Hi all,<div><br></div><div>I'm testing the message passing interface of the SCC and I see a lot of buffer overflows. The test program is very easy as it spawns 2 instances, one in core 0, the other in core 1. Core 1 is continuously sending messages to core 0. It's using the continuation closure so there is a control flow, at least in the x86_64.</div>
<div><br></div><div>But running it on the SCC I get this message:</div><div><br></div><div><div>kernel 0: idctest: RCK message buffer overflow</div><div><br></div><div>So I guess the control flow is not working properly... as the sending of messages is working much faster than the receiving ones...</div>
<div><br></div><div>I attach the example,</div><div><br></div><div>Thanks,</div><div><br></div>-- <br>Zeus Gómez Marmolejo<br>Barcelona Supercomputing Center<br>PhD student<br><a href="http://www.bsc.es" target="_blank">http://www.bsc.es</a><br>
