CUDA is cool if you know how to use it.

Re: HW10 Timings and Results

I am not sure what's wrong, but I am not getting any speedup on euler. Below are results from both euler and my system.

Re: HW10 Timings and Results

Using doubles, I get

Serial Result = 32.121089
Serial Time = 153.495 ms

Max threads = 64
OpenMP Result = 32.121089
OpenMP Time = 5.968 ms

This apparently ran on an AMD, since I told qsub to request 64 processors per node. But I'm not sure how I would have run it on an Intel, or how to tell that it ran on an Intel.

Goldy,

It looks like you were running that test on Euler's head node. Do you still get no speedup if you use qsub?

Re: HW10 Timings and Results

Hi Paul,
The one above, I tried on euler01. I also tried qsub, but was not getting speedup.
  Code:
qsub -I -l nodes=1;ppn=16

Re: HW10 Timings and Results

Serial execution(Intel):
Final result is 32.121041
Execution time: 128.911397ms

Using openMP on Intel with 16 cores
[skumaraswamy@euler01 HW10]$ ./openMP 16
Max number of threads 16
Number of threads requested 16
Final result is 32.121041
Execution time: 11.580883ms


Using openMP (AMDwith 64 cores)
[skumaraswamy@euler26 HW10]$ ./openMP 64
Max number of threads 64
Number of threads requested 64
Final result is 32.121041
Execution time: 6.238867ms
