Can you also send the output of: /usr/local/my-mpich-3.2/64bit/bin/mpichversion /usr/local/my-mpich-3.2/64bit/bin/mpiexec -info Something in your error output doesn't look right to me. I'm having a hard time finding the code that would execute a PMI command that causes the string buffer to overflow and omit a newline. Ken On 07/26/2016 11:25 AM, Gajbe, Manisha wrote:
Hi Kenneth,
The configure script is default except the "prefix". I used Intel compilers version 16.0.2.
$ ./configure --prefix=/usr/local/my-mpich-3.2/64bit
Hi Halim,
I removed all the writes to stdout. No change in the output. Also, the code runs with IntelMPI 5.1.3 without any issues with lots of writes to stdout. Do you have any suggestion on setting up the limits of pipe on what should be the reasonable size.
Below is output from my ulimit
[mmgajbe@fm05wcon0025 Test]$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 62912 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 2048 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 4096 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
Hi Husen,
I tried on multiple systems with different Oss such as RHEL 7.0, OpenSuse, Ubuntu 12.04 etc. However, the error is observed only with MPICH and not with IntelMPI.

it seems the number of processes that can be created in one machine limited by Operating System.

Hi,
I have installed mpich-3.2 on a multicore platform. When I spawn 272 processes , I get the error message mentioned below. I am able to create upto 271 processes successfully.
