Heterogeneous computing at INFN-T1

At INFN-T1 we recently acquired some nodes with ARM and RISC-V CPUs to understand the experiment level of readiness on new hardware solutions and to test our production pipelines. After some initial testing, ARM resources entered the standard farm, since the stability both of the nodes and of the software was production quality ready. On the contrary RISC-V solutions are still to be considered only as testbed, since the software is not ready for general production. In this article we will describe all the activities that were necessary to enable users to run on ARM and RISC-V and will give some figures on performance, compared to x86_64 counterpart. In the end we will try to describe our point of view for the possible mass adoption of this architecture in Tier1 data centers.
