[gmx-users] new i9 processor

[Harry Mark Greenblatt]

BS”D

Dear All,

  The new Skylake-X CPU’s have very high core counts, and could, in theory, take the place of a two socket 16 core Xeon system.  One could create a machine as follows:

1 x Core i9 7960X with 16 cores
2 x Geforce 1080 graphic cards,

and run a simulation with 2 MPI ranks, coupling 8 cores to 1 gpu per rank.

Would there be any technical problems arising from the single socket configuration, as opposed to a dual socket Xeon setup?  Any issues if a 14 core processor was used (7 cores per rank, i.e., an odd number)?

Thanks

Harry
