Description Doug Jacobsen 2017-10-02 11:07:20 MDT

Hello,

<meta>This bug is the lowest possible sev4 available</meta>

We have a user that wants to enumerate many KNL nodes using syntax like:
nid01234*16
nid01235*16

and so on.

The user gets this _exact_ error string:

srun: error: Hostlist is too long for the allocate RPC!

Reviewing api/allocate.c slurm_read_hostfile(), this appears to be because it allocates a buffer 1024 bytes longer than the length of the file.  This essentially make the more compact syntax unworkable for larger allocations.

We reviewed bug 4169 in preparing this bug =)

Thanks,
Doug

Hi Doug,

I'm working on bug 4169 right now, and my fix should also fix this bug. Keep tabs on bug 4169. I'll mark this one as a duplicate of 4169 (I realize it's not the exact same problem, but the patch will fix both problems).

Marshall
