A data connector to interface with a sled of a data center includes a main body, a plurality of guide shafts, and a cover. The main body includes electrical contacts. The guide shafts are associated with the main body, and each guide shaft extends along a corresponding longitudinal axis. The cover is coupled to the guide shafts such that the cover is slidable along the guide shafts in a direction defined by the longitudinal axes. The cover includes a movable door to provide protection to the electrical contacts of the main body when not in use.

A compute device to generate deterministic compressed streams receives a current string to be matched to one or more prior instances of the current string, the current string being located within an input buffer and the one or more prior instances located within a history buffer. The compute device identifies a limited subset of index memory designated for storing pointers to the prior instances, identifying a reserved slop region in the index memory, and compares the current string to a prior instance, locating the at least one prior instance using at least one pointer to the at least one prior instance. The at least one pointer is stored within the limited subset of the index memory, and the compute device also prohibits use of any pointers stored in the reserved slop region of the index memory. Other embodiments are described and claimed.

Technologies for flexibly compressing data include a computing device having an accelerator complex that is to receive a compression job request and schedule the compression job request for one or more hardware compression resources of the accelerator complex. The accelerator complex is further to perform the compression job request with the one or more hardware compression resources in response to scheduling the compression job request and to communicate uncompressed data and compressed data with an I/O subsystem of the computing device in response to performing the compression job request. Other embodiments are described and claimed.

Technologies for high-ratio compression with heterogeneous history buffers include a computing device having an accelerator complex with a large history buffer and a small history buffer. The large history buffer has a larger size than the small history buffer. For example, the small history buffer may be 32 kilobytes and the large history buffer may be 64 kilobytes, 1 megabyte, or larger. The large history buffer is coupled to a large-buffer compare core that searches for matches in the large history buffer, finds a best match, and forwards the best match to a small-buffer compare core. The small-buffer compare core searches the small history buffer for matches, receives the match forwarded from the large-buffer compare core, and determines a best match from the matches in the small history buffer and the forwarded match. Other embodiments are described and claimed.

Technologies for an accelerator interface over Ethernet are disclosed. In the illustrative embodiment, a network interface controller of a compute device may receive a data packet. If the network interface controller determines that the data packet should be pre-processed (e.g., decrypted) with a remote accelerator device, the network interface controller may encapsulate the data packet in an encapsulating network packet and send the encapsulating network packet to a remote accelerator device on a remote compute device. The remote accelerator device may pre-process the data packet (e.g., decrypt the data packet) and send it back to the network interface controller. The network interface controller may then send the pre-processed packet to a processor of the compute device.

Technologies for managing network statistic counters include a network interface controller (NIC) of a computing device configured to identify a statistic counter of and a software consumer associated with a received network packet and identify an active counter page as a function of the identified software consumer. The NIC is further configured to read a value of the statistic counter stored at a counter memory address of a corresponding counter identifier entry of the identified active counter page, increment a read value of the statistic counter, and write the incremented value of the statistic counter back to the counter memory address. Additionally, in response to detecting a notification triggering event, generating a notification message that includes a present value of the statistic counter and a present value of each of the other statistic counters of the active counter page, and transmit the generated notification message to the software consumer. Other embodiments are described herein.

Technologies for processing network packets in an agent-mesh architecture include a network interface controller (NIC) of a computing device configured to write, by a network fabric interface of a memory fabric of the NIC, a received network packet to the memory fabric in a distributed fashion. The network fabric interface is configured to send an event message indicating the received network packet to a packet processor communicatively coupled to the memory fabric. The packet processor is configured to read, in response to having received the generated event message, at least a portion of the received network packet from the memory fabric, identify an agent of the NIC for additional processing of the received network packet, generate a network packet received event message indicating the received network packet is available for processing, and transmit the network packet received event message to the identified agent. Other embodiments are described herein.

Technologies for processing network packets by a network interface controller (NIC) of a computing device include a network interface, a packet processor, and a controller device of the NIC, each communicatively coupled to a memory fabric of the NIC. The packet processor is configured to receive an event message from the memory fabric and transmit a message to the controller device, wherein the message indicates the network packet has been received and includes the memory fabric location pointer. The controller device is configured to fetch at least a portion of the received network packet from the memory fabric, write an inbound descriptor usable by one or more on-die cores of the NIC to perform an operation on the fetched portion, and restructure the network packet as a function of an outbound descriptor written by the on-die cores subsequent to performing the operation. Other embodiments are described herein.

A data compression apparatus of the invention includes a data acquisition unit to acquire n integers from encoding data, an integer division unit to divide each integer of the n integers into a second integer represented by low-order bits whose number of divided bits is b and a first integer represented by high-order bits obtained by excluding the low-order bits from each integer of the n integers and to output n first integers and n second integers, a first encoding unit to encode and output the n first integers as a first code represented by binary data having a number of bits that is a natural-number times the number of unit bits of L, and a second encoding unit to encode and output the n second integers as a second code.

An encoding apparatus reads text data of an encoding target, encodes each character or word in the text data of the encoding target by using a bit map type index in which an appearance position is associated with each of the encoded characters or words, appearing on the text data of the encoding target, as bit map data, and updates the bit map type index with respect to the encoded character or word.
