Introduction
The mpiblast module must be manually loaded before submitting any mpiblast jobs. Two examples below demonstrate how to setup and submit jobs to the mpi queue.
Version Selection
All Clusters (except Guppy)
module unload openmpi intel module load intel/12.1.3 openmpi/intel/1.6.2 mpiblast/1.6.0
Guppy Only
module unload openmpi intel module load intel/11.0.083 openmpi/intel/1.4.2 mpiblast/1.6.0
Job Submission
sqsub -r 15m -n 24 -q mpi --mpp=3g -o ofile%J mpiblast etc
where the number of cores n=24 is arbitrary.
Example Jobs
DROSOPH
Copy sample problem files (fasta database and input) from the /opt/sharcnet examples directory a directory under work as shown here. The fasta database used in this example can be obtained as a guest from NCBI here http://www.ncbi.nlm.nih.gov/guide/all/#downloads_ then clicking "FTP: FASTA BLAST Databases".
mkdir -p /work/$USER/samples/mpiblast/test1 rm /work/$USER/samples/mpiblast/test1/* cd /work/$USER/samples/mpiblast/test1 cp /opt/sharcnet/mpiblast/1.6.0/examples/drosoph.in drosoph.in gunzip -c /opt/sharcnet/mpiblast/1.6.0/examples/drosoph.nt.gz > drosoph.nt.$USER
Create a hidden configuration file using a text editor (such as vi) to define a Shared storage location between nodes and a Local storage directory available on each compute node as follows:
[roberpj@hnd20:/work/$USER/samples/mpiblast/test1] vi .ncbirc [NCBI] Data=/opt/sharcnet/mpiblast/1.6.0/ncbi/data [BLAST] BLASTDB=/scratch/YourSharcnetUsername/mpiblasttest1 BLASTMAT=/work/YourSharcnetUsername/samples/mpiblast/test1 [mpiBLAST] Shared=/scratch/YourSharcnetUsername/mpiblasttest1 Local=/tmp
Partition the database into 8 fragments into /scratch/$USER/mpiblasttest1 where they will be searched for when running a job in queue according to the .ncbirc file:
module load mpiblast/1.6.0 mkdir /scratch/roberpj/mpiblasttest1 rm -f /scratch/$USER/mpiblasttest1/* cd /work/$USER/samples/mpiblast/test1 [roberpj@hnd20:/work/$USER/samples/mpiblast/test1] mpiformatdb -N 8 -i drosoph.nt.$USER -o T -p F -n /scratch/$USER/mpiblasttest1 Reading input file Done, read 1534943 lines Breaking drosoph.nt into 8 fragments Executing: formatdb -p F -i drosoph.nt -N 8 -n /scratch/roberpj/mpiblasttest1/drosoph.nt -o T Created 8 fragments. <<< Please make sure the formatted database fragments are placed in /scratch/roberpj/mpiblasttest1/ before executing mpiblast. >>> [roberpj@hnd20:/scratch/roberpj/mpiblasttest1] ls drosoph.nt.000.nhr drosoph.nt.002.nin drosoph.nt.004.nnd drosoph.nt.006.nni drosoph.nt.000.nin drosoph.nt.002.nnd drosoph.nt.004.nni drosoph.nt.006.nsd drosoph.nt.000.nnd drosoph.nt.002.nni drosoph.nt.004.nsd drosoph.nt.006.nsi drosoph.nt.000.nni drosoph.nt.002.nsd drosoph.nt.004.nsi drosoph.nt.006.nsq drosoph.nt.000.nsd drosoph.nt.002.nsi drosoph.nt.004.nsq drosoph.nt.007.nhr drosoph.nt.000.nsi drosoph.nt.002.nsq drosoph.nt.005.nhr drosoph.nt.007.nin drosoph.nt.000.nsq drosoph.nt.003.nhr drosoph.nt.005.nin drosoph.nt.007.nnd drosoph.nt.001.nhr drosoph.nt.003.nin drosoph.nt.005.nnd drosoph.nt.007.nni drosoph.nt.001.nin drosoph.nt.003.nnd drosoph.nt.005.nni drosoph.nt.007.nsd drosoph.nt.001.nnd drosoph.nt.003.nni drosoph.nt.005.nsd drosoph.nt.007.nsi drosoph.nt.001.nni drosoph.nt.003.nsd drosoph.nt.005.nsi drosoph.nt.007.nsq drosoph.nt.001.nsd drosoph.nt.003.nsi drosoph.nt.005.nsq drosoph.nt.dbs drosoph.nt.001.nsi drosoph.nt.003.nsq drosoph.nt.006.nhr drosoph.nt.mbf drosoph.nt.001.nsq drosoph.nt.004.nhr drosoph.nt.006.nin drosoph.nt.nal drosoph.nt.002.nhr drosoph.nt.004.nin drosoph.nt.006.nnd
