MPI_Waitany: "The semaphore timeout period hasexpired. ( errno
121)"<BR></FONT><BR></DIV>
<DIV></DIV><BR><FONT face=sans-serif size=2>I am encountering the following
error at runtime when using MPI_Waitany:</FONT> <BR><BR><FONT size=3><B>"The
semaphore timeout period has expired. ( errno 121</B>)"</FONT> <BR><BR><FONT
face=sans-serif size=2>It looks like it's occuring in MPIDU_Sock_wait around
line 2603. Can I get more information on this error somewhere? Is
there a way to increase this "timeout period"?</FONT> <BR><BR><FONT
face=sans-serif size=2>On a separate note, is there a proper way to implement a
"dynamic network" using MPI, ie. a network in which nodes are added or
subtracted during runtime? Can someone recommend a good document or method
for that?</FONT> <BR><BR><FONT face=sans-serif size=2>Thank you and
