I'm pretty sure a gpuArray has a type (e.g., single or double). But i'm not sure how to check it. The function isa does not work for gpuArray. A = gpuArray(single(1)); B = gpuArray(double(1)); isa(B,'double')
例如: 有时候GPU受限于硬件架构,单精度的计算远快于双精度。这时候可以考虑在拷贝的时候顺便转换一下精度:A=gpuArray(single(B c#调用matlab函数之——未经处理的异常: System.TypeInitializationException: 解决方案 仅作为操作记录,大佬请跳过。 背景: 博主visual studio2019,matlab2019a,64位win10 c#调用matlab函数...
matlab里如何把gpuarray single改为普通的array 1 并行问题的由来——从抛硬币说起 举个简单的例子:抛100次硬币统计正面向上的次数。我们可以拿一个硬币重复地抛100次。但有人嫌麻烦,就想能不能再叫一个人带另外一个硬币过来,两个人同时抛,这样每个人就能只抛50次了,节约了时间,并行的思想初现。问题来了,...

I just started to use a A100 80GB PCIe anticipating to calculate eig() on a single very large matrix close to half of the GPU memory size. And I found this post. The gpuArray size limit of intmax('uint32') seems to be too restrictive these days. It means I cou...

MATLAB uses dominant argument dispatching to determine which version of a method to call. During method dispatching, MATLAB determines the dominant class from among the arguments in the call. In general, all MATLAB classes defined using the classdef syntax have equal precedence for purposes of ...
