Hi Vladimir –
For node naming, there’s a decent explanation on the “slurm.conf” man page: Multiple node names may be comma separated (e.g. "alpha,beta,gamma") and/or a simple node range expression may optionally be used to specify numeric ranges of nodes to avoid building a configuration file with large numbers of entries. The node range expression can contain one pair of square brackets with a sequence of comma separated numbers and/or ranges of numbers separated by a "-" (e.g. "linux[0-64,128]", or "lx[15,18,32-33]"). Note that the numeric ranges can include one or more leading zeros to indicate the numeric portion has a fixed number of digits (e.g. "linux[0000-1023]"). Up to two numeric ranges can be included in the expression (e.g. "rack[0-63]_blade[0-41]"). If one or more numeric expressions are included, one of them must be at the end of the name (e.g. "unit[0-31]rack" is invalid), but arbitrary names can always be used in a comma separated list. via http://slurm.schedmd.com/slurm.conf.html And for SLURM_TASKS_PER_NODE: Number of tasks to be initiated on each node. Values are comma separated and in the same order as SLURM_NODELIST. If two or more consecutive nodes are to have the same task count, that count is followed by "(x#)" where "#" is the repetition count. For example, "SLURM_TASKS_PER_NODE=2(x3),1" indicates that the first three nodes will each execute three tasks and the fourth node will execute one task. via http://slurm.schedmd.com/srun.html Best of luck, -- Ed Swindelles Manager of Advanced Computing University of Connecticut From: Kolodiev, Vladimir [mailto:[email protected]] Sent: Friday, July 29, 2016 5:16 AM To: slurm-dev <[email protected]> Cc: Yakovlev, Sergey <[email protected]>; Lobanov, Andrey <[email protected]> Subject: [slurm-dev] A question about SLURM environment Hello, I am Vladimir Kolodiev, a SW engineer from Intel Corp. I work with SLURM now and I have a question about SLERM_STEP_NODELIST and SLURM_TASKS_PER_NODE formats. I understood that their formats are “hostA[1-18,22],hostB,hostC[001-123]“ and “2,4,6(x19)”, but I did not find documentation describing this. Can you please point out where they are documented?
