Hi, 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: Fatal error in PMPI_Scatter: Message truncated, MPIDI_CH3U_Receive_data_found(131) Message from rank 0 and tag 5 truncated. 1774000 bytes received but buffer size is 52. MPIC_Send(59).......: Negative count, value is -32 I cannot understand how does this happened. the hello world is tested for network link. and the program is fine running on one computer. Thank you very much for any suggestions -- Best Regards, Sufeng Niu ECASP lab, ECE department, Illinois Institute of Technology Tel: 312-731-7219