Submit a short job with a 15m time limit on n=16 cores calculate by taking N=8 fragments + 8. If all goes well output results will be written to drosoph.out and the execution time will appear in ofile%J where %J is the job number:
[roberpj@hnd20:/work/$USER/samples/mpiblast/test1] sqsub -r 15m -n 106 -q mpi --mpp=1G -o ofile%J mpiblast -d drosoph.nt.$USER -i drosoph.in -p blastn -o drosoph.out --use-parallel-write --use-virtual-frags submitted as jobid 6966896 [roberpj@hnd20:/work/roberpj/samples/mpiblast/test1] cat ofile6966896.hnd50 Total Execution Time: 1.80031
When submitting a mpiblast job on a cluster such as goblin that doesnt have an inifiniband interconnect better performance (at least double speedup) will be achieved running the mpi job on one compute node. For regular users of non-contributed hardware typically specify "-n 8" to reflect the max number of cores on a single node:
sqsub -r 15m -n 8 -N 1 -q mpi --mpp=4G -o ofile%J mpiblast -d drosoph.nt -i drosoph.in -p blastn -o drosoph.out --use-parallel-write --use-virtual-frags
Sample output results computed previously with BLASTN 2.2.15 [Oct-15-2006] are included in /opt/sharcnet/mpiblast/1.6.0/examples/ROSOPH.out to compare your newly generated drosoph.out file with.
UNIGENE
The main purpose of this example is to illustrate some additional options and switchs that maybe useful for debugging and for dealing with larger databases as described in official detail at http://www.mpiblast.org/Docs/Guide. The fasta database used in this example can also be downloaded from http://www.ncbi.nlm.nih.gov/guide/all/#downloads_ as a guest by clicking "FTP: UniGene" then entering the "Homo_sapiens" sub-directory. More information about UniGene alignments can be found at https://cgwb.nci.nih.gov/cgi-bin/hgTrackUi?hgsid=95443&c=chr1&g=uniGene_3 . As with Example1 above, for convenience all required files can simply be copied from the /opt/sharcnet examples subdirectory to work as shown here:
mkdir /work/$USER/samples/mpiblast/test2 rm -f /work/$USER/samples/mpiblast/test2/* cd /work/$USER/samples/mpiblast/test2 cp /opt/sharcnet/mpiblast/1.6.0/examples/il2ra.in il2ra.in gunzip -c /opt/sharcnet/mpiblast/1.6.0/examples/Hs.seq.uniq.gz > Hs.seq.$USER [roberpj@orc-login2:/work/roberpj/samples/mpiblast/test2] ls Hs.seq.roberpj il2ra.in
Create a hidden configuration file using a text editor (such as vi) to define a Shared storage location between nodes and a Local storage directory available on each compute node as followw. Note that the ncbi/data directory is not used in this example and hence can be omitted. If the Local and Shared directories are the same replace --copy-via=mpi with --copy-via=none as will be demonstrated in the below sqsub commands.
