Hi, it looks like the core bindings aren't working, can you remove the core= arguments in the blocks?
How many CPU cores does your computer have?

Could you tell me what's happened and how can i solve this ? Thank you !

@telegraphic There are 4 CPUs on my computer. I removed the core=argu
in the blocks, and then i ran it again,i got this:
python test_fft.py
digraph cluster_Pipeline_0 {
"Pipeline_0/BinaryFileReadBlock_0" [label=BinaryFileReadBlock_0 fillcolor=white shape=box style=filled]
ring_0 [fillcolor=deepskyblue shape=ellipse style=filled]
"Pipeline_0/BinaryFileReadBlock_0" -> ring_0
"Pipeline_0/CopyBlock_0" [label=CopyBlock_0 fillcolor=lightsteelblue shape=box style=filled]
ring_2 [fillcolor=limegreen shape=ellipse style=filled]
"Pipeline_0/CopyBlock_0" -> ring_2
ring_0 -> "Pipeline_0/CopyBlock_0"
"Pipeline_0/FftBlock_0" [label=FftBlock_0 fillcolor=white shape=box style=filled]
ring_3 [fillcolor=limegreen shape=ellipse style=filled]
"Pipeline_0/FftBlock_0" -> ring_3
ring_2 -> "Pipeline_0/FftBlock_0"
"Pipeline_0/CopyBlock_1" [label=CopyBlock_1 fillcolor=lightsteelblue shape=box style=filled]
ring_5 [fillcolor=orange shape=ellipse style=filled]
"Pipeline_0/CopyBlock_1" -> ring_5
ring_3 -> "Pipeline_0/CopyBlock_1"
"Pipeline_0/BinaryFileWriteBlock_0" [label=BinaryFileWriteBlock_0 fillcolor=white shape=box style=filled]
ring_5 -> "Pipeline_0/BinaryFileWriteBlock_0"
}

@telegraphic Sorry,there are only 2 CPU cores on my computer, and 4 processors.
Ah, it looks like test_fft.py
assumes that you have five and uses a different core for each block.
Are you still using the GTX 790 and is your user.mk
file setup to target them, ie., GPU_ARCHS ?= 30
?
@jaycedowell No, i'm using GTX 950M. And it works after i change the GPU_ARCHS
in user.mk
and core=argu
in test_fft.py
. So does it means that when i'm using bifrost
,the value of argument core
should be less than or equal to 2 on my computer(with only 2 CPU cores)?
You should be able use as many cores as CPUs listed in /proc/cpuinfo
. For your setup I think that if you changed core=4
to core=3
in the BinaryFileWriteBlock()
then test_fft.py
should run.
@jaycedowell yeah, it works.Thank you! Close now.
