I'm running iperf2 on ubuntu18.04 and trying to test the max bandwidth with one CPU. My topology is client(with CX5 100G nic)->switch(100G)->server(with CX5 100G nic).
Unfortunately, the speed is only 30Gbps. Then I do a loopback test, the speed is 60Gbps and the cpu usage is 100%. What should I do?

For one thing, your loopback test will likely have a much larger packet size than your over-the-network test. That will mean TCP needs to to fewer trips up/down the protocol stack to transfer a given quantity of data.
For another, your loopback test will not include any of the overhead for the driver of your 100G NIC.
Also, one of the many limits to the performance of a TCP connection is:
Throughput <= WindowSize / RoundTripTime
and while the round-trip time on your small 100G setup may be small, they are still longer than loopback, and you are trying for a throughput which is quite large, so the default limits for the TCP window size of your stack may be impeding getting higher throughput.

At about 12 minutes the optimisation stops, it says 1 solution but displays no solution. In the profiler tab I get the Overflow occurred, please use oplrun -profile message.

Kindly suggest how to overcome this problem.
Use better units. An objective value of 8.95478e+11 indicates you are using cents instead of billions of dollars. Also, make sure any big-M constants are not larger than needed.
I encountered an OOM error while running tensorflow code. I am confused about these indicators, such as Limit, InUse, MaxInUse, NumAllocs, MaxAllocSize. Can anyone help explain it?thanks!

So it seems that Tensorflow is using GPU.
When I profile the code,

I expect a significant speed up when using GPU for training. How can I fix this? Can someone help me to understand what is causing the slowdown? Thank you.
Couple of observations:
Use CuDNNLSTM instead of LSTM to train on GPU, you will see considerable increase in speed.
Sometimes, for very small networks, the overhead of transferring between CPU and GPU outweighs the parallel computations made on GPU; in other words, there is more time lost on transferring the data than time gained by training on GPU.
GPUs should be used for highly intensive tasks and computations (very big LSTM/heavy CNN networks). Nevertheless, for very small MLPs and even small LSTMs you might observe that the network trains equally fast on CPU and GPU or that in some particular cases the speed on CPU is even better (very particular cases with super small networks).
UPDATE FOR TENSORFLOW >= 2.0
The imports default to using CuDNNLSTM/CuDNNGRU if the video card is detected; therefore it is not needed explicitly to import them.
I would like to perform two different calculations across consecutive columns in a pandas or pyspark dataframe.
Columns are weeks and the metrics are displayed as rows.
I want to calculate the actual and percentage differences across the columns.
The input/output tables incl. the calculations used in Excel are displayed in the following image.
I want to replicate these calculations on a pandas or pyspark dataframe.

in pandas you could use pct_change(axis=1) and diff(axis=1) methods:
df = df.set_index('Metrics')
# list of metrics with "actual diff"
actual = ['AOV', 'Attachment Rate']
rep = (df[~df.index.isin(actual)].pct_change(axis=1).round(2)*100).fillna(0).astype(str).add('%')
rep = pd.concat([rep,
df[df.index.isin(actual)].diff(axis=1).fillna(0)
])

I am running a MapReduce job but the reduce task always restarts at 0% without any failure. I can't find anything related to this on the web. Any help?
