QUESTION
I'm trying to extract the spectral axis of a FITS data set using astropy/spectral_cube. Specifically I want to convert the channel values into velocity values, accounting for the different radio/optical conventions and rest frequency of the spectral line being examined. This is working just fine for one FITS file but not for another. I presume this is due to a difference in the headers, but I can't figure out what the critical difference is.
My code :
...ANSWER
Answered 2021-Feb-12 at 08:47Okay, after a week of being utterly perplexed, I found a solution !
The problem was indeed the gridding. Every non-AGES cube I tried had no spectral coordinate problems with astropy or spectral-cube at all. I didn't think it would be so unusual to grid the data to have constant frequency channel width but varying velocity width, but apparently it is. What really baffled me was that if no transformation is applied to the axis then the values are correct, but if any keywords are provided to the with_spectral_unit command - even if only to keep the cube in its native units - then the values are all wrong.
After trying every adjustment to the header I could think of, I found the miriad task velsw which can convert between different velocity axes. Directly setting the velocity convention that I wanted (optical) did not work, giving a similar - though not identical - error to the spectral-cube conversion. However, the task instructions give a warning that "non-linear axes are only correct to first-order at the reference point". So the answer is to convert to frequency, which in this data is linear. Then spectral-cube can handle the conversion back to velocity with near-as-dammit perfect accuracy.
Using velsw is a fast and easy workaround as it only transforms the header values (it doesn't regrid the data). The downside is that one first has to convert to miriad's own format and back to fits (using the fits task for anyone unfamiliar with miriad). I imagine it should be possible to convert the header values directly using spectral-cube to skip this step, but I'll post a separate question if I can't figure out how to do that.
QUESTION
I have a big multithreaded system in C#, and I realized that performance was very different between two threads. Now I have designed two nearly identical threads, where one performs 4-5 times faster (And it scales up linearly if you change the amount of loops they have to run). And the difference? One clumsy condition surrounding the actual heavy code of one of them. It makes no sense to me, and I feel powerless in optimizing going forward, if such a minor detail can have such a huge impact. This was tested in Unity, and as such it could be that the result is different in other environments.
ThreadA finish time: 2.8 seconds. ThreadB finish time: 0.6 seconds.
Mind you ThreadB is the one that has a condition (Which will evaluate to true instantly on first while iteration). How can such a stupid addition to the code make the actual payload (The for loops and the number crunching) perform so much faster? Also, if I change the "delay" variable with a static "0.0" directly in the condition of ThreadB, it performs like ThreadA again. In other words: One single double, and whether it is a hardcoded value, or references a variable, makes a difference in performance of a factor of 4-5.
Never mind the actual algorithm, which is only there to make the computer crunch some numbers. I know I am comparing the same data again and again, that is besides the point.
I am no compilation nerd, and I have no way of probing how this differs in actual machine/assembler code. I just know that the difference is huge, and non sensical to me. What do I miss? I discovered this by accident, and in the future I may not have any way of knowing a given thread performs at 20% possible speed, and that one slight change could solve it.
Please. I need a nerd to make this going from pure magic to "Oh, that's why...! Now I know how to avoid it in the future...". I know compilation of C# is surrounded by layers of managed stuff, but there must be a logical reason. Right?
Here is some test code with some simple structs to support it. If anyone has the time to check if they get the same results as I, I would be happy.
...ANSWER
Answered 2020-Nov-27 at 10:47Solved... Was a Unity specific compilation problem. Changed Scripting backend from Mono to IL2CPP which not only made everything perform WAY better, but also removed this problem as described. So JIT compilations was to blame. Still not sure how such a stupid inclusion of a clumsy condition made my the thread perform way better than without it, but now it works. And I learned a ton by fixing it.

QUESTION
after few deployment of openstack (packstack all-in-one) I founded that (from hypervisor summary) the local storage size is around 40G-50G. The disk storage that I deployed is actually around 150G and 250G but keep getting around 40-50G in openstack. The same behavior when I run over VM and baremetal. During OS(Centos7) installation I just using default auto setup...all storage size (sda) and never set manual. For example this is the VGS output from VM with 150G storage running openstack
...ANSWER
Answered 2020-Oct-16 at 05:19What do you mean by storage size? If you mean the amount of storage for Cinder volumes, adjust the CONFIG_CINDER_VOLUMES_SIZE parameter. The documentation isn't clear about it, but I think the number is in Gigabytes. However, this only works if your root filesystem has enough space.
If you mean ephemeral storage, you also need to have a root filesystem that is large enough. I see that your system has three LVM volumes for root, swap and home. My suspicion is that your root volume (named centos-root) is too small. If that is the case, create a Centos installation that does not separate root and home and try again.
Adding additional information to answer the below questions:
The storage size reported in the hypervisor summary refers to the space available in Nova's instances directory, probably under /var/lib/nova (not sure). Which is on your root filesystem.
Packstack uses an LVM volume group as the storage backend for Cinder. The physical volume for that volume group resides on a loop device /dev/loop1, which is a file that resides on the root filesystem. Therefore, Cinder's storage does take up space in your root filesystem. Use the command losetup -a
to see that file.
