<br><font size=2 face="sans-serif">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 size=2 face="sans-serif">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 size=2 face="sans-serif">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>
