QPSMPGP has too verbose output

[haplav]

It monitors convergence although it's not asked to do so - prints lines like

180 MPGP [c] ||gp||=9.9891341100e-09,	||phi||=9.9891341100e-09,	||beta||=0.0000000000e+00,	alpha=1.2017124429e-01

What code is that in and what is the output with -options_view?
This should be printed only when you pass -qps_monitor true or set the default monitor by QPSMonitorSet(qps,QPSMonitorDefault,NULL,0)

• https://github.com/permon/permon/blob/master/src/tutorials/output/jbearing2_4.out

There is no -qps_monitor true. That's my point.

[jkruzik]

That is due to an explicit QPSMonitorSet in

permon/src/tutorials/jbearing2.c

Line 531 in 19a72fa

ierr = QPSMonitorSet(qps,QPSMonitorDefault,NULL,0);CHKERRQ(ierr);

You should be able to cancel it with -qps_monitor_cancel but even though it is in the docs, it is missing in QPSSetFromOptions().

I would keep it the jbearing2 tutorial (it is an example how to use QPSMonitorSet, and provides us with a warning if MPRGP takes a different step).

OK, I haven't anticipated nor noticed there's implicit QPSMonitorSet(). Fair enough.

You should be able to cancel it with -qps_monitor_cancel but even though it is in the docs, it is missing in QPSSetFromOptions().

OK, this is an issue but separate from this one.

So this is not relevant, closing.
