### Login Nodes
*One old login node* (``merlin-l-01.psi.ch``) is inherit from the previous Merlin5 cluster. Its mainly use is for running some BIO services (`cryosparc`) and for submitting jobs.
*Two new login nodes* (``merlin-l-001.psi.ch``,``merlin-l-002.psi.ch``) with similar configuration to the Merlin6 computing nodes are available for the users. The mainly use
is for compiling software and submitting jobs.
Two login nodes (`merlin-l-001.psi.ch`, `merlin-l-002.psi.ch`) are available to users. They are configured similarly to the Merlin6 compute nodes and are intended primarily for software compilation, job submission, lightweight preprocessing, and visualization tasks.
The connectivity is based on **ConnectX-5 EDR-100Gbps** for the new login nodes, and **ConnectIB FDR-56Gbps** for the old one.
Each login node is equipped with an NVIDIA Quadro P2000 GPU. These GPUs are not intended for large-scale or long-running compute workloads,
but rather to support interactive and lightweight GPU-accelerated tasks such as OpenGL-based visualization, remote desktop sessions,
debugging, testing GPU-enabled applications, and validating CUDA or graphics workflows before running them at scale on the compute nodes.
This allows users to develop and debug GPU-aware software without consuming compute-partition resources, while still keeping heavy production workloads confined to the batch system.
The connectivity is based on **ConnectX-5 EDR-100Gbps**.
