SOAPdenovo2 long run

[Phoenix]

Hello all,
I’m trying to assemble a plant genome (this is my first time). I have 100bp PE reads (106G forward and 106G reverse). I’m using soapdenovo2 to assemble the data on a cluster. The job was running on 10 nodes with each using 20 threads and 80Gb of memory. The maximum amount of time allowed for a job is 7 days.
I tried the following script however the job does not finish in the allotted time
SOAPdenovo-63mer all -s ./soap.config -K 63 -R -o genome

So then I tried to build it in parts using the script below, but even this does not finish
SOAPdenovo-63mer pregraph -s ./soap.config -K 63 -R -o genome

If using more computer resources or getting my time limit extended is not an option, how can I assemble the genome?

I tried using DMTCP to checkpoint the run so that I can resubmit the run and continue the assembly after the 7 days but I cannot get DMTCP to work with soapdenovo2.

I would be grateful for any assistance
Cheers

I'd try a speedy assembler like BBtools tadpole.sh as a first pass just to see what a rough draft looks like. A slower assembler but one that should finish in a day is abyss-pe with the bloom filter option enabled.

Thanks for the suggestions. I'll give these tools a try
