Dear Ray developers,
I am trying to do a denovo assembly using Ray with 300bp paired end reads.
But I am receiving an error halfway of the run with the following command:
mpiexec -n 28 /home/programs/assembly/Ray-2.3.1/Ray -k 101 -p read1.fastq
read2.fastq -o k_101
Using different k-mers doesn't help.
Critical exception: The length of the requested memory exceeds the
CHUNK_SIZE: 63958792 > 33554432
Ray: RayPlatform/memory/MyAllocator.cpp:97: void*
MyAllocator::allocate(int): Assertion `false' failed.

Any idea what might be causing the problem?
Thanks in advance,
