Hello, I would like to use hwloc_distrib for a project, but I'm having some trouble understanding how it distributes. Specifically, it seems to avoid distributing multiple processes across cores, and I'm not sure why.
As an example, consider the actual output of: $ hwloc-distrib -i "4 4" 2 0x0000000f 0x000000f0 I'm expecting hwloc-distrib to tell me how to distribute 2 processes across the 16 PUs (4 cores by 4 PUs), but the answer only involves 8 PUs, leaving the other 8 unused. If there were more cores on the machine, then potentially the vast majority of them would be unused. In other words, I might expect the output to use all of the PUs across cores, for example: $ hwloc-distrib -i "4 4" 2 0x000000ff 0x0000ff00 Why does hwloc-distrib leave PUs unused? I'm using hwloc-1.9. Any help in understanding where I'm going wrong is greatly appreciated! Thanks, Tim
