Hi Barry, Just curious: Do you have any particular recommendations for how you would change the API? I am not a fan simply because the API is very "BLAS like". I'm wondering if that is your primary objection, or if there is anything that specifically sticks out as an annoyance. (I have yet to d

Hi Richard/Barry, I don't have any particular need just yet, but since most HPC clusters have Intel CPUs, I think an Intel Sparse MKL PETSc branch would bring immediate optimisations. I do realise that it does require quite a bit of work as Intel probably didn't design the API that well and which

Hi Wadud, I work at Intel and plan to add support for the inspector-executor sparse BLAS routines (https://software.intel.com/en-us/node/590105) soon. (I think this should be straightforward but it's been a question of simply finding the time.) I will add a subclass of MATAIJ that uses these. D

We're always happy to accept contributions. Intel unfortunately made some terrible choices for APIs for these things so it is unlikely without a specific funding source that we would ourselves add code to PETSc to utilize them. Barry > On Dec 18, 2015, at 12:49 PM, W. Miah wrote: > > H

Hi, Do you have any plans for a PETSc port that uses the optimised Intel MKL sparse BLAS: https://software.intel.com/en-us/node/520797 I think this will be an interesting optimisation exercise. Best regards, -- web: http://miahw.wordpress.com mobile: +447905 755604 gpg: 4CC2 1A75 BDFB 2E29 B2

Hi all, What's the status on the implementation of the parallel mesh reader/generator for DMPlex meshes? Is anyone actively working on this? If so is there a branch that I can peek into? Thanks, Justin

Hi Venkatesh, it sounds like a job for the batch scheduler; again, a "bash" problem, with some additional variables: On a RHEL cluster, I was using Torque/PBS, which gives the `qsub`, `qstat` commands. I would guess that Cray has analogous ones . PETSc and SLEPc are instead toolkits for splitti

Hi, I have access to Cray with many cores. It takes about 100 secs to solve in a single core. If I require to solve it sequentially, it will take a lot of time. Ok I can ask the admins, but in case you have an idea, pls. let me know. Best Regards, Venkatesh On Fri, Dec 18, 2015 at 2:32 PM, Timoth

You need to be more specific, what kind of machine do you have ? If you have very few cores, it will not help much to launch them all at the same time, but at least you can make the thing automatic using the loop as I told you. Your computer will solve the first problem and then automatically go to
