The Spanish Supercomputing Network was inaugurated in March 2007, due to the need to increase the computing capacity that serves the scientific community. As a result of this need, an update of the MareNostrum supercomputer was carried out , in which the JS20 blades were replaced with JS21 blades, both from IBM, thus doubling their computing capacity. The substituted blades were used to create a distributed structure of Supercomputers in different locations of the Spanish geography.
Half of said blades was used to expand Magerit, the supercomputer belonging to CeSViMa (UPM). The rest was distributed, in equal parts, to create the nodes of the universities of Cantabria, Malaga, Valencia, Zaragoza and the Institute of Astrophysics of the Canary Islands (IAC). In this way, the RES is formed by the following supercomputers:
Subsequently, Atlante , at the Technological Institute of the Canary Islands and MinoTauro , would join a system with GPUs in the BSC. Currently, the extended RES is a Singular Technical Scientific Infrastructure ( ICTS ) distributed. The updated information of its members and capacities can be consulted in the following link .
In the Universitat de València, the machine is called Tirant, in honor of the protagonist of the Valencian novel Tirant lo blanc , written by Joanot Martorell in 1490.
In November 2012, MareNostrum suffers a second update, becoming a system of 1 PFlop / s (1 Peta Flop). As a consequence, all the nodes of the RES are updated and Tirant has a configuration of 2048 PowerPC 970+ cores and 4 TB of distributed RAM, with a peak power of 18.8 TFlops / s.
In July 2017, MareNostrum is updated again and now has 11 PFlop / s, so in July 2018, after some updating works of the Burjassot Data Processing Center, Tirant v3 starts up .
The new system consists of 336 nodes, each with two Intel Xeon SandyBridge E5-2670 processors at 2.6 Ghz and 32 GB DDR3 RAM (5376 cores). This gives the new Tirant 111.8 Tflop / s of performance and 10 TB of distributed memory. For the first time, Tirant mounts a storage system based on Luster, which provides 283 TB, enough for the storage needs of most users.
These supercomputers are accessible by any researcher, distributing the calculation time between the RES, which in the case of Tirant has 50%, and the institution that receives it, which has the remaining 50%.
In principle, any researcher from the Valencian Community can make a request for calculation hours for 50% of Tirant. In addition, they can request time of 50% assigned to the RES, following the forms collected on the web of the RES in the BSC.
Once the request for calculation hours has been completed and sent, it will be evaluated by a committee of 5 scientists who will determine whether or not their project can be executed on the machine of the Spanish Supercomputing Network, Tirant . For this, the following criteria will be used:
Access to the service is managed through an Access Committee, composed of scientists responsible for assessing each of the access requests and planning access to available resources. The resources are assigned for a period of 4 months, after which it is necessary to submit a new access request. The chosen model mimics the one that currently exists in the BSC, which has amply demonstrated its validity. The opening and completion of the deadlines for submitting applications will be duly published both on the Tirant website and on the scientific calculation users of the UV.
To make the calculation hours request, you must fill in the model that corresponds to your needs. There are two models available: calculation time request for a new project or request for continuation of an existing project, which for any reason needs more calculation hours.
The forms are PDF files that must be completed. We recommend that Acroread be used. Once all is filled out, you must send it attached by mail to tirant@uv.es or follow the Acroread instructions after "Send form". Remember that there are two versions, one for new projects and another to request a renewal of a currently approved project.
The Universitat de València allows guided visits to the installations of the Tirant supercomputer. The visit allows to know better the Spanish Network of Supercomputing and the operation of the node of Valencia.
Due to the recent construction of the new Data Processing Center (CPD) of the Universitat de València, the Tirant supercomputer has been moved to a new location, which forces us to make some changes in the visits. Please, although you have already come other times, review the new requirements.
The visit lasts approximately 1 hour and 30 minutes and consists of two parts, an introductory talk and a physical visit to the CPD. Consider the following:
