[Hdf-forum] C# and HDF5

My client uses HDF5 extensively via MetLab but would like to write an application in C#/.net. I am new HDF5 but a very versed C# programmer. I am not finding much documentation on the dotnet wrapper. Can anyone point me to some resources that may help?

[Hdf-forum] Reshaping an Array in HDFView

Is there a way to reshape an array with HDFView? I have an array that is stored as a 1D array but in reality it can be interpreted as a 2D Image. So I would like to be able to open the data array as an image in HDFView but somehow tell the dialog box to convert the array from a 1D to a 2D

Re: [Hdf-forum] Reshaping an Array in HDFView

Not possible with the default implementation. You could extend DefaultImageView.java to map a 1D array to an 2D image. Thanks --pc On 4/8/2013 1:23 PM, Michael Jackson wrote: Is there a way to reshape an array with HDFView? I have an array that is stored as a 1D array but in reality it can

wow, you find out this. We registered the domain name for our C# and Powershell project. Gerd (our application architect) and his wife made the PSH5X movie . Thanks --pc On 4/8/2013 4:06 PM, Rob Latham wrote: On Fri, Apr 05, 2013 at 12:16:03PM -0500, Charles Henderson wrote: My client uses

[Hdf-forum] Performance query

Hi, I have a question regarding the performance of parallel I/O vs MPI communication based calls. I have data which needs to be accessed by different processors. If the data is in memory then MPI calls (Send/Recv) does the job. In an another scenario the data is written to a H5 file and

Re: [Hdf-forum] Performance query

Hi Mark, Thank you for answering my question. You are right about the practicality issue. This isn't a serious issue if the data is stored in a distributed sense with some indicators specifying which processor has the data. This data is treated as a background database and it doesn't move

Re: [Hdf-forum] Performance query

Hi Suman, I think you are hinting at the fact that unstructured data is harder to manage with true concurrent parallel I/O to a single, shared file, right? Yeah, it is. Honestly, I don't have much experience with that. My impression has always been that the more information you can give HDF5

Re: [Hdf-forum] Performance query

Thanks a lot Mark. Collective communication may not always be possible as two processors may access to the same data. Are you suggesting that one needs to separate I/O requests into collective and independent modes? Can one do a collective I/O even when the data is non-contiguous? Regards Suman
