After reading the code, every mailbox should be 4096 byte size. And the total mailbox size is host * 4096. Ony one host is here, so the total mailbox size here is 4096. why should the 'dd' operation read 1024000 byte which is 1000K byte much lager than 4096 here?
The controlling parameter is MAX_HOST_ID=250, not the number of current cluster members.
I am wondering if we can do some optimization here, like to read and write the block size linear to the current cluster members.
