Subject: [Bug c++/42194] performance degradation with STL complex convolution operation
Date: Sun, 10 Jan 2010 05:54:00 -0000 [thread overview]
Message-ID: <20100110055444.23933.qmail@sourceware.org> (raw)
In-Reply-To: <bug-42194-18494@http.gcc.gnu.org/bugzilla/>
------- Comment #3 from jagjeet dot nain at gmail dot com 2010-01-10 05:54 -------
Got the speedup improvement with fcx-limited-range flag.
but got into another problem.
This particular code when run on Sunx4100 server(with OpenSuse 10.1) shows
unusual behavior. Different runs have different runtime. always no other load
on server was ensured.
One in three runs have double runtime of normal run.
Processor is dual core AMD opteron.
any help in this matter is appreciated.
