@rediris.net -p IAADataSet-2022 --path=/IAA_UCHUU_USERS/Public_DR2/Uchuu_SDSS

CLI Troubleshooting: The message "Client unable to connect to server (check UDP port and firewall)" points that you are having a problem with your firewall, i.e., your network is filtering the UDP ports that Aspera needs to use. This port is 33001 UDP and TCP. Please contact your system admin.

Uchuu Standard Download Speed

In case your UDP/TCP ports do not allow you to use Aspera we also offer to download the data through the Skies & Universes browser,

For massive download you want to use wget . This is an example to download all Uchuu 'M200c1e12' catalogues at z=0 (Uchuu halos with M200c > 1e12 Msun/h):

$ wget "ftp://skun.iaa.es/SUsimulations/UchuuDR1/Uchuu/RockstarExtendedM200c1e12/halodir_050/
halolist_z0p00_m200c1e12_*.h5"

Below another example to download alll Uchuu-SDSS galaxy lightcones (and randoms):

$ wget "ftp://skun.iaa.es/SUsimulations/UchuuDR2/Uchuu_SDSS/uchuusdss_lightcones/*"
