IDBA-UD

Genetics, Scientific Software

General information

IDBA-UD 1.1.1 is a iterative De Bruijn Graph De Novo Assembler for Short Reads Sequencing data with Highly Uneven Sequencing Depth. It is an extension of IDBA algorithm. IDBA-UD also iterates from small k to a large k. In each iteration, short and low-depth contigs are removed iteratively with cutoff threshold from low to high to reduce the errors in low-depth and high-depth regions. Paired-end reads are aligned to contigs and assembled locally to generate some missing k-mers in low-depth regions. With these technologies, IDBA-UD can iterate k value of de Bruijn graph to a very large value with less gaps and less branches to form long contigs in both low-depth and high-depth regions.

How to use

To send jobs to the queue you can use the command

send_idba-ud

which after a few questions configures the job.

Performance

IDBA-UD has a good performance and scaling up to 8 cores. Above we did not measure a improvement. In the benchmark the --mimk 40 --step 20 options has been used. When we have decreased the step the the scalling is worse. This trend can be also seen in the second table.

1 core as base 2 cores as base

4 188 2.6 64 1.6 79
8 84 5.7 71 3.5 88
12 92 5.2 43 3.2 54

The second benchark has been done with a bigger file with 10 million bases and the  --mink 20 --step 10 --min_support 2 options. We observe a regular behaviour than in the previous benchmark and how the panellization is good up to 4 cores.

Trinity

Genetics, Scientific Software

General information

2.1.1 release. Trinity, represents a novel method for the efficient and robust de novo reconstruction of transcriptomes from RNA-seq data. Trinity combines three independent software modules: Inchworm, Chrysalis, and Butterfly, applied sequentially to process large volumes of RNA-seq reads. Trinity partitions the sequence data into many individual de Bruijn graphs, each representing the transcriptional complexity at at a given gene or locus, and then processes each graph independently to extract full-length splicing isoforms and to tease apart transcripts derived from paralogous genes. Briefly, the process works like so:

  • Inchworm assembles the RNA-seq data into the unique sequences of transcripts, often generating full-length transcripts for a dominant isoform, but then reports just the unique portions of alternatively spliced transcripts.
  • Chrysalis clusters the Inchworm contigs into clusters and constructs complete de Bruijn graphs for each cluster. Each cluster represents the full transcriptonal complexity for a given gene (or sets of genes that share sequences in common). Chrysalis then partitions the full read set among these disjoint graphs.
  • Butterfly then processes the individual graphs in parallel, tracing the paths that reads and pairs of reads take within the graph, ultimately reporting full-length transcripts for alternatively spliced isoforms, and teasing apart transcripts that corresponds to paralogous genes.

How to use

You can use the

send_trinity

command to submit jobs to the queue system. After answering few questions a script will be created and submitted to the queue system. For advanced users it can be used to generate a sample script.

Performance

Trinity can be run in parallel but it is not very efficient above 4 cores with low performance, as can be seen in the the table. Trinity consumes high amounts of RAM.

ABySS

Genetics, Scientific Software

General Information

1.3.2 version of ABySS (Assembly By Short Sequences). ABySS is a de novo, parallel, paired-end sequence assembler that is designed for short reads. ABySS can be executed in parallel.

See also the installed [intlink id=”6043″ type=”post”]velvet[/intlink] and comparing both we have published article.

How to use

The executables can be found in /software/abyss/bin. To run abyss in a script type in it:

/software/abyss/bin/abyss-pe [abyss-pe options]

Performance

See also the installed [intlink id=”6043″ type=”post”]velvet[/intlink] and comparing both we have published article.

Parallelization

Some benchmarks has been performed with ABySS. They have been performed using file from an Illumina HiSeq2000 NGS with 100 bp per sequence. In the table 1 we can see an example about how ABySS scales as a function of the number of cores. As we can see ABySS scales very up to 8 cores. The results is valid unless for more than 10e6 sequences.

Table 1. Execution time of abyss-pe in seconds as a function the number of cores
cores 2 4 8 12 24
Time (s) 47798 27852 16874 14591 18633
Aceleration 1 1.7 2.8 3.3 2.6
Performance(%) 100 86 71 55 21

Execution time

We have analized as well the execution time as a function of the size of the data. In the table 2 we  observe how from 1 million to 10 millions of sequences the execution time increases by 10 as well. From 10 to 100 millions of sequences the time increases a little more, between 10 t0 20. Therefore, the behavior is more or less lineal.

Table 2. Execution time in seconds of abyss-pe executed in 2, 4 y 8 cores as a function of the number of processed sequences.
sequences 10e6 10e7 10e8
Time in 2 cores (s) 247 2620 47798
Time in 4 cores (s) 134 1437 27852
Time in 8 cores (s) 103 923 16874

RAM memory

In these kind of programs more important than the execution time, which is reasonable, is the RAM memory usage, which can limit the calculation type. In the table 3 we observe how the RAM increases as a function of the number of sequences. We also show the logarithms of the measured values which has been used for a lineal regression. The jobs has been performed in 12 cores.

