Hi Rajesh,
You're right, bpipe can only open one connection at a time. However, you can use the function multiple times to set up multiple connections. Instead of a single function call to create multiple connections, you would have to call bpipe each time you want to open a connection. The function returns a connection object.
For example:
% for all servers
for i = 1:numServers
% open a connection and store the connection object in a cell array
c{i} = bpipe(...);
end
Once you're done, you'll have to close all the connections the same way:
for i = 1:numServers
% close the connection
close(c{i})
end
