kandi X-RAY | arena Summary

arena is a Go library typically used in Artificial Intelligence, Machine Learning, Tensorflow, Docker applications. arena has no bugs, it has a Permissive License and it has low support. However arena has 2 vulnerabilities. You can download it from GitHub.

Arena is a command-line interface for the data scientists to run and monitor the machine learning training jobs and check their results in an easy way. Currently it supports solo/distributed TensorFlow training. In the backend, it is based on Kubernetes, helm and Kubeflow. But the data scientists can have very little knowledge about kubernetes. Meanwhile, the end users require GPU resource and node management. Arena also provides top command to check available GPU resources in the Kubernetes cluster. In one word, Arena's goal is to make the data scientists feel like to work on a single machine but with the Power of GPU clusters indeed. For the Chinese version, please refer to 中文文档.

            How can I fix this? " HEAP CORRUPTION DETECTED after normal block.. CRT detected that the application wrote to memory after end of heap buffer "
            Asked 2022-Apr-01 at 00:09

            I had a program working good (without prompting errors) using references, but I decided to use a pointer-to-pointer array allocated on virtual memory, because I can use a variable as the size of the array.

            The error prompts when I break the while (m_Window.isOpen()) loop, in other words when I close the game window and the game is finished. I have noticed that the program breaks when I try to erase the virtual memory in the Engine::cleanVirtualMemory() function. I have noticed that it is there because I have put two flags (cout << "running1" << endl; and cout << "running2" << endl) and I can show just the first flag.

            Then it prompts a window with the following message:

            ANSWER

            Answered 2022-Mar-05 at 23:44

            What does java/SO do in order to reserve this memory without being counted by RSS (linux memory measure) statistics?

            This kind of "reservation" is based on the concept of Virtual Memory. The JVM calls mmap to reserve an address space. Initially these addresses are just numbers not backed by physical pages. On the first access to a virtual page, a page fault happens, and the OS handles it by allocating the backing storage (physical RAM or a swap space).

            Could other process use this memory due that is no physically reserved?

            In short, yes. A longer answer - depends on the OS settings, specifically, vm.overcommit_memory and vm.overcommit_ratio sysctls. The default settings allow overcommitment - i.e. it's possible to allocate more virtual memory than available physical RAM + swap (because applications often do not use all virtual memory they reserve).

            QUESTION

            Why does isolating tasks in task arenas to NUMA nodes for memory locality slow down my embarassingly parallel TBB application?
            Asked 2022-Feb-15 at 11:46

            I have this self-contained example of a TBB application that I run on a 2-NUMA-node CPU that performs a simple vector addition repeatedly on dynamic arrays. It recreates an issue that I am having with a bit more complicated example. I am trying to divide the computations cleanly between the available NUMA nodes by initializing the data in parallel with 2 task_arenas that are linked to separate NUMA nodes through TBB's NUMA API. The subsequent parallel execution should then be conducted so that that memory accesses are performed on data that is local to the cpu that computes its task. A control example uses a simple parallel_for with a static_partitioner to perform the computation while my intended example invokes per task_arena a task which invokes a parallel_for to compute the vector addition of the designated region, i.e. the half of the dynamic arena that was initialized before in the corresponding NUMA node. This example always takes twice as much time to perform the vector addition compared to the control example. It cannot be the overhead of creating the tasks for the task_arenas that will invoke the parallel_for algorithms, because the performance degradation only occurs when the tbb::task_arena::constraints are applied. Could anyone explain to me what happens and why this performance penalty is so harsh. A direction to resources would also be helpful as I am doing this for a university project.

            ANSWER

            Answered 2022-Feb-15 at 11:46

            Part of the provided example where the work with arenas happens is not one-to-one match to the example from the docs, "Setting the preferred NUMA node" section.

            Looking further into the specification of the task_arena::execute() method, we can find out that the task_arena::execute() is a blocking API, i.e. it does not return until the passed lambda completes.

            On the other hand, the specification of the task_group::run() method reveals that its method is asynchronous, i.e. returns immediately, not waiting for the passed functor to complete.

            That is where the problem lies, I guess. The code executes two parallel loops within arenas one by one, in a serial manner so to say. Consider following the example from the docs carefully.

            BTW, the oneTBB project, which is the revamped version of the TBB, can be found here.

            EDIT answer for the EDITED question:

            1. See the comment to the question.
            2. The waiting should happen after work is submitted, not before it. Also, no need to go to another arena's task group to do the wait within the loop, just submit the work in the NUMA loop via arena[i].execute( [i, &] { task_group[i].run( [i, &] { /*...*/ } ); } ), then, in another loop, wait for each task_group within corresponding task_arena.

            Please note how I capture the NUMA loop iteration by copy. Otherwise, the code might be referring the wrong data inside the lambda body.

            Correct BigInt Fibonacci Implementation in Zig Lang

            I am new to Zig Lang, and I was searching for an existing implementation for Big Int Fibonacci to no avail.
