I have run sendrecv function in Pallas but it failed to run it. Here is
the output

These errors are coming from the collective routines, not the PML/BTL
layers. It looks like the reduction codes are trying to call malloc
(0), which doesn't work so well. We'll take a look as soon as we
can. In the mean time, can you just not run the tests that call the
reduction collectives?
