Hi,
 
I have a desktop with AMD 1950X processor (16 cores and 32 thread). When I ran cado-nfs to factor large number (c.195), I got the following error:
 
Error:Polynomial Selection (size optimized): Exceeded maximum number of timed out workunits, maxtimedout=100 
Traceback (most recent call last):
  File "./cado-nfs.py", line 122, in <module>
    factors = factorjob.run()
  File "./scripts/cadofactor/cadotask.py", line 5429, in run
    last_status, last_task = self.run_next_task()
  File "./scripts/cadofactor/cadotask.py", line 5504, in run_next_task
    return [task.run(), task.title]

    self.cancel_wu(entry["wuid"], commit=False)
  File "./scripts/cadofactor/cadotask.py", line 1497, in cancel_wu
    raise Exception("Too many timed out work units. Please increase tasks.maxtimedout (current value is %d)" % maxtimedout)
Exception: Too many timed out work units. Please increase tasks.maxtimedout (current value is 100)
 
 
I increased the "tasks.maxtimedout" in c.195 from 100 to 1000, however I got the same error.
 
Can anyone help me with that?
 
Regards,
Sara
