Assumes that all processors in a communicator either Many br1) have a common /tmp or Many br2) each has a separate /tmp Many breventually we can write a fancier one that determines which processors Many brshare a common /tmp. Many br
This will be very slow on runs with a large number of processors since Many brit requires O(p*p) file opens. Many br
If the environmental variable PETSC_TMP is set it will use this directory Many bras the "/tmp" directory. Many br
