Sylvain Jeaugey 57368189e1 Remove error logging from a normal path
When initNet fails, we should not print the backtrace as it is
supposed to be normal operation (falling back to sockets)
2018-12-04 14:47:41 -08:00
Sylvain Jeaugey 4b39a4cf91 Fix GPU Direct RDMA detection.
Whether the network supported GPU Direct RDMA or not was ignored,
causing sockets to break when cards were local enough that NCCL
tried to use it.

Sylvain Jeaugey eed8218e17 Rework shared memory code to use SYSCHECK macros.
This is to handle EINTR/EGAIN properly (issue #137), and also
make the code consistent with the rest.

Unfortunately posix_fallocate and mmap do not follow the classic
return code/errno pattern, so we need to write wrappers around those
functions.
2018-11-29 12:52:13 -08:00
Sylvain Jeaugey 302d538b73 Rework SYSCHECK macros to better handle retries.
SYSCHECKVAL was not retrying when a retry was needed. Since not all
calls are inside a loop, that means we could silently miss an
EINTR/EAGAIN return code.

Also rework the socket connection code and improve error reporting.
