Re: [Discuss-gnuradio] File sink causes "S" errors

Hi Josh,

How is the sustained rate when you simultaneously run rx_streaming_samples (without dump) and dd?

:-)

Acutally, the result I got is more than unexpected. :o)

Running dd in one terminal and rx_streaming_samples in a second terminal gives me this:

Terminal 1:

> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 19.7982 s, 51.7 MB/s
> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 14.2399 s, 71.9 MB/s
> dd if=/dev/zero of=/SSD/test2.bin bs=10000K count=100
100+0 records in
100+0 records out
1024000000 bytes (1.0 GB) copied, 10.7249 s, 95.5 MB/s


Terminal 2:

./rx_streaming_samples -f 1.575G -d 4 -N 1000000000 -s -o /SSD/test.bin
S

A single "S" occurrence (!!!) although I used decimation of 4!!! How can you explain this?

Regards,
