QUESTION

Wrong result calculation Hour angle from altitude azimuth

Asked 2022-Feb-04 at 16:31

I am making a Javascript program and on of the functions is to convert altitude/azimuth to right-ascension/declination given a time and latitude. My code can find the declination fairly accurately, I checked with Stellarium. I have been using this site to help me with the math.

My program gives me the wrong value for horizontal ascension which I plan on using to find right ascension (I already have a function to find local sidereal time which works). Here is my code for the equation
var ha = asin(-sin(az)*cos(alt) / cos(dec)) * (180 / Math.PI); this code is in Javascript but I defined custom sin/cos/asin functions that take degrees as input and return radians because that is the form my data is in.

The site I use also says that this equation should give the same result
var ha = acos((sin(alt) - sin(lat)*sin(dec)) / (cos(lat) * cos(dec))) * (180 / Math.PI);
but, the two equations give different results and neither are correct according to stellarium. I have checked that all the variables I am putting in are correct and I am almost certain I entered the equation correct. Here is the full code on github. I need help figuring out how to fix this problem.
--Note this can be run with node js with no libraries The result I get is { ra: [ 23, 57, 37.9 ], dec: [ -5, 24, 38.88 ] }
It should be getting { ra: [ 5, 36, 22.6 ], dec: [ -5, 24, 38.88 ] it does not have to be exact, I only really care about the first number of ra (right ascension). It is also formatted in HMS format. The datetime is hardcoded to Febuary 1st 2022 12:00:00 so that is what you should set stellarium to if you are testing this out.

Here is the relevant code

Give the following a try. Notable changes include:

Specified 'GMT+0000' when establishing J2000.0 date, in addition to the date being passed in to altazToradec(). Otherwise, new Date() returns local time.
Sourced calculation of 'DEC' and 'HA' from MathWorks.com (look under the "Functions" tab).
NOTE: 'HA' and 'RA' are in degrees, not hours. To convert to hours, multiply by (24 hrs / 360 deg), or simply divide by (15 deg / hr).
Sourced sample data from StarGazing.net.

INFO JVM Arguments . . . -XX:+HeapDumpOnOutOfMemoryError - is the node out of Memory?

Asked 2020-Jul-22 at 07:57

Does the below INFO message that appears on server logs indicate that the node has run out of memory ?

INFO 15:08:37 JVM Arguments: [-Dorg.xerial.snappy.tempdir=/app/apigee/data/apigee-cassandra/data/tmp, -Dorg.xerial.snappy.tempdir=/app/apigee/data/apigee-cassandra/data/tmp, -ea, -javaagent:/app/apigee/apigee-cassandra-2.1.16-0.0.1123/bin/../lib/jamm-0.3.0.jar, -XX:+CMSClassUnloadingEnabled, -XX:+UseThreadPriorities, -XX:ThreadPriorityPolicy=42, -Xms8192M, -Xmx8192M, -Xmn1200M, -XX:+HeapDumpOnOutOfMemoryError, -Xss256k, -XX:StringTableSize=1000003, -XX:+UseParNewGC, -XX:+UseConcMarkSweepGC, -XX:+CMSParallelRemarkEnabled, -XX:SurvivorRatio=8, -XX:MaxTenuringThreshold=1, -XX:CMSInitiatingOccupancyFraction=75, -XX:+UseCMSInitiatingOccupancyOnly, -XX:+UseTLAB, -XX:CompileCommandFile=/app/apigee/apigee-cassandra-2.1.16-0.0.1123/bin/../conf/hotspot_compiler, -XX:CMSWaitDuration=10000, -XX:+CMSParallelInitialMarkEnabled, -XX:+CMSEdenChunksRecordAlways, -XX:CMSWaitDuration=10000, -Djava.net.preferIPv4Stack=true, -Dcom.sun.management.jmxremote.port=7199, -Dcom.sun.management.jmxremote.rmi.port=7199, -Dcom.sun.management.jmxremote.ssl=false, -Dcom.sun.management.jmxremote.authenticate=false, -Dcom.sun.management.jmxremote.password.file=/app/apigee/data/apigee-cassandra/jmxremote.password, -javaagent:/app/apigee/apigee-cassandra-2.1.16-0.0.1123/bin/../lib/jolokia-jvm-1.3.5-agent.jar=host=0.0.0.0, -Dlogback.configurationFile=logback.xml, -Dcassandra.logdir=/app/apigee/apigee-cassandra-2.1.16-0.0.1123/bin/../logs, -Dcassandra.storagedir=/app/apigee/apigee-cassandra-2.1.16-0.0.1123/bin/../data, -Dcassandra-foreground=yes]

This entry is being used by the Ops team to suggest that the node has run out of memory.

My belief is this is just an info message by a service, stating that the JVM arguments provided to it instructs it to create a dump of the heap if the service ran out of memory and that the appearance of this message itself does not indicate that the node has run out of memory.

Does that INFO entry mean I am running out memory?

UPDATE I tried to do some research and I found this https://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-VM/html/clopts.html

This specific option means that JVM will generate heap dump if it encounters out of memory situation - this is very useful for understanding why OOM happened - for example, you may have too many tombstones in the memory, etc.

But all JVM options are applied to Cassandra as just another JVM-based product, so Oracle's documentation is applicable.

QUESTION

Thread Dump: What to look for to determine the thread responsible for 100% CPU?

Asked 2020-Apr-30 at 07:25

Attempting to troubleshoot a 100% CPU consumption on a large system running hundreds of threads concurrently, I generated a thread dump with the help of this Oracle's Diagnosing a Looping Process article.

To find which thread is responsible for this high CPU consumption, I know that I should focus on on the threads that are in the RUNNABLE state, but there are dozens of them. So it is like finding a needle in a haystack.

What else should I be looking for among all those threads in the RUNNABLE state, to focus on the particular thread that is responsible for the 100% CPU consumption?

On linux:
1. You can get the busiest thread id by command: top -Hp $(pidof java)
2. And then convert the thread id to hexadecimal: prinrf "%x\n" {the tid}
3. Now, search the hexadecimal id in the thread-dump, That is the thread that consumes the most CPU.

On other operation systems, google How to find the busiest thread in a process.
