Last week, we bolstered our HTCondor cluster by adding 24 new servers, resulting in an additional 3072 computing slots. These servers have been integrated into our existing immersion cooling system, which has been in operation at PIC for the past seven years.
PIC included in the updated ICTS Map
The Council for Science, Technology and Innovation Policy of the Ministry of Science and Innovation has approved the update of the Map of Singular Scientific and Technical Infrastructures (ICTS) of Spain for 2021-2024 with the incorporation of four new infrastructures, including PIC.
PIC joined the Spanish Supercomputing Network (RES) in 2020, an infrastructure that connects 14 supercomputing centers in Spain and since 2007 has been providing high-performance computing services to the scientific community. The RES is recognized as an ICTS by the Ministry of Science. As of today, PIC, as a node of this distributed infrastructure, also obtains this recognition.
The inclusion of PIC in the new ICTS map is an important milestone for the center, as it recognizes the work of our center during almost two decades in large-scale scientific data analysis and will open new avenues for establishing collaborations with research groups facing data analysis challenges, and for funding these activities.

PIC updated network to 200Gbps
The experiments to which PIC gives resources and support need more and more network bandwidth every day. For this reason, we started two years ago to plan the migration to a 200Gbps network connection that today finally was applied. We multiplied by 10 our network capacity by updating also our internal network by adding more redundancy and better monitoring.
The implemented solution is based on Arista devices and the migration process has been done with the collaboration of SATEC. We really would like to thank them for their help.
The update was possible with the funding for the acquisition of technical equipment for science of the national program for infrastructures and technical equipment for science (national plan i+d+i 2017-2020) from the Ministry of Science, Innovation and Universities, for the project Ref. EQC2019-006020-P: “Actualización de la infraestructura de red para mejora de los servicios de datos multi-disciplinares en el PIC”.
Gaia mission’s EDR3 available on Cosmohub
The CosmoHub service at PIC now provides the Early Data Release 3 (EDR3) of the Gaia mission. The early access is possible because PIC recently became one of the affiliated sites of Gaia.
Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy.
In its now available third data release, the object catalog features 1.8 billion objects with unprecedented positional and radial velocity measurements.
You can access the data as part of the public catalogs distributed through CosmoHub.
PIC finished the contribution to Euclid’s GSIR
Euclid’s Ground Segment Implementation Review is an official ESA’s review of the status of the Ground Segment of the project, including the SGS (Science Ground Segment) to which PIC belongs.
PIC contributed to the data package for the Data Processing Panel, which shall assess the status of the Processing Functions (PF) as well as the ability of the SGS to produce and distribute Q1 data products. In order to demonstrate this, the SGS simulated and processed the equivalent to a full day of observation (~10 square degrees). PIC played a key role in this effort, providing the input catalogs, running part of the simulations and producing the documentation relative to the Simulations PF.
The GSIR production (SWF1 & 2 & 3) laid the groundwork for the much more ambitious Scientific Challenge 8 Main Area production, taking place in mid 2021, which will cover ~600 square degrees. Image by H. Aussel.
Dark Energy Survey Data Release 2
The object catalog of the Data Release 2 (DR2) of the Dark Energy Survey (DES) has been ingested into the CosmoHub service. DES is based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4-m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DR2 consists of single-epoch and coadded images, a source catalog derived from coadded images and associated data products assembled from 6 years of DES science operation. The release includes data from the 5000 deg2 wide-area survey covering the southern Galactic cap in 5 broad photometric bands.
The now available catalog consists of 691,483,608 objects with about 480 parameters. The total size of the catalog is ~3 TiB. The DES DR2 catalog is available for exploration and download at cosmohub.pic.es.

PIC puts computing capacity at the service of the COVID-19 research
PIC is putting its computing capacity at the service of the COVID-19 research.
PIC has been running clients of the Folding@Home collaborative computational project in part of its GPU nodes since April 1st. These nodes are normally used by IFAE researchers to analyze astrophysics or particle physics data and now they have been reconfigured to simulate protein folding as part of the Folding@Home worldwide network.
The Folding@Home project uses computer simulations to understand how proteins fold into 3D shapes to perform various functions. Viruses have proteins that they use to suppress our immune systems and reproduce themselves. To help tackle coronavirus, the simulations aim to understand how these viral proteins work to help design therapeutics to stop them.
In the coming days, the amount of resources at PIC devoted to the Folding@Home effort are expected to grow substantially, as the LHC experiments at CERN roll out a coordinated effort to dedicate part of the world-wide LHC data processing infrastructure to COVID-19 research boosting Folding@Home computing capacity. As one of the nodes in the LHC infrastructure, PIC will participate in this initiative. The results of the simulations will be published in the open repository Zenodo, run by CERN.
The Folding@Home project has got a lot of attention in the last weeks and thousands of volunteer computing resources are joining this common effort. More than one million computers are now part of the system, adding up to an estimated computing capacity of 1.5 exaflops, ten times higher than that of the world’s most powerful supercomputer.
On the other hand, IFAE is preparing new projects to use innovative technologies developed for research in particle physics in COVID-19 research, such as the detection of virus biomarkers in blood using single-photon detectors. Other projects in preparation will use the PIC calculation capacity for epidemiological studies and deep learning.
KiDS, Legacy Surveys DR8, COSMOS and more, now available in CosmoHub
A few days ago, we celebrated the 3rd anniversary of the rebirth of CosmoHub on its Big Data platform. As you might know, CosmoHub started as a tool for the distribution of PAU catalogs. Because of the limited data volume this task was achieved by an instance of a SQL relational database capable of handling datasets in the low Terabyte range. Since its beginning, CosmoHub has proven to be very useful for other surveys. The immense increase in data, that will soon reach a few 100s of Terabytes, finally led to the migration to Hadoop. The migration entailed a massive boost in performance and many new features of which you can take advantage today.
In a nutshell, in its most recent incarnation CosmoHub (https://cosmohub.pic.es) is a web platform for the interactive exploration and distribution of massive cosmological datasets. It serves dozens of catalogs to hundreds of users. Further, it has become the reference access point to the PAU catalogs and the synthetic galaxy catalogs derived off the Euclid Flagship dark matter simulations.
We wanted to celebrate this amazing achievement with all the CosmoHub supporters, and what better way of doing this than making available the largest set of public catalogs since our launch.
Since today, there are 9 new public catalogs available:
- DEEP2 redshift catalog DR4: The survey targeted ~50,000 distant galaxies in the redshift range 0 < z < 1.4, utilizing the DEIMOS spectroscopic on the Keck II telescope.
- ZEST: Zurich Structure & Morphology Catalog from a COSMOS sample
- KiDS DR4: provides reprocessed pixel and catalog data products for a roughly 1000 square degrees of the sky.
- COSMOS2015: contains precise photometric redshifts and stellar masses for more than half a million objects over the 2deg2 COSMOS field.
- DESI Legacy Survey DR8: 14,000 square degrees of extragalactic sky visible from the northern hemisphere in three optical bands (g,r,z) and four infrared bands.
- CANDELS Bulge-disk decompositions: A catalog of polychromatic bulge-disk decompositions of ~17.600 galaxies in CANDELS.
- DES Y1A1 gold catalog: ~137 million objects detected in co-added images covering ~1800 deg 2 in the DES grizY filters.
- DES Y1A1 morphology catalog: structural and morphological catalogue for 45 million objects selected from the first year data of the Dark Energy Survey (DES).
- VIPERS (photometry and spectroscopy): second and final data release (PDR-2) of the VIMOS Public Extragalactic Redshift Survey (VIPERS).
