Mounting Lustre Inside Running Container Not Working (Have Added All Capabilities)

Asked 2021-Feb-23 at 21:14

We are trying to mount lustre filesystem inside running container, and have successfully done this via containers which are running in priviledged mode.

However for those containers which are running in non-privilidged mode, mounting lustre failed, even if all capabilites linux provides -- tens of capabilities -- were included!

Then

what is difference between "priviledged: True" and "cap_add: all capabilites"?
Why mounting lustre still fails when all capabilities were added to the container?

This is only an educated guess since I do not know enough about the size of sample and the details of the work being performed by your worker function, main_function

Lets assume that the iterable, sample, that you are passing to the Pool.map method has length 70 and as you said your pool size is 5. The map method will break up the 70 tasks into chunksize-sized groups of tasks distributing these chunks to each of the 5 processes in the pool. If you do not specify the chunksize argument to the map method it computes the value based on the size of the iterable (70) and the size of the pool (5) as follows:

I've recently started to work with XML and XSLT and I've encountered a problem that I'm having trouble solving.

I have a project in which I need to create an XSLT that works with 3 different objects in XML.

The objects are expositions.

QUESTION

Need test to determine if asynchronous I/O is actually happening in C code

Asked 2020-Dec-01 at 22:18

I am new to asynchronous I/O. I need to get it working in some C and Fortran programs on a Linux system. I managed to write a little C test code (included below) that reads asynchronously from two files. The code compiled and ran. What I am wondering, though, is whether I am truly getting asynchronous I/O, or is the I/O really serial? The lustre file system I am dealing with is a bit outdated and it is not clear that it actually supports asynchronous I/O, and no one seems to have a definite answer. So I am wondering are there some timing statements or any kind of output I can add to the code to determine whether it is functioning in a truly asynchronous manner. I'm betting I'll need much larger files than what I am dealing with to do a meaningful test. No idea what else I need.

The code is:

From man aio, note that aio_* is wholly a glibc [userspace] implementation.

So, as mentioned, it has some limitations.

The way to see what's going on, timewise, is to have an event log with timestamps.

The naive approach is to just use [debug] printf calls. But, for precision time measurements, the overhead of printf can disrupt the real/actual timing. That is, we don't measure "the system under test", but, rather, "the system under test + the timing/benchmark overhead".

One way is to run your program under strace with appropriate timestamp options. The strace log will have information about the syscalls used. But, because aio is implemented in userspace, it may not be able to drill down to a fine enough grain. And, strace itself can impose an overhead.

Another way is to create a trace/event log mechanism and instrument your code. Basically, it implements a fixed length ring queue of "trace elements". So, the trace data is stored in memory, so it's very fast.

A standard utility that can help with this is dtrace. I've not done this myself, as I've preferred to "roll my own". See below for some actual code I've used.

Then, instrument your code with (e.g.):

ANSWER

Answered 2020-Oct-30 at 16:16

Since your current (home) directory has a file named a.exe , the shell is expanding *.exe, and you are effectively running the command

$ locate a.exe

Try it either without the asterisk or with an escaped asterisk

$ locate \*.exe

Dataproc: Hot data on HDFS, cold data on Cloud Storage?

Asked 2020-Mar-10 at 22:02

I am studying for the Professional Data Engineer and I wonder what is the "Google recommended best practice" for hot data on Dataproc (given that costs are no concern)?

If cost is a concern then I found a recommendation to have all data in Cloud Storage because it is cheaper.

Can a mechanism be set up, such that all data is on Cloud Storage and recent data is cached on HDFS automatically? Something like AWS does with FSx/Lustre and S3.

...

ANSWER

Answered 2020-Mar-09 at 22:20

What to store in HDFS and what to store in GCS is a case-dependant question. Dataproc supports running hadoop or spark jobs on GCS with GCS connector, which makes Cloud Storage HDFS compatible without performance losses.

Cloud Storage connector is installed by default on all Dataproc cluster nodes and it's available on both Spark and PySpark environments.
