Launch 7001

[Sourabh Doherty]

However, this code runs successfully on another laptop with the same driver version (511.79) but different GPU (my laptop has a M1000M). Both laptops are using CUDA 11.4 and OptiX 7.4. Does anyone know if my GPU is causing the issue or something else?

Please always provide the following system configuration information when asking about OptiX issues:
OS version, installed GPU(s), VRAM amount, display driver version, OptiX (major.minor.micro) version, CUDA toolkit version (major.minor) used to generate the input PTX, host compiler version.

Your laptop with the Maxwell GPU is failing? What is the other one not failing?
Did this work before? Means is that a regression with the 511.79 display drivers?
Which streaming multiprocessor target did you use for the *.cu to *.ptx source code compilation?
(Maxwell needs SM 5.x versions and SM 5.0 is deprecated in CUDA 11. Should still work though, you would just need to suppress the deprecation warnings with -Wno-deprecated-gpu-targets on the nvcc command line.)

If that launch failure code 7001 is from OptiX, that is an OPTIX_ERROR_INVALID_VALUE.
Please try setting a logger callback with the highest level 4 inside the OptixDeviceContextOptions and enable the validation mode in there as well in debug targets. (You can find examples doing that inside the OptiX SDK.)

When you order from launchx431.net, you will receive a confirmation email. Once your order is shipped, you will be emailed the tracking information for your order's shipment. You can choose your preferred shipping method on the Order Information page during the checkout process.

In addition, the transit time depends on where you're located and where your package comes from. If you want to know more information, please contact the customer service. We will settle your problem as soon as possible. Enjoy shopping!

I have installed oracle forms and reports 12c on linux server. firewall and ports are open for the form server(9001) , report server (9002) but still not able to open the below from the client machine( windows).
All the services are up and running on the server. Is there any configuration to access from client machine ? :9001/forms/frmservlet or :9002/reports/rwservlet/showenv

Epyc (stylized as EPYC) is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture. Introduced in June 2017, they are specifically targeted for the server and embedded system markets.[1]

Epyc processors share the same microarchitecture as their regular desktop-grade counterparts, but have enterprise-grade features such as higher core counts, more PCI Express lanes, support for larger amounts of RAM, and larger cache memory. They also support multi-chip and dual-socket system configurations by using the Infinity Fabric interconnect.

In March 2017, AMD announced plans to re-enter the server market with a platform based on the Zen microarchitecture, codenamed Naples, and officially revealed it under the brand name Epyc in May.[2] That June AMD officially launched Epyc 7001 series processors, offering up to 32 cores per socket, and enabling performance that allowed Epyc to be competitive with the competing Intel Xeon Scalable product line.[3] In August 2019, the Epyc 7002 "Rome" series processors, based on the Zen 2 microarchitecture, launched, doubling the core count per socket to 64, and increasing per-core performance dramatically over the last generation architecture.

In March 2021, AMD launched the Epyc 7003 "Milan" series, based on the Zen 3 microarchitecture.[4] Epyc Milan brought the same 64 cores as Epyc Rome, but with much higher per-core performance, with the Epyc 7763 beating the Epyc 7702 by up to 22 percent despite having the same number of cores and threads.[5] A refresh of the Epyc 7003 "Milan" series with 3D V-Cache, named Milan-X, launched on March 21, 2022, using the same cores as Milan, but with an additional 512 MB of cache stacked onto the compute dies, bringing the total amount of cache per CPU to 768 MB.[6]

In November 2021, AMD detailed the upcoming generations of Epyc, and unveiled the new LGA-6096 SP5 socket that would support the new generations of Epyc chips. Codenamed Genoa, these CPUs are based on the Zen 4 microarchitecture and built on TSMC's N5 node, supporting up to 96 cores and 192 threads per socket, alongside 12 channels of DDR5,[7] and 128 PCIe 5.0 lanes. Genoa also became the first x86 server CPU to support Compute Express Link 1.1,[8] or CXL, allowing for further expansion of memory and other devices with a high bandwidth interface built on PCIe 5.0. AMD also shared information regarding the sister chip of Genoa, codenamed Bergamo. Bergamo is based on a modified version of Zen 4 named Zen 4c, designed to allow for much higher core counts and efficiency at the cost of lower single-core performance, targeting cloud providers and workloads, compared to traditional high performance computing workloads.[9] It is compatible with Socket SP5, and supports up to 128 cores and 256 threads per socket.[10]

In November 2022, AMD launched their 4th generation Epyc "Genoa" series of CPUs. Some tech reviewers and customers had already received hardware for testing and benchmarking, and third party benchmarks of Genoa parts were immediately available. The flagship part, the 96 core Epyc 9654, set records for multi-core performance, and showed up to 4 performance compared to Intel's flagship part, the Xeon Platinum 8380. High memory bandwidth and extensive PCIe connectivity removed many bottlenecks, allowing all 96 cores to be utilized in workloads where previous generation Milan chips would have been I/O-bound.

