amazon web services - AWS ECS running a task that requires many cores -

-

i conceptually trying understand how use aws ecs run "cluster" jobs.

i have scientific software inside docker container, natively takes advantage of many cores underlying instance has offer.

my question in case is, can use aws ecs "increase" number of "visible" cores task running inside docker container. instance, "cluster" limited single instance? or "cluster" expandable multiple instances?

i haven't been able find answers looking through aws docs.

i had similar situation moving python app used script spawn copies of based on number of cores. answer isn't ecs problem docker best practice... should strive use 1 process per container. (see https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/)

how ended implementing using dockerfile run each process , used essential ecs tasks reload if task died.

your cluster collection of ec2 instances ecs service running. each instance has number of cpu 'units' (typically 1024 units === 1 core) , ram. profiled app @ peak load , tweaked mix until got liked it. if app can use more cpu that, try giving 2048 cpu or other amount , see how performs. used meros (https://meros.io/) profile app.

hope helps!

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
