            As your value is optional so it prompt error warning you value may be undefined and it may not be able to retrieve the next property [key]

            However, you already handled it in the code when value is undefined, you assigned a empty object {} to it:

            functions props change doesn't occurs child component render why?
            Asked 2021-Jun-04 at 08:01

            I have App, TseTest(which has msg props) components and TseTest have variables a, b and each values have random number and it prints values on console.

            When I press button then msg state in App will change function () {console.log("t");} to function () {console.log("tt");}

            And I expected TesTest will rerender due to msg is changed and prins a,b on console with new values but it's not.

            It seems props of function type is not occurs render when it changes.

            useState takes a function which is actually used for lazy initialization of state i.e. for the first time whatever is returned from this function will be set to initial state.

            I faced a problem writing a twocolumn article in latex. I incorporated a regular table in singlecolumn mode, but when i change it back to doublecolumn below the table, when the text or the proof is large enough to start the second column, it goes over the table , which means that the second column starts at the beginning of the page as if the table doesnt exist. I left as comments the commands that i tried but didnt work. thank you for your time.

            Instead of explicitly switching the text from one column to two columns back and forth within a page, you can use the starred (*) version of the table environment. That will make this table one-column, while the text stays as it is.

            QUESTION

            Is there a benefit (in terms of computation time) of using torch.float32 instead of torch.float64 on Nvidia Tesla K20c?
            Asked 2021-Feb-17 at 03:08

            Somewhere I read that "unless you have a Tesla card, float64 is 32 times slower than float32 on GeForce, Quadro and Titan cards on any recent cards ( Maxwell and Pascal so since 2014)."

            So I am wondering would the computation be faster for float32 than float64 on tesla gpu or the performance remains same. I am specially interested in time taken in multiplication of two vectors.

            Ofcourse, float32 would take less memory than float 64. But for my application memory is no issue.

            So I am wondering would the computation be faster for float32 than float64 on Tesla GPU or the performance remains same.

            32 bit floating point has higher theoretical maximum throughput on all NVIDIA GPUs. The K20c is a compute capability 3.5 GPU, you can see here that the maximum FMAD instruction throughput per SM per clock is three times higher for float32 compared to float64. Other instructions may have even wider performance differences.

            I am specially [sic] interested in time taken in multiplication of two vectors.

            That would be implementation specific and probably depends on how Pytorch works internally. That isn't directly related to CUDA.

            Ofcourse, float32 would take less memory than float 64. But for my application memory is no issue.

            But memory bandwidth might be, and peak memory throughput for float64 is half that of float32. A 64 bit type also potentially introduces a two-way shared memory band conflict where 32 bit types have none.
