New CÉCI infrastructure status page
In order to optimize the communication of small downtimes or degraded service periods, we have setup a "status" page that will list the current known issues on the CÉCI infrastructure. Users are invited to refer to that page in case they face some issue on the infrastructure. This page will allow reducing the number of emails sent to the mailing list when the message is not relevant for all CÉCI users.
The link is in the top banner of the website, between "Documentation" and "Support".

LUMI Training - Practical course on the CUDA to HIP porting
CSC and the LUMI User Support Team organize their first training day that will focus on porting CUDA applications to HIP. This training aims to help the users to port their code to LUMI, the European pre-exascale supercomputer, that will achieve its high computing power thanks to a large number of nodes with AMD GPUs. This event will take place on February 26.
This session will provide an extensive dive into the Hipify tools, many examples and a hands-on session. If you’re developing your code with CUDA and wish to harness the computing power of LUMI in the future this training is a fantastic opportunity.
You can find further details and the registration form here.

Survey on Big Data and Machine Learning needs
We are conducting a survey about current and future High Performance Data Analysis (HPDA) works & needs, covering BigData, DeepLearning, MachineLearning, AI & co. Research groups already active in those fields are our primary center of interest. However, those moving or intending to move into those fields are welcome to fill the survey too. Our objective is to identify concrete hardware and software requirements for the future CECI Vega2 cluster which will be oriented towards HTC (High Throughput Computing) and HPDA.
You are therefore cordially invited to follow this link and fill the survey.