In June 2023, AMD began shipping the 3D V-Cache enabled Genoa-X lineup, a variant of Genoa that uses the same 3D die stacking technology as Milan-X to enable up to 1152 MB of L3 cache, a 50% increase over Milan-X, which had a maximum of 768 MB of L3 cache.[11] On the same day, AMD also announced the release of their cloud optimized Zen 4c SKUs, codenamed Bergamo, offering up to 128 cores per socket, utilizing a modified version of the Zen 4 core that was optimized for power efficiency and to reduce die space. Zen 4c cores do not have any instructions removed compared to standard Zen 4 cores; instead, the amount of L3 cache per CCX is reduced from 32 MB to 16 MB, and the frequency of the cores is reduced.[12] Bergamo is socket compatible with Genoa, using the same SP5 socket and supporting the same CXL, PCIe, and DDR5 capacity as Genoa.[13]

In September 2023, AMD launched their low power and embedded 8004 series of CPUs, codenamed Siena. Siena utilizes a new socket, called SP6, which has a smaller footprint and pin count than the SP5 socket of its contemporary Genoa processors. Siena utilizes the same Zen 4c core architecture as Bergamo cloud native processors, allowing up to 64 cores per processor, and the same 6 nm I/O die as Bergamo and Genoa, although certain features have been cut down, such as reducing the memory support from 12 channels of DDR5 to only 6, and removing dual socket support.[14]

Epyc CPUs use a multi-chip module design to enable higher yields for a CPU than traditional monolithic dies. First generation Epyc CPUs are composed of four 14 nm compute dies, each with up to 8 cores.[20][21] Cores are symmetrically disabled on dies to create lower binned products with fewer cores but the same I/O and memory footprint. Second and Third gen Epyc CPUs are composed of eight compute dies built on a 7 nm process node, and a large input/output (I/O) die built on a 14 nm process node.[22] Third gen Milan-X CPUs use advanced through-silicon-vias to stack an additional die on top of each of the 8 compute dies, adding 64 MB of L3 cache per die.[23]

Epyc CPUs supports both single socket and dual socket operation. In a dual socket configuration, 64 PCIe lanes from each CPU are allocated to AMD's proprietary Infinity Fabric interconnect to allow for full bandwidth between both CPUs.[24] Thus, a dual socket configuration has the same number of usable PCIe lanes as a single socket configuration. First generation Epyc CPUs had 128 PCIe 3.0 lanes, while second and third generation had 128 PCIe 4.0 lanes. All current Epyc CPUs are equipped with up to eight channels of DDR4 at varying speeds, though next gen Genoa CPUs are confirmed by AMD to support up to twelve channels of DDR5.[7][25]

Unlike Opteron, Intel equivalents and AMD's desktop processors (excluding Socket AM1), Epyc processors are chipset-free - also known as system on a chip. That means most features required to make servers fully functional (such as memory, PCI Express, SATA controllers, etc.) are fully integrated into the processor, eliminating the need for a chipset to be placed on the mainboard. Some features may require the use of additional controller chips to utilize.

Initial reception to Epyc was generally positive.[25] Epyc was generally found to outperform Intel CPUs in cases where the cores could work independently, such as in high-performance computing and big-data applications. First generation Epyc fell behind in database tasks compared to Intel's Xeon parts due to higher cache latency.[25] In 2021 Meta Platforms selected Epyc chips for its metaverse data centers.[26]

Epyc Genoa was well received, as it offered improved performance and efficiency compared to previous offerings, though received some criticism for not having 2 DIMMs per channel configurations validating, with some reviewers calling it an "incomplete platform".[27]

In November 2018, AMD announced Epyc 2 at their Next Horizon event, the second generation of Epyc processors codenamed "Rome" and based on the Zen 2 microarchitecture.[37] The processors feature up to eight 7 nm-based "chiplet" processors with a 14 nm-based IO chip providing 128 PCIe 4.0 lanes in the center interconnected via Infinity Fabric. The processors support up to 8 channels of DDR4 RAM up to 4 TB, and introduce support for PCIe 4.0. These processors have up to 64 cores with 128 SMT threads per socket.[38] The 7 nm "Rome" is manufactured by TSMC.[22] It was released on August 7, 2019.[39] It has 39.5 billion transistors.[40]
