[Cado-nfs-discuss] DLP: Required qmin not found

Hi Lao,

There has been some change that now imposes that a parameter tasks.qmin
be present in the param files, but somehow the params.p155 file was not
modified accordingly. Thanks for reporting.

This can be fixed by adding the following line to the parameter file:
  tasks.qmin = 15000000
(and I will commit the change to the repo)

Regards,
Pierrick
