Hydra issue during MPI_Finalize
by Kiryanov, Yury 16 Aug '12

16 Aug '12

Hello, We run into an issue into Hydra code. Deadlock occurs when pmi_proxy is waiting for child (MPI) process termination and MPI process sent the "finalize" message and waiting for "finalize_ack" response from pmi_proxy. The root case is in blocked waitpid(-1, &ret_status, 0) into pmip.c. Looks like it should be waitpid(-1, &ret_status, WNOHANG). -- Best regards, Yury Kiryanov i-net : 8312-2043 e-mail: yury.kiryanov(a)intel.com<mailto:[email protected]> -------------------------------------------------------------------- Closed Joint Stock Company Intel A/O Registered legal address: Krylatsky Hills Business Park, 17 Krylatskaya Str., Bldg 4, Moscow 121614, Russian Federation This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

Hello, Please be informed that there is a bug related to COMM_OVERRIDES in MPID_Iprobe implementation. NULL check is performed for probe function, while iprobe function is called after that: if (vc->comm_ops && vc->comm_ops->probe) { mpi_errno = vc->comm_ops->iprobe(vc, source, tag, comm, context_offset, &found, status); //WBR, Mikhail Brinskiy -------------------------------------------------------------------- Closed Joint Stock Company Intel A/O Registered legal address: Krylatsky Hills Business Park, 17 Krylatskaya Str., Bldg 4, Moscow 121614, Russian Federation This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
