[mvapich-discuss] mvapich2 1.4.0 and MPI_Comm_Spawn fatal errors

[Bernd Kallies]

Dear mvapich2 dev team,

I'm currently playing with dynamic process creation with mvapich2 1.4.0.

Note that there is a funny bug in
src/mpid/ch3/src/ch3u_comm_spawn_multiple.c line 195:

if (mpi_errno != PMI_SUCCESS) {

must read

if (pmi_errno != PMI_SUCCESS) {

otherwise fatal spawn errors cannot be handled correctly, when using
pmi.

My question: will you fix this in the mpich2 sources distributed with
mvapich2, or will you update to a more recent mpich2?

Sincerely, BK
