[mpich-discuss] MPI_Send MPI_recv

[Lu, Huiwei]

Hi, Chen,

Read the source code. It’s not about redundancy. You have to invest your time on it to understand all the details. To help you start with, you can read section 4 “Architecture of MPICH” of paper “A High-Performance, Portable Implementation of the MPI Message Passing Interface Standard”. It helps you understand the overall architecture of MPICH better.

p.s. It’s an English list. You may want to asking questions in English only.

Best,

> Hi! Who has done the work of implementing some part of MPI standard by himself or herself? I need the source code on the mechanism of sending and receiving data of MPI_Send and MPI_Recv. Just the standard mode of blocking communication is OK, and the error checking part is not necessary and I do not need it. I cannot understand the code of MPICH very well as there is much redundancy and I work on hardware and do not know much about C/C++. Could you please provide me with some code or materials? Many thanks!
