Hello Pier-luc,
Normally, when I run the script I get more then one core
running. But, currently only one core is running at a
time causing the error. Its not threading correctly for
some reason now.
1) Ray-v2.2.0/
2) a.Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-48-generic
x86_64)
b.server AMD opteron 2.0ghz (16cores) 128GB RAM
3) Tested it with a 12 mb (100k reads) and 4 gb (10m
reads).
Ray was running perfectly fine then it just stopped all
the sudden and had the first error
Ray: error while loading shared libraries:
libmpichcxx.so.1.2: cannot open shared object file: No such
file or directory
I removed everything then reinstalled
sudo apt-get install libcr-dev mpich2
Tried old and new mpi
1.4.3 by sudo apt-get install openmpi-bin openmpi-doc
libopenmpi-dev
1.5.3 by sudo apt-get install -y autotools-dev g++
build-essential openmpi1.5-bin openmpi1.5-doc
libopenmpi1.5-dev
Reinstalled Ray-v2.2.0
make PREFIX=/usr/local/bin/ray-build
Now nothing works with another error:
Critical exception: The system is out of memory, returned
NULL.
Requested -54534904 bytes of type RAY_MALLOC_TYPE_BLOOM_FILTER
HELP!
