Concurrency Support ?

Hi,

I was wondering if a fanJ object could be used concurrently by
multiple threads. e.g. : Can we run it simultaneously on multiple
inputs ? Does it has the proper Readers / Writer Lock allowing it to
be evolved while other thread run commands on it ?

Thanks,

Gabriel

Nope.

According to http://leenissen.dk/fann/forum/viewtopic.php?t=149, FANN is not thread safe. FannJ is a simple java wrapper around this library and provides no extra concurrency support.

Ok. Thanks. I stumbled upon that link while doing some research too
but I was wondering if this applied only for weights changes and not
to simple evaluation since it it should normally be only reading the
inner fields of fann.

I guess fann must be using some kind of internal intermediary data to
perform its evaluations.