[username@orc-login1:/work/$USER/samples/mpiblast/test2] vi .ncbirc [NCBI] Data=/opt/sharcnet/mpiblast/1.6.0/ncbi/data [BLAST] BLASTDB=/work/YourSharcnetUsername/mpiblasttest2 BLASTMAT=/work/YourSharcnetUsername/samples/mpiblast/test2 [mpiBLAST] Shared=/work/YourSharcnetUsername/mpiblasttest2 Local=/tmp
Again partition the database into 8 fragments into /work/$USER/mpiblasttest2 where they will be searched for when a job runs in the queue according to the .ncbirc file, first removing previous partitioning if any such files exist. For this example assume $USER=roberpj however be sure to replace with your username!

Submit a couple of short jobs 15m time limit. If all goes well output results will be written to biobrewA.out and biobrewB.out and the execution time appear in corresponding ofile%J's where %J is the job number as per usual. In these examples we will submit the job from a saw specific directory which can be copied from test2 as follows:
[roberpj@saw-login1:~] module load mpiblast/1.6.0 [roberpj@saw-login1:~] cd /work/roberpj/samples/mpiblast [roberpj@saw-login1:/work/roberpj/samples/mpiblast] cp -a test2 test2.saw [roberpj@saw-login1:/work/roberpj/samples/mpiblast/test2.saw] vi .ncbirc [roberpj@saw-login1:/work/roberpj/samples/mpiblast/test2.saw] cat .ncbirc | grep BLASTMAT BLASTMAT=/work/roberpj/samples/mpiblast/test2.saw
A) Submit job with profile time option choosing n=24 (8 fragments + 8 or greater):
[roberpj@saw-login1:/work/roberpj/samples/mpiblast/test2.saw] rm -f oTime*; sqsub -r 15m -n 24 -q mpi -o ofile%J mpiblast --use-parallel-write --copy-via=mpi -d Hs.seq.roberpj -i il2ra.in -p blastn -o biobrew.out --time-profile=oTime
B) Usage of the debug option again choosing n=16 (8 fragments + 8 or greater):
[roberpj@saw-login1:/work/roberpj/samples/mpiblast/test2.saw] rm -f oLog*; sqsub -r 15m -n 16 -q mpi -o ofile%J mpiblast --use-parallel-write --copy-via=none -d Hs.seq.$USER -i il2ra.in -p blastn -o biobrew.out --debug=oLog
Finally compare /opt/sharcnet/mpiblast/1.6.0/examples/BIOBREW.out computed previously with BLASTN 2.2.15 [Oct-15-2006] with your newly generated biobrew.out output file to verify the results and submit a ticket if there are any problems!
SUPPORTED PROGRAMS IN MPIBLAST
As described in http://www.mpiblast.org/Docs/FAQ mpiblast supports the standard blast programs http://www.ncbi.nlm.nih.gov/BLAST/blast_program.shtml which are reproduced here for reference:
blastp: Compares an amino acid query sequence against a protein sequence database. blastn: Compares a nucleotide query sequence against a nucleotide sequence database. blastx: Compares a nucleotide query sequence translated in all reading frames against a protein sequence database. tblastn: Compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames. tblastx: Compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database.

General Notes
Issue1: Jobs Fail to Start
If the following error message occurs it maybe necessary to stop all mpiblast jobs you are running on the cluster and clear out all the files from /tmp then submit your job again. In the case of Example2 above the following steps work to resolve the problem, where the nodes used from the last run job were red[7-14]. Should there be any questions please open a problem ticket.
Purging Job Node Subset (redfin) pdsh -w red[7-14] ls /tmp/Hs* (confirm existence of file from previous runs) pdsh -w red[7-14] rm -f /tmp/Hs* pdsh -w red[7-14] ls /tmp/Hs* (confirm all files from previous runs removed) Purging Full Cluster (hound) pdsh -w hnd[1-18] -f 4 rm -f /tmp/Hs* pdsh -w hnd[1-18] -f 4 ls /tmp/Hs*

Issue2: Jobs Run for a While then Die
The solution here is to filter the input sequence file. For reasons yet understood the presence of repeat sections results in many thousands of WARNING and ERROR messages rapidly written to the "sqsub -o ofile" output file presumably as mpiblast ignores sequences before eventually diing after several hours, or possibly days.
