NERSC visualization tutorials would be nice.

Many years back I felt NERSC was somewhat weak in providing information concerning movie making. My impression is that things improved but I do not know the current situation. In the last couple years i have used Quicktime Pro to create movies but wonder if tools at NRSC provide more or better capability .
Again, I am ignorant of the current situation and whether there are good tutorials on the NERSC website.

Improved visualization and analysis for large scale data. I would like to see parallel AVS support. I use the existing AVS Express on davinci extensively, but it is already becoming too small and too slow for the size of (M3D nonlinear plasma simulations) run on Franklin, even for jobs that are small by Franklin standards. One reason I am not pushing too hard to increase the size of my Franklin jobs beyond a few hundred cpus is that it will be very difficult to visualize the data at the higher resolution. I don't really know Visit, but from what I have seen the experts do with it, it just does not compare in quality to a developed AVS Express interface.

I need to catch up by using more analysis at NERSC.

Software Comments and Suggestions:   4 responses

it would be great to have python, numpy and sm all linked on the nersc computers.

please install gromacs

Matlab installed by NERSC does not provide complete math support compare to the matlab installed in my own personal computer.

The latest version of NCL (5.1.1) *correctly installed* on davinci ...

Hardware Comments and Suggestions:   3 responses

Many core SMP machines are extremely useful for many of the theories we use, which are necessarily very communication-heavy.

... A new davinci with more standard hardware (not Itanium) and much more of it

clusters with lots of memory and fast turn-around for short jobs

Again, NERSC is the flag ship of DOE supercomputing. A great and valuable resource.

I cannot think of anything more than what NERSC offers now.

None right now.

Data Storage Comments and Suggestions:   2 responses

When I analyze my data, I need a place to do it and computer time to do it with. In theory, davinci would be the place. However davinci has very small disk allocations, so I cannot store the data on davinci for long enough to finish a run. I've been using /scratch, but I keep getting messages about needing to reduce my holdings there.
Alternatively, I can work on franklin:/project. But that's not accessible from batch jobs, and it doesn't accomplish your goal of having me process my data on your data processing machine.

larger space

Lots more help porting code to new platforms. Codes like NIMROD have 5-10 different version, so realize that 5-10 versions need to be ported to new platforms. I think lots of consulting time needs to be allocated to porting code when a new system is brought up.

It would be useful to me if the MOTD were available as a news feed (RSS/ATOM).

I appreciate the generous allocation to our project, but I just found out that our allocation is reduced from 1,000,000 to 750,000. I guess this is due to the policy in place that if some percentage is not used, it will be returned, which I can understand. I also understand that NERSC may return some portion to me, if I request.
However, I would suggest that NERSC should consider this carefully. For instance, I normally test and develop my codes during a first few months of the year, and I do teach classes. But in the summer, I have lots of time. Secondly, we are fortunate to have access NERSC computers, so we use the computing time very carefully and save some time for later big runs. In some cases, the referees will ask us to provide more data, but we do not have time to run it. This is the caution that we have to build in when we use NERSC computers. I have more to say about this, but I suggest to consider this. One option would be to let the users choose a time frame when their peak time period would be during the year.
