To hide or store in a cache. See Synonyms at hide1.
[French, from Middle French, from cacher, to hide, from Old French, from Vulgar Latin *coācticāre, to store, pack together, frequentative of Latin coāctāre, to constrain, frequentative of cōgere, coāct-, to force; see cogent.]
In evasion and recovery operations, source of subsistence and supplies, typically containing items such as food, water, medical items, and/or communications equipment, packaged to prevent damage from exposure and hidden in isolated locations by such methods as burial, concealment, and/or submersion, to support evaders in current or future operations. See also concealment; evader; evasion; evasion and recovery; recovery; recovery operations.

cache - (computer science) RAM memory that is set aside as a specialized buffer storage that is continually updated; used to optimize data transfers between system elements with different characteristics
buffer storage, buffer store, buffer - (computer science) a part of RAM used for temporary storage of data that is waiting to be sent to a device; used to compensate for differences in the rate of flow of data between components of a computer system
disk cache - a cache that stores copies of frequently used disk sectors in random access memory (RAM) so they can be read without accessing the slower disk

WHAT'S NEW: Nvidia claims that the new GPU delivers a "major jump in overall performance and power efficiency for today's most popular games." "GeForce GTX 16-series gaming laptops take advantage of all of the shader innovations in the 12th generation NVIDIA Turing GPU architecture, including concurrent floating point and integer operations, unified cache architecture with 3x the L1 cache compared to the Pascal generation, and turbocharged performance using adaptive shading technology," the company said in a statement.
It counts memory transfers between different memory levels and provides arithmetic intensities for L1 cache (this one is called the cache aware roofline model, CARM), L2, L3, and DRAM.
While SGX enclaves were designed to be impervious to Spectre and Meltdown, it appears that through the Foreshadow flaw, an attacker could gain access to data residing in L1 cache.
The paper tackles important technical aspects that can affect the overall performance of a CUDA application such as: the optimal alignment in memory of the data that is to be processed, obtaining optimal memory access patterns that facilitate the retrieving of instructions; aligning to the L1 cache line according to its size, taking into account the balance achieved between single or double precision and the effect on how much memory is being used; joining more kernel functions into a single one in certain situations, benefiting from the increased speedup offered by putting into use the shared and cache memory, adjusting the code to the available memory bandwidth by taking into account the memory latency and the need to transfer data between the host and the device.
