            Is there a way to permute inside using to variables in bash?
            Asked 2021-Dec-09 at 23:50

            I'm using the software plink2 (https://www.cog-genomics.org/plink/2.0/) and I'm trying to iterate over 3 variables.

            This software admits an input file with .ped extention file and an exclude file with .txt extention which contains a list of names to be excluded from the input file.

            The idea is to iterate over the input files and then over exclude files to generate single outputfiles.

            1. Input files: Highland.ped - Midland.ped - Lowland.ped
            2. Exclude-map files: HighlandMidland.txt - HighlandLowland.txt - MidlandLowland.txt
            3. Output files: HighlandMidland - HighlandLowland - MidlandHighland - MidlandLowland - LowlandHighland - LowlandMidland

            As I understand it you are trying to identify all possible matches for the jumbled string in your list. You could sort the letters in the jumbled word and match the resulting list against sorted lists of the words in your data file.

            You can match your non-X containing FASTA entries with the regex >.+\n[^X]+\n. This checks for a substring starting with > having a first line of anything (the FASTA header), which is followed by characters not containing an X until you reach a line break.

            Does Apache Spark 3 support GPU usage for Spark RDDs?
            Asked 2021-Sep-23 at 05:53

            I am currently trying to run genomic analyses pipelines using Hail(library for genomics analyses written in python and Scala). Recently, Apache Spark 3 was released and it supported GPU usage.

            I tried spark-rapids library start an on-premise slurm cluster with gpu nodes. I was able to initialise the cluster. However, when I tried running hail tasks, the executors keep getting killed.

            On querying in Hail forum, I got the response that

            That’s a GPU code generator for Spark-SQL, and Hail doesn’t use any Spark-SQL interfaces, only the RDD interfaces.

            So, does Spark3 not support GPU usage for RDD interfaces?

            ...

            ANSWER

            Answered 2021-Sep-23 at 05:53

            As of now, spark-rapids doesn't support GPU usage for RDD interfaces.

            Source: Link

            Apache Spark 3.0+ lets users provide a plugin that can replace the backend for SQL and DataFrame operations. This requires no API changes from the user. The plugin will replace SQL operations it supports with GPU accelerated versions. If an operation is not supported it will fall back to using the Spark CPU version. Note that the plugin cannot accelerate operations that manipulate RDDs directly.

            Here, an answer from spark-rapids team

            Source: Link

            We do not support running the RDD API on GPUs at this time. We only support the SQL/Dataframe API, and even then only a subset of the operators. This is because we are translating individual Catalyst operators into GPU enabled equivalent operators. I would love to be able to support the RDD API, but that would require us to be able to take arbitrary java, scala, and python code and run it on the GPU. We are investigating ways to try to accomplish some of this, but right now it is very difficult to do. That is especially true for libraries like Hail, which use python as an API, but the data analysis is done in C/C++.

            Usage of compression IO functions in apache arrow
            Asked 2021-Jun-02 at 18:58

            I have been implementing a suite of RecordBatchReaders for a genomics toolset. The standard unit of work is a RecordBatch. I ended up implementing a lot of my own compression and IO tools instead of using the existing utilities in the arrow cpp platform because I was confused about them. Are there any clear examples of using the existing compression and file IO utilities to simply get a file stream that inflates standard zlib data? Also, an object diagram for the cpp platform would be helpful in ramping up.
