[Jlab-scicomp-briefs] New farm14 nodes adding ~2500 cores

[Sandy Philpott]

JLab Scientific Computing Users, 

The 104 new Physics nodes for the data analysis farm cluster have just arrived (well, except their power cords, coming tomorrow). These farm14* nodes are dual Intel E5-2670v3 (Haswell) 12 core, 2.3 GHz, with 32 GB DDR4-2133 memory -- the leanest memory configuration in the farm (less than 1 GB per job slot on serial jobs). They will run with as many slots as experience shows they can handle, based upon statistical measurements in actual running. Their network includes 20 gigabit Infiniband DDR for I/O to the Lustre and ZFS filesystems. Their initial installation in the F112 Data Center begins this week. 


This farm node installation will add a total of 104 * 24 = 2496 cores to the existing 1400 core farm. We will be working with early users to identify the correct operating system and kernel to install, then move the systems to production mode as their burn-in proves successful. More details to follow. 


Regards, 
Sandy
