More detailed command to try:
*#PBS -N LargeJob3
#PBS -o LargeJob3.stdout
#PBS -e LargeJob3.stderr
#PBS -l walltime=120:00:00
#PBS -l nodes=100
module load openmpi_gcc64/1.4.3_ofed
mpiexec -n 1024 \
Ray -k 23 -o **LargeJob3**\

-p mates11.fastq mates11.fastq \
-p mates21.fastq mates21.fastq *
100 nodes is a lot. It will give you collectively
100*32 giga-bytes of memory, or 3.2 tera-bytes.
This will use a de Bruijn graph of degree 32 for the communication.
This will reduce memory usage by Open-MPI and will also reduces a lot
the latency to something
near
mpiexec will allocate nodes with a round-robin policy by default I think.

120hours walltime is not enough

#PBS -l nodes=100

Yes, it does that.
There will be binary files with the ".ray" extension in the
directory where you launched Ray.
You can not change the k-mer length when starting from old checkpoints.
The command needs to have the same number of arguments in the same order.
On what kind of dataset are you exceeding time limits ?

I saw these options on Ray
Checkpointing
-write-checkpoints
Write checkpoint files
-read-checkpoints
Read checkpoint files
-read-write-checkpoints
Read and write checkpoint files
I'm hitting walltimes on the cluster I'm using and I'm wondering if by
setting:
-read-write-checkpoints
I can resume where Ray got killed because of walltime?
If that's the purpose, what a great feature! :-)
