Hi!<div>I have two computer in the MPI program, and I use the function mpi_barrier(MPI_COMM_WORLD) to synchronize the two process on the two computer.</div><div>One of the process is running more slower than the other one because two different GPUs is on the two computer. I got "fatal error in PMPI_Barrier" and "connect failed--the semaphore timeout period has expired".</div><div>Is there a time limitation in the mpi_barrier()?<br><br><div>--<br><p><span style="font-size: 14px; "><font class="Apple-style-span" face="'Times New Roman'">Email: </font><a href="mailto:yogikai@163.com"><font class="Apple-style-span" face="'Times New Roman'">yogikai@163.com</font></a><font class="Apple-style-span" face="'Times New Roman'"><br>Address: Room 921, Automation Building,<br>No. 95 Zhongguancun East Road,<br>Haidian District, Beijing 100190, China<br>Cell Phone:15210370340<br></font><span class="Apple-style-span" style="line-height: 15px; color: rgb(42, 42, 42); ">
