<div dir="ltr">Hi,<div><br></div><div>I apologize to post so many questions, but I got a new question here: my program runs everything well on 1 machine right now. when I run it on two machines, the program got error:</div>
<div><br></div><div>Fatal error in PMPI_Scatter: Message truncated,</div><div>MPIDI_CH3U_Receive_data_found(131) Message from rank 0 and tag 5 truncated. 1774000 bytes received but buffer size is 52.</div><div>MPIC_Send(59).......: Negative count, value is -32</div>
<div><br></div><div>I cannot understand how does this happened. the hello world is tested for network link. and the program is fine running on one computer.</div><div><br></div><div>Thank you very much for any suggestions</div>