Tabl3 3. RAM memory used by abyss-pe as a function of the number of processed sequences. The logarithms of the measured values are also shown.
sequences 10e6 5*10e6 10e7 5*10e7 10e8
RAM (GB) 4.0 7.6 11 29 44
log(sequences) 6 6.7 7 7.7 8
log(RAM) 0.60 0.88 1.03 1.46 1.65

From the values of the table we obtain a fitting of the RAM in GB as a function of the number of sequences (s) to the equation

log(RAM)=0.53*log(s)-2.65

o equivalently

RAM=(s^0.53)/447

Conclusion

The memory usage is smaller than in other assemblers like [intlink id=”6043″ type=”post”]Velvet[/intlink], see as well the report Velvet performance in the machines of the Computing Service of the UPV/EHU and comparing both we have published article. In addition, the parallelization with MPI of ABySS allows to aggregate the RAM memory of several nodes to perform larger calculations.

MCCCS Towhee 7.0.2

Biochemistry, Scientific Software, Software_en

Towhee is a Monte Carlo molecular simulation code originally designed for the prediction of fluid phase equilibria using atom-based force fields and the Gibbs ensemble with particular attention paid to algorithms addressing molecule conformation sampling. The code has subsequently been extended to several ensembles, many different force fields, and solid (or at least porous) phases.

General Information

Towhee serves as a useful tool for the molecular simulation community and allows science to move forward more quickly by eliminating the need for individual research groups to rewrite routines that already exist and instead allows them to focus on algorithm advancement, force field development, and application to interesting systems.

Towhee may use different type of ensembles and Monte Carlo moves implemented into Towhee and can alos used different  force fields included with the distribution. (See here for more information )

How to Use

send_towhee

  • To send Towhee to the queue system  use the send_gulp utility. When executed,
    shows the command syntax, which is summarized below:
  • send_towhee JOBNAME NODES PROCS_PER_NODE TIME [ MEM ] [``Other queue options'' ]
JOBNAME: Is the  name of the Output.
NODES: Number of nodes.
PROCS: Number of  processors.
TIME: Time requested to the queue system, format hh:mm:ss.
MEM: Optional. Memory in Gb ( It will used 1GB/core if not set).
[``Other Torque Options'' ] Optional. There is the possibility to pass more variables to the queuing system.
See examples below.   More information about this options

Examples

We send a Towhee job1 to 1 node, 4 processors on that node, with a requested time of 4 hours . The results will be in the OUT file.

send_towhee OUT 1 4 04:00:00

We send job2  to 2 compuation nodes, 8 processors on each node, with a requested time of 192 hours, 8 GB of RAM and to start running after work 1234.arinab is finished:

send_towhee OUT 2 8 192:00:00 8 ``-W depend=afterany:1234'

We  send the input job3 to 4 nodes and 4 processors on each node, with arequested time of 200:00:00 hours, 2 GB of RAM and we request to be send an email at the beginning and end of the calculation to the direction specified.

send_towhee OUT 4 4 200:00:00 2 ``-m be -M mi.email@ehu.es''

send_towhee command copies the contents of the directory from which the job is sent to /scratch or / gscratch, if we use 2 or more nodes. And there is where the calculation is done.

Biochemistry, Scientific Software

General information

4.02 version of the MD program for macromolecules, polymers, ionic systems, solutions and other molecular systems. Developed at the Daresbury Laboratory. In Pendulo the 2.2 version remains. There is already the DL_POLY_CLASSIC version which currently is not been developed.

How to submit to the queue

The program is installed in all the architectures, Arina and Pendulo (DL_POLY 2.2). To execute it include in the scripts:

/software/bin/DL_POLY/DL_POLY.Z

The program will exekute in GPGPUs if it starts in these kind of nodes. Besides, they can be selected by using the gpu label within [intlink id=”244″ type=”post”]the queue system[/intlink].

The GUI is also installed. To execute it use:

/software/bin/DL_POLY/gui

Some utilities has been installed in the /software/bin/DL_POLY/ directory.

Benchmark

We show a small benchmarks performed with dl_ploly_4.02. We stady the parallelization as well as the performance of the GPGPUs.

System 1 cores 4 cores 8 cores 16 cores 32 cores 64 cores
Itanium 1.6 GHz 1500 419 248 149 92 61
Opteron 1230 503 264 166 74
Xeon 2.27 GHz 807 227 126 67 37 25

We show in the firs benchamrk that DL_POLY scales very well and that the xeon nodes are the fastest ones, so we recomend them for large jobs.

