caching

问题 I just noticed it's at all possible to have (CUDA kernel) memory accesses uncached (see e.g. this answer here on SO). Can this be done... For a single kernel individually? At run time rather than at compile time? For writes only rather than for reads and writes? 回答1: Only if you compile that kernel individually, because this is an instruction level feature which is enabled by code generation. You could also use inline PTX assembler to issue ld.global.cg instructions for a particular load

问题 Pardon if this is more serverfault vs. stackoverflow. It seems to be on the border. We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem: The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server. What we've tried so

问题 I am new in django/redis and i'm starting to familiarize with heroku redis addon. However, i can only use set and get . When i'm trying to use other methods like hset , i get this error : 'RedisCache' object has no attribute cache.hset('key', 'value') How can i manage this ? 来源： https://stackoverflow.com/questions/48551562/how-to-use-hset-with-django-redis-cache

问题 Recently, I discussed why there is a volatile mark at seq in Java Actors demo @volatile private var seq = 0L private def nextSeq: Long = { val next = seq seq += 1 next } One answer was that threads can be migrated and variables lost (other cores will have incoherent values in their private caches). But, you not normally mark every variable with volatile to enable multicore execution. So, cores must flush the caches whenever context is switched. But, I cannot find this statement pronounced

问题 Normally for .js and .css file we will append a version during build like xx.js?v=123 , and then after website deploy, we can get the new version of js and CSS. But I don't see a place talking about how to make the index.html file upgrade when website deployment happen. And we do see in IE that the HTML content should have been changed but it still use the old HTML content. One solution I find from google is to <meta http-equiv="Cache-control" content="no-cache"> However, I am not sure

问题 I have a Kotlin JVM server application using coroutines and I need to put a cache in front of a non-blocking network call. I figure I can use a Caffeine AsyncLoadingCache to get the non-blocking cache behaviour I need. The AsyncCacheLoader interface I would need to implement uses CompletableFuture . Meanwhile, the method I want to call to load the cache entries is a suspend function. I can bridge the gap like this: abstract class SuspendingCacheLoader<K, V>: AsyncCacheLoader<K, V> { abstract
