    CAM6 with SE dynamical core performance decrease from Cheyenne to Derecho

    Hi Derecho / Cheyenne / CESM users, I am planning to run some simulations but realised while setting up and running some test simulations that there is a performance issue that seems to occur using Derecho. A strong decrease in the performance is visible an I/we do not understand why this...

    performance on AMD EPYC cluster

    Hello, I'm in the process of porting CESM2 to the new Dutch supercomputer Snellius, which is comprised of AMD EPYC 7H12 processors. Each node has 2 CPU's with 64 cores each, making 128 cores per node in total. Nodes are tied together with Infiniband HDR100 (100Gbps), fat tree topology. So far...

    Is there any optimized Cam in ARMV8 machine?

    I want to running CESM in my ARMV8 machine, but find out that the performance is not good enough, The major time consumption stays at mapz_module and clubb_intr inside Cam, can anyone provide an optimized version?

    Viability of running CESM on 40 cores

    We have a cluster with relatively slow interconnect between nodes, its geared to high thru-put not HPC. We would welcome guidance: are we overoptimistic if we seek to run say 2 degree by 2 degree CESM on just one node with spec: 768Gb 40core Intel(R) Xeon(R) Gold 6138 CPU @ 2.00GHz nodes with...