System 1 cores 2 cores 4 cores 8 cores 16 cores 32 cores
Itanium 1.6 GHz 2137 303 165 93 47
Opteron 1592 482 177 134 55
Xeon 2.27 GHz 848 180 92 48 28
1 GPGPU 125 114 104 102
2 GPGPU 77 72 69
4 GPGPU 53 50
8 GPGPU 37
System 1 cores 2 cores 4 cores 8 cores 16 cores 32 cores 64 cores
Xeon 2.27 GHz 2918 774 411 223 122 71
1 GPGPU 362 333 338 337
2 GPGPU 240 222 220
4 GPGPU 145 142
8 GPGPU 97

We show that the GPGPUs speedup the calculation but each time we double the number of GPGPUs the speed up is multiplied but only 1.5. Because of this for large number of GPGPUs or cores is better to use the paralelization over cores. For example, one node has 8 cores and 2 GPGPUS. The 2 GPGPUs need 220 s while 8 cores need 411 s. Still 4 GPGPUs are faster than 16 cores but 32 cores with 71 s are faster than 8 GPGPUs that need 97 s. Therefore, the GPGPUS can speedup jobs in PCs or single nodes, but for jobs that require higher parallelization the cores parallelization is more effective.

DL_POLY is designed for big systems and the use up to thousand of cores. According to the documentation:

The DL_POLY_4 parallel performance and efficiency are considered very-good-to-excellent as long as (i) all CPU cores are loaded
with no less than 500 particles each and (ii) the major linked cells algorithm has no dimension less than 4.

Matlab

Maths @en, Scientific Software

General information

Version 7.9 (2009b) in the opteron nodes and 7.12 (2010a) in the Xeon nodes. Mathematical program that includes  high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation.

How to use

Intereactively (with graphical interface):

Matlab is only available for Opteron and Xeon so have to be used interactively from Guinness or Maiz. The graphical interface can be executed with:

matlab

In the queue system

Add the following line in the Torque scripts

/software/bin/matlab < input_file > output_file

where input_file is the file with the matlab commands and output_file is the standar output file name.

With old versions we have had problems with .m files with more than 169 lines. If this happens call your .m program from another small .m program.

To submit the calculation to the nodes add the xeon or the opteron label to submit the calculation to these kink of nodes. In addition, we only have licences to use 2 nodes, so we have the “matlab” special queue to manage them. You must use it. Therefore, your script must contain

#PBS -q matlab
#PBS -l nodes=1:ppn=1:xeon

or for the opteron nodes:

#PBS -q matlab
#PBS -l nodes=1:ppn=1:opteron

Benchmarks

GROMACS

Biochemistry, MM/MD @en, Scientific Software

General information

2018 version. GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles.

It is primarily designed for biochemical molecules like proteins, lipids and nucleic acids that have a lot of complicated bonded interactions, but since GROMACS is extremely fast at calculating the nonbonded interactions (that usually dominate simulations) many groups are also using it for research on non-biological systems, e.g. polymers.

How to use

send_gmx

To send gromacs to the queue system  use the send_gmx utility. When executed, shows the command syntax, which is summarized below:

send_gmx ``JOB and Options'' NODES PROCS_PER_NODE TIME MEM [``Other queue options'']
``JOB and Options'': options for the calculation and input of GROMACS name extension. It is very important to keep the quotes.
NODES: Number of nodes.
PROCS: Number of  processors.
TIME: Time requested to the queue system, format hh:mm:ss.
MEM: Memory in Gb.
[``Otras opciones de Torque'' ] There is the possibility to pass more variables to the queuing system.
See examples below.  [intlink id=”244″ type=”post”] More information about this options[/intlink]

Examples

We send the gromacs input job1 to 1 node, 4 processors on that node, with a requested time of 4 hours and 1 GB of RAM:

send_gmx ``-s job1.tpr'' 1 4 04:00:00 1

We send job2  to 2 compuation nodes, 8 processors on each node, with a requested time of 192 hours, 8 GB of RAM and to start running after work 1234.arinab is finished:

send_gmx ``-s job2.tpr'' 2 8 192:00:00 8 ``-W depend=afterany:1234'

We  send the input job3 to 4 nodes and 4 processors on each node, with a requested time of 200:00:00 hours, 2 GB of RAM and we request to be send an email at the  beginning and end of the calculation to the direction specified.

send_gmx ``-s  job.tpr'' 4 4 200:00:00 2 ``-m be -M mi.email@ehu.es''

send_gmx command copies the contents of the directory from which the job is sent to /scratch or /gscratch, if we use 2 or more nodes. And there is where the calculation is done.

Jobs Monitoring

To facilitate monitoring and/or control of the gromacs calculations, you can use remote_vi which shows the md.log file (only if it was sent using send_gmx).
