resources - Maximum instructions per CUDA kernel? Maximum operations per CUDA stream? -


is there maximum number of cuda operations may pending specific cuda stream? haven't seen such limit in documentation.

i interested in related figure of maximum number of instructions per cuda kernel.

there maximum number of cuda ptx instructions per kernel:

  • 2 million gpus compute capability under 2.0 (i.e. before fermi microarchitecture)
  • 512 million gpus compute capability 2.0 or higher (e.g. fermi, kepler, maxwell, ...)

this information can found in cuda c programming guide, "maximum number of instructions per kernel".

as streams, if kernels run on given stream respect limit, there no such stream instruction limit. @talonmies pointed out, streams host side queue of operations, have nothing loading code onto gpu.

matlab - How to equate a structure array to structure array -

the following code doesn't work, think it's clear want do: my.struct = 1; foo.bar = my.struct; so that foo.bar.struct = 1 basically want fill in my structure array bunch of fields , values. want place struct nested struct within foo.bar while retaining field names. my.struct = 1; foo.bar = my.struct; this places value of my.struct (= 1 ) in foo.bar . of course foo.bar 1 . i think you're after this: my.struct = 1 foo.bar = my;
